Overview
SITRANS P250 transmitter for differential pressure
The SITRANS P250 transmitter measures the differential pres-
sure of liquids and gases.
Benefits
High measuring accuracy
Sturdy stainless steel enclosure
For aggressive and non-aggressive media
For the measurement of the differential pressure of liquids and
gases
Temperature-compensated measuring cell
Compact design
Application
The SITRANS P250 transmitter for differential pressure is prima-
rily used in the following industries:
Chemical industry
Pharmaceutical industry
Food industry
Mechanical engineering
• Shipbuilding
Water supply
Design
Main components:
Stainless steel enclosure with piezo-resistive ceramic measur-
ing cell and (temperature-compensated) electronics module.
Process connection made of stainless steel in diverse designs
(see Selection and ordering data)
Electrical connection through connectors acc. to EN 175301-
803-A and round connectors M12, as well as with permanently
fixed cable
Function
The pressure transmitter measures the differential pressure of
liquids and gases.
Mode of operation
SITRANS P250 pressure transmitter, function diagram
The piezo-resistive ceramic measuring cell (membrane) has a
Wheatstone bridge circuit, on which the operating pressure P1
and P2 of the media acts at both ends.
The voltage output from the measuring cell is converted by an
amplifier into an output current of 4 to 20 mA or an output voltage
of 0 to 5 or 10 V DC.
The output current and voltage are linearly proportional to the in-
put pressure.

Overview
SITRANS P pressure transmitters, ZD series, are for measuring
the gage pressure, absolute pressure and level of liquids and
gases.
They are used to indicate and monitor the pressure measured at
the point of installation. ZD pressure transmitters are available in
an axial and a radial version.
Benefits
Robust stainless steel housing with 2 connection versions
Integrated display with status messages
Thin-film measuring cell with ceramic diaphragm
2-wire system, 4 ... 20 mA
Parameterizable using keys underneath the housing cover
Range adjustment 1:5 (max. 1:10)
Measuring accuracy < 0.25% (typical)
Application
The ZD is a configurable pressure transmitter for measuring the
gage and absolute pressure of gases, liquids and vapor.
It is equipped with a display for indicating the pressure value at
the point of installation.
SITRANS P pressure transmitters, ZD series, are used in the fol-
lowing industrial areas for example:
Chemical industry
Mechanical engineering
Food industry
Pharmaceutical industry

Design
The pressure transmitter is comprised of a thin-film measuring
cell with a ceramic diaphragm, an electronics board and a digi-
tal indicator.
All parts are accommodated in a stainless steel field housing
(80 mm) with a glass cover and stainless steel process con-
nection.
At the rear of the housing is the electrical connection for the volt-
age supply using a current loop 4 ... 20 mA. The connection is
made with a plug connector.
At the front of the housing is the 5-digit display behind a glass
cover. Underneath the display are the 3 keys for parameterizing
the pressure transmitter. Above the display are a green and a red
LED for indicating the operating status.
The ZD pressure transmitter is available in two versions (see "Di-
mension drawing"):
In the radial version (type A) the display is fitted in parallel with
the process connection. The display can be rotated by up to
±120° relative to the process connection.
In the axial version (type B) the display is at right angles to the
process connection. The display can be rotated by 360° relative
to the process connection.

SITRANS P measuring instruments for pressure
Transmitters for food, pharmaceuticals and biotechnology
SITRANS P Compact
for gage and absolute pressure
2/21
Siemens FI 01 · 2009
2
Overview
The SITRANS P Compact pressure transmitter is designed for
the special requirements of the food, pharmaceutical and bio-
technology industries.
The use of high-grade materials guarantees compliance with hy-
giene regulations.
Particular value has been placed on a high surface quality. It is
therefore possible, for example, to guarantee roughness values
down to Ra=0.4μm (1.57 10-5 inch) in the wetted area
(welded seam area Ra<0.8μm (3.15 10-5 inch)). The system
can be electropolished in addition.
A further important feature is the hygiene-based design of the
process connection by means of various aseptic connections.
The completely welded stainless steel housing can be designed
up to degree of protection IP67.
Using appropriate thermal decouplers, the SITRANS P Compact
pressure transmitter can be used for process temperatures up to
200 °C (392 °F).
Benefits
Measuring ranges from 0 to 160 mbar (0 to 2.32 psi) to 0 to
40 bar (0 to 580 psi)
Linearity error including hysteresis < +0.2% of full-scale value
Piezo-resistive measurement system, vacuum-proof and over-
load-proof
Hygiene-based design according to EHEDG, FDA and GMP
recommendations
Material and surface quality according to hygiene require-
ments
Wetted parts made of stainless steel; completely welded
Signal output 4 to 20 mA (0 to 20 mA as option)
Stainless steel housing with degree of protection IP65 (IP67 as
option)
Process temperature up to 200 °C (392 °F)
Explosion protection II 2G EEx [ib] IIC T6 to ATEX
Easy and safe to clean
Application
The SITRANS P Compact pressure transmitter is designed for
the special requirements of the food, pharmaceutical and bio-
technology industries.
The use of high-grade materials guarantees compliance with hy-
giene regulations.
The SITRANS P Compact pressure transmitter is available in
many versions. Exact adaptation of the pressure transmitter to
conditions at the place of use is thus possible
Design
The electronics is potted to protect it against moisture, corrosive
atmospheres and vibration.
Notes on operating the pressure transmitter
Compensation of internal atmospheric pressure
Compensation of the internal atmospheric pressure of the
SITRANS P Compact pressure transmitters is performed as fol-
lows:
in the plug versions by means of the screwed gland (IP65)
in the field housings by means of an integral sintered filter
(IP65) or a vented cable (IP67)
in versions with cable outlet by means of a vented cable (IP67)
In the absolute pressure range there is no need for compensa-
tion with respect to atmospheric pressure.
Note: These degrees of protection are only achieved under the
following conditions:
if the pressure transmitter is installed correctly
if the screwed glands are securely tightened
if the cable diameters agree with the nominal diameters of the
gaskets in the housing
Note: The integral EMC measures are only effective if the earth
connection is made correctly.
CE marking
The CE marking of the pressure transmitter certifies compliance
with the guidelines of the European Council (9/336/EC), the EMC
law (13.11.1992), as well as the applicable generic standards.
Interference-free operation in systems and plants is achieved
only if the specifications for shielding, earthing, cable routing
and electrical isolation are observed during installation and as-
sembly.
Hazardous areas
Note: Electrical equipment in hazardous areas must only be in-
stalled and operated by trained personnel.
Modifications to units and connections result in cancellation of
the explosion protection and guarantee.
With intrinsically-safe circuits, make sure that equipotential
bonding exists throughout the complete cabling inside and out-
side of the hazardous area. The limits specified in the ATEX ap-
proval must be observed.

Function
The process pressure acts on a piezo-resistive semiconductor
measuring bridge through a remote seal and a transmission liq-
uid. The pressure transmitter converts the pressure values into a
load-independent current.
A compensation network makes the output signal largely inde-
pendent of the ambient temperature. As a result of a specially
adapted remote seal connection with minimized volume, the in-
fluence of the process temperature on the output signal is
greatly reduced compared to a conventional screw connection.
The pressure transmitters can be powered with a non-regulated
DC voltage of 10 to 30 V. Output signals common to measuring
technology are available.

SITRANS P300 for gage and absolute pressure
2/28 Siemens FI 01 · 2009
2
Overview
The SITRANS P300 is a digital pressure transmitter for gage and
absolute pressure. All conventional thread versions are available
as process connections. In addition, various hygiene-based
connections and flange connections with front-flush diaphragms
meet the requirements of a dead space free process connec-
tion.
The output signal is a load-independent direct current from 4 to
20 mA or a PROFIBUS PA signal, which is linearly proportional to
the input pressure. Communication is over HART protocol or
over PROFIBUS PA interface. Convenient buttons for easy local
operation of the basic settings of the pressure transmitter.
The SITRANS P300 has a single-chamber stainless steel casing.
The pressure transmitter is approved with "intrinsically safe" type
of protection It can be used in zone 1 or zone 0.
Benefits
High quality and long life
High reliability even under extreme chemical and mechanical
loads
Extensive diagnosis and simulation functions
Minimum conformity error
Small long-term drift
Wetted parts made of high-grade materials (such as stainless
steel, Hastelloy)
Measuring range 8 mbar to 400 bar
High measuring accuracy
Parameterization over control keys and HART communication
or PROFIBUS PA communication
Application
The pressure transmitter is available in versions for gage pres-
sure and for absolute pressure. The output signal is always a
load-independent direct current from 4 to 20 mA or a
PROFIBUS PA signal, which is linearly proportional to the input
pressure. The pressure transmitter measures aggressive, non-
aggressive and hazardous gases, as well as vapors and liquids.
It can be used for the following measurement types:
Gage pressure
Absolute pressure
With appropriate parameter settings, it can also be used for the
following additional measurement types:
• Level
• Volume
• Mass
The "intrinsically-safe" EEx version of the transmitter can be in-
stalled in hazardous areas (zone 1). The transmitters are pro-
vided with an EC type examination certificate and comply with
the respective harmonized European standards of ATEX.
Gage pressure
This variant measures aggressive, non-aggressive and hazard-
ous gases, vapors and liquids.
The smallest measuring span is 10 mbar g, the largest 400 bar g.
Level
With appropriate parameter settings, the gage pressure variant
measures the level of aggressive, non-aggressive and hazard-
ous liquids.
For measuring the level in an open container you require one de-
vice; for measuring the level in a closed container, you require
two devices and a process control system.
Absolute pressure
This variant measures the absolute pressure of aggressive, non-
aggressive and hazardous gases, vapors and liquids.
The smallest measuring span is 8 mbar a, the largest 30 bar a.

Design
The device comprises:
• Electronics
• Housing
Measuring cell
Perspective view of the SITRANS P300
The housing has a screw-on cover (3), with or without an inspec-
tion window depending on the version. The electrical terminal
housing, the buttons for operation of the device and, depending
on the version, the digital display are located under this cover.
The connections for the auxiliary power UH and the shield are in
the terminal housing. The cable gland is mounted on the side of
the housing. The measuring cell with the process connection (5)
is located on the underside of the housing. Depending on the
version of the device, the measuring cell with the process con-
nection may differ from the one shown in the diagram.
Function
Operation of the electronics with HART communication
Function diagram of electronics
The input pressure is converted into an electrical signal by the
sensor (1). This signal is amplified by the measuring amplifier (2)
and digitalized in an analog to digital converter (3). The digital
signal is analyzed in a microcontroller (4) and corrected with re-
gard to linearity and thermal characteristics. In a digital to ana-
log converter (5) it is then converted into the output current of 4
to 20 mA. A diode circuit provides reverse voltage protection.
You can make an uninterrupted current measurement with a low-
ohm ammeter at the connection (10). The data specific to the
measuring cell, the electronic data and parameter settings are
stored in two non-volatile memories (6). The first memory is
linked with the measuring cell, the second with the electronics.
The buttons (8) can be used to call up individual functions, so-
called modes. If you have a device with a digital display (9), you
can use this to track mode settings and other messages. The ba-
sic mode settings can be changed with a computer via the HART
modem (7).

Operation of the electronics with PROFIBUS PA communica-
tion
Function diagram of electronics
The input pressure is converted into an electrical signal by the
sensor (1). This signal is amplified by the measuring amplifier (2)
and digitalized in an analog to digital converter (3). The digital
signal is analyzed in a microcontroller (4) and corrected with re-
gard to linearity and thermal characteristics. It is then made
available at the PROFIBUS PA over an electrically isolated
PROFIBUS PA interface (7). The data specific to the measuring
cell, the electronic data and parameter settings are stored in two
non-volatile memories (6). The first memory is linked with the
measuring cell, the second with the electronics.
The buttons (8) can be used to call up individual functions, so-
called modes. If you have a device with a digital display (9), you
can use this to track mode settings and other messages. The ba-
sic mode settings can be changed with a computer over the bus
master (12).
Mode of operation of the FOUNDATION Fieldbus
electronics
Function diagram of electronics
The bridge output voltage created by the sensor (1, Figure
"Function diagram of electronics") is amplified by the instrument
amplifier (2) and digitized in the analog-to-digital converter (3).
The digital information is evaluated in the microcontroller, its lin-
earity and temperature response corrected, and provided on the
FOUNDATION Fieldbus through an electrically isolated
FOUNDATION Fieldbus Interface (7).
The data specific to the measuring cell, the electronics data, and
the parameter data are stored in the two non-volatile memories
(6). The one memory is coupled to the measuring cell, the other
to the electronics. As the result of this modular design, the elec-
tronics and the measuring cell can be replaced separately from
each other.
Using the three input keys (8) you can parameterize the pressure
transmitter directly at the point of measurement. The input keys
can also be used to control the view of the results, the error mes-
sages and the operating modes on the digital display (9).
The results with status values and diagnostic values are trans-
ferred by cyclic data transmission on the FOUNDATION
Fieldbus. Parameterization data and error messages are trans-
ferred by acyclic data transmission. Special software such as
National Instruments Configurator is required for this.

Measuring cell for gage pressure
Measuring cell for gage pressure, function chart
The input pressure (pe) is transferred to the gage pressure sen-
sor (6) via the seal diaphragm (4) and the filling liquid (5), dis-
placing its measuring diaphragm. The displacement changes
the resistance value of the four piezo resistors in the measuring
diaphragm in a bridge circuit. The change in the resistance
causes a bridge output voltage proportional to the input pres-
sure.
The transmitters with spans 63 bar measure the input pressure
against atmosphere, those with spans 160 bar against
vacuum.
Measuring cell for absolute pressure
Measuring cell for absolute pressure, function chart
The input pressure (pe) is transferred to the absolute pressure
sensor (5) via the seal diaphragm (3) and the filling liquid (4),
displacing its measuring diaphragm. The displacement
changes the resistance value of the four piezo resistors in the
measuring diaphragm in a bridge circuit. The change in the re-
sistance causes a bridge output voltage proportional to the input
pressure.

Parameterization of SITRANS P300
Depending on the version, there are a range of options for pa-
rameterizing the pressure transmitter and for setting or scanning
the parameters.
Parameterization using the input keys (local operation)
With the input keys you can easily set the most important param-
eters without any additional equipment.
Parameterization using HART communication
Parameterization using HART communication is performed with
a HART communicator or a PC.
Communication between a HART communicator and a pressure transmit-
ter
When parameterizing with the HART communicator, the connec-
tion is made directly to the 2-wire system.
HART communication between a PC communicator and a pressure
transmitter
When parameterizing with a PC, the connection is made through
a HART modem.
The signals needed for communication in conformity with the
HART 5.x or 6.x protocols are superimposed on the output cur-
rent using the Frequency Shift Keying (FSK) method.

Parameterization through PROFIBUS PA interface
Fully digital communication through PROFIBUS PA, profile 3.0, is
particularly user-friendly. The PROFIBUS puts the DS III PA is in
connection with a process control system, e.g. SIMATIC PSC 7.
Communication is possible even in a potentially explosive envi-
ronment.
For parameterization through PROFIBUS you need suitable soft-
ware, e.g. SIMATIC PDM (Process Device Manager).
Parameterization through FOUNDATION Fieldbus Interface
Fully digital communication through FOUNDATION Fieldbus is
particularly user-friendly. Through the FOUNDATION Fieldbus
the P300 FF is connected to a process control system. Commu-
nication is possible even in a potentially explosive environment.
For parameterization through the FOUNDATION Fieldbus you
need suitable software, e.g. National Instruments Configurator.

Overview
The SITRANS P300 and DS III pressure transmitters have been
fitted with special process connections for the paper industry.
With the two process connection threads 1½" and 1" flush at the
front, the SITRANS P300 and DS III transmitters can be used for
all processes in the paper industry.
SITRANS P300 and DS III series pressure transmitters are digital
pressure transmitters featuring extensive user-friendliness and
high accuracy. The parameterization is performed using control
keys, over HART communication, PROFIBUS PA or
FOUNDATION Fieldbus interface (DS III only).
Extensive functionality enables the pressure transmitter to be
precisely adapted to the plant’s requirements. Operation is very
simple in spite of the numerous setting options.
Transmitters with type of protection "Intrinsic safety" and "Explo-
sion-proof" may be installed within potentially explosive atmo-
spheres (zone 1) or in zone 0. The transmitters are provided with
an EC type examination certificate and comply with the corre-
sponding harmonized European standards (ATEX).
Various versions of the pressure transmitters are available for
measuring:
Gage pressure

Application
The pressure transmitters of the DS III series, can be used in in-
dustrial areas with extreme chemical and mechanical loads.
Electromagnetic compatibility in the range 10 kHz ... 1 GHz
makes the DS III pressure transmitters suitable for locations with
high electromagnetic emissions.
Pressure transmitters with type of protection "Intrinsic safety" and
"Explosion-proof" may be installed within potentially explosive at-
mospheres (zone 1) or in zone 0. The pressure transmitters are
provided with an EC type examination certificate and comply
with the corresponding harmonized European standards
(ATEX).
Pressure transmitters with the type of protection "Intrinsic safety"
for use in zone 0 may be operated with power supply units of cat-
egory "ia" and "ib".
The transmitters can be equipped with various designs of re-
mote seals for special applications such as the measurement of
highly viscous substances.
The pressure transmitter can be operated locally over 3 control
keys or programmed externally over HART communication or
over PROFIBUS PA or FOUNDATION Fieldbus interface (only
DS III).

Design
SITRANS P, DS III series
Device front view, SITRANS P DS III
The transmitter comprises a range of different components, de-
pending on the order specifications. The various options are
listed in the ordering information. The components described
below are the same for all transmitters.
The rating plate (3, Figure "Front view") with the Order No. is lo-
cated on the side of the housing. The specified number together
with the ordering information provide details on the optional de-
sign details and on the possible measuring range (physical
properties of built-in sensor element).
The approval label is located on the opposite side.
The housing is made of die-cast aluminium or stainless steel pre-
cision casting. A round cover is screwed on at the front and rear
of the housing. The front cover (6) can be fitted with a viewing
pane so that the measured values can be read directly on the
digital display. The inlet (4) for the electrical connection is lo-
cated either on the left or right side. The unused opening on the
opposite side is sealed by a blanking plug. The protective earth
connection is located on the rear of the housing.
The electrical connections for the power supply and screen are
accessible by unscrewing the rear cover. The bottom part of the
housing contains the measuring cell with process connection
(1). The measuring cell is prevented from rotating by a locking
screw (8). As the result of this modular design, the measuring
cell and the electronics can be replaced separately from each
other. The set parameter data are retained.
At the top of the housing is a plastic cover (5), which hides the
input keys.

Perspective view of the SITRANS P300
The housing has a screwable cover (3), with or without an in-
spection window depending on the version. The electrical termi-
nal housing, the buttons for operation of the device and, de-
pending on the version, the digital display are located under this
cover. The connections for the auxiliary power UH and the shield
are in the terminal housing. The cable gland is on the side of the
housing. The measuring cell with the process connection (5) is
located on the underside of the housing. Depending on the ver-
sion of the device, the measuring cell with the process connec-
tion may differ from the one shown in the diagram.

Function
Operation of the electronics with PROFIBUS PA communica-
tion
Function diagram of electronics
The bridge output voltage created by the sensor (1, Figure
"Function diagram of electronics") is amplified by the instrument
amplifier (2) and digitized in the analog-to-digital converter (3).
The digital information is evaluated in a microcontroller, its linear-
ity and temperature response corrected, and converted in a dig-
ital-to-analog converter (5) into an output current of 4 to 20 mA.
The diode circuit (10) protects against incorrect polarity.
The data specific to the measuring cell, the electronics data, and
the parameter data are stored in the two non-volatile memories
(6). The one memory is coupled to the measuring cell, the other
to the electronics. As the result of this modular design, the elec-
tronics and the measuring cell can be replaced separately from
each other.
Using the 3 input keys (8) you can parameterize the pressure
transmitter directly at the point of measurement. The input keys
can also be used to control the view of the results, the error mes-
sages and the operating modes on the digital display (9).
The HART modem (7) permits parameterization using a protocol
according to the HART specification.
The pressure transmitters with spans 63 bar g measure the in-
put pressure compared to atmosphere, transmitters with spans
160 bar g compared to vacuum.
Operation of the electronics with PROFIBUS PA communica-
tion
Function diagram of electronics
The bridge output voltage created by the sensor (1, Figure
"Function diagram of electronics") is amplified by the instrument
amplifier (2) and digitized in the analog-to-digital converter (3).
The digital information is evaluated in the microcontroller, its lin-
earity and temperature response corrected, and provided on the
PROFIBUS PA through an electrically isolated PA interface (7).
The data specific to the measuring cell, the electronics data, and
the parameter data are stored in the two non-volatile memories
(6). The first memory is linked with the measuring cell, the sec-
ond with the electronics. This modular design means that the
electronics and the measuring cell can be replaced separately
from one another.
Using the three input keys (8) you can parameterize the pressure
transmitter directly at the point of measurement. The input keys
can also be used to control the view of the results, the error mes-
sages and the operating modes on the digital display (9).
The results with status values and diagnostic values are trans-
ferred by cyclic data transmission on the PROFIBUS PA. Param-
eterization data and error messages are transferred by acyclic
data transmission. Special software such as SIMATIC PDM is re-
quired for this.

Mode of operation of the FOUNDATION Fieldbus electronics
Function diagram of electronics
The bridge output voltage created by the sensor (1, Figure
"Function diagram of electronics") is amplified by the instrument
amplifier (2) and digitized in the analog-to-digital converter (3).
The digital information is evaluated in the microcontroller, its lin-
earity and temperature response corrected, and provided on the
FOUNDATION Fieldbus through an electrically isolated
FOUNDATION Fieldbus Interface (7).
The data specific to the measuring cell, the electronics data, and
the parameter data are stored in the two non-volatile memories
(6). The one memory is coupled to the measuring cell, the other
to the electronics. As the result of this modular design, the elec-
tronics and the measuring cell can be replaced separately from
each other.
Using the three input keys (8) you can parameterize the pressure
transmitter directly at the point of measurement. The input keys
can also be used to control the view of the results, the error mes-
sages and the operating modes on the digital display (9).
The results with status values and diagnostic values are trans-
ferred by cyclic data transmission on the FOUNDATION
Fieldbus. Parameterization data and error messages are trans-
ferred by acyclic data transmission. Special software such as
National Instruments Configurator is required for this.
Mode of operation of the measuring cell
Measuring cell for gage pressure with front-flush diaphragm
Measuring cell for gage pressure, with front-flush diaphragm, function
diagram
The pressure pe is applied through the process connection
(2, Figure "Measuring cell for gage pressure, with front-flush di-
aphragm for paper industry, function diagram") to the measuring
cell (1). This pressure is subsequently transmitted further
through the seal diaphragm (3) and the filling liquid (4) to the sil-
icon pressure sensor (5) whose measuring diaphragm is then
flexed. This changes the resistance of the four piezo-resistors fit-
ted in the diaphragm in a bridge circuit. This change in resis-
tance results in a bridge output voltage proportional to the input
pressure.
Parameterization
Depending on the version, there are a range of options for pa-
rameterizing the pressure transmitter and for setting or scanning
the parameters.
Parameterization using the input keys (local operation)
With the input keys you can easily set the most important param-
eters without any additional equipment.
Parameterization using HART communication
Parameterization using HART communication is performed with
a HART communicator or a PC.
Communication between a HART communicator and a pressure
transmitter
When parameterizing with the HART communicator, the connec-
tion is made directly to the 2-wire system.

HART communication between a PC communicator and a pressure
transmitter
When parameterizing with a PC, the connection is made through
a HART modem.
The signals needed for communication in conformity with the
HART 5.x or 6.x protocols are superimposed on the output cur-
rent using the Frequency Shift Keying (FSK) method.

Parameterization through PROFIBUS PA interface
Fully digital communication through PROFIBUS PA, profile 3.0, is
particularly user-friendly. The PROFIBUS puts the DS III PA is in
connection with a process control system, e.g. SIMATIC PSC 7.
Communication is possible even in a potentially explosive envi-
ronment.
For parameterization through PROFIBUS you need suitable soft-
ware, e.g. SIMATIC PDM (Process Device Manager).
Parameterization through FOUNDATION Fieldbus Interface
Fully digital communication through FOUNDATION Fieldbus is
particularly user-friendly. Through the FOUNDATION Fieldbus
the DS III FF is connected to a process control system. Commu-
nication is possible even in a potentially explosive environment.
For parameterization through the FOUNDATION Fieldbus you
need suitable software, e.g. National Instruments Configurator.

SITRANS P measuring instruments for pressure
Transmitters for gage, absolute and differential pressure, flow and level
DS III, DS III PA and DS III FF series
Technical description
2/63
Siemens FI 01 · 2009

Overview
SITRANS P pressure transmitters, DS III series, are digital pres-
sure transmitters featuring extensive user-friendliness and high
accuracy. The parameterization is performed using control keys,
over HART communication, PROFIBUS-PA or FOUNDATION
Fieldbus interface.
Extensive functionality enables the pressure transmitter to be
precisely adapted to the plant’s requirements. Operation is very
simple in spite of the numerous setting options.
Transmitters with type of protection "Intrinsic safety" and "Explo-
sion-proof" may be installed within potentially explosive atmo-
spheres (zone 1) or in zone 0. The transmitters are provided with
an EC type examination certificate and comply with the corre-
sponding harmonized European standards (ATEX).
The transmitters can be equipped with various designs of re-
mote seals for special applications such as the measurement of
highly viscous substances.
Various versions of the DS III pressure transmitters are available
for measuring:
Gage pressure
Absolute pressure
For differential pressure transmitters
Filling level
Mass level
Volume level
Volume flow
Mass flow
Benefits
High quality and long life
High reliability even under extreme chemical and mechanical
loads
For aggressive and non-aggressive gases, vapors and liquids
Extensive diagnosis and simulation functions
Separate replacement of measuring cell and electronics with-
out recalibration
Minimum conformity error
Small long-term drift
Wetted parts made of high-grade materials (e.g. stainless
steel, Hastelloy, gold, Monel, tantalum)
Infinitely adjustable span from 0.01 mbar to 400 mbar for
DS III with HART communication
Nominal measuring range from 1 to 400 bar for DS III PA
(PROFIBUS PA) and FF (FOUNDATION Fieldbus)
High measuring accuracy
Parameterization over control keys and HART communication,
PROFIBUS PA communication or FOUNDATION Fieldbus in-
terface.
Application
The pressure transmitters of the DS III series, can be used in in-
dustrial areas with extreme chemical and mechanical loads.
Electromagnetic compatibility in the range 10 kHz to 1 GHz
makes the DS III pressure transmitters suitable for locations with
high electromagnetic emissions.
Pressure transmitters with type of protection "Intrinsic safety" and
"Explosion-proof" may be installed within potentially explosive at-
mospheres (zone 1) or in zone 0. The pressure transmitters are
provided with an EC type examination certificate and comply
with the corresponding harmonized European standards
(ATEX).
Pressure transmitters with the type of protection "Intrinsic safety"
for use in zone 0 may be operated with power supply units of cat-
egory "ia" and "ib".
The transmitters can be equipped with various designs of re-
mote seals for special applications such as the measurement of
highly viscous substances.
The pressure transmitter can be operated locally over 3 control
keys or programmed externally over HART communication or
over PROFIBUS PA or FOUNDATION Fieldbus interface.

for DS III PA and FF: 250 mbar ... 5 bar (3.63 ... 72.5 psi)
Nominal diameter of the mounting flange
- DN 80 or DN 100
- 3 inch or 4 inch
In the case of level measurements in open containers, the low-
pressure connection of the measuring cell remains open (mea-
surement "compared to atmospheric").
In the case of measurements in closed containers, the lower-
pressure connection has to be connected to the container in or-
der to compensate the static pressure.
The wetted parts are made from a variety of materials, depend-
ing on the degree of corrosion resistance required.
Design
Front view
The transmitter consists of various components depending on
the order. The possible versions are listed in the ordering infor-
mation. The components described below are the same for all
transmitters.
The rating plate (3, Figure "Front view") with the Order No. is lo-
cated on the side of the housing. The specified number together
with the ordering information provide details on the optional de-
sign details and on the possible measuring range (physical
properties of built-in sensor element).
The approval label is located on the opposite side.
The housing is made of die-cast aluminium or stainless steel pre-
cision casting. A round cover is screwed on at the front and rear
of the housing. The front cover (6) can be fitted with a viewing
pane so that the measured values can be read directly on the
digital display. The inlet (4) for the electrical connection is lo-
cated either on the left or right side. The unused opening on the
opposite side is sealed by a blanking plug. The protective earth
connection is located on the rear of the housing.
The electrical connections for the power supply and screen are
accessible by unscrewing the rear cover. The bottom part of the
housing contains the measuring cell with process connection
(1). The measuring cell is prevented from rotating by a locking
screw (8). As the result of this modular design, the measuring
cell and the electronics can be replaced separately from each
other. The set parameter data are retained.
At the top of the housing is a plastic cover (5), which hides the
input keys.

Function
Operation of the electronics with PROFIBUS PA communica-
tion
Function diagram of the electronics
The bridge output voltage created by the sensor (1, Figure
"Function diagram of the electronics") is amplified by the instru-
ment amplifier (2) and digitized in the analog-to-digital converter
(3). The digital information is evaluated in a microcontroller, its
linearity and temperature response corrected, and converted in
a digital-to-analog converter (5) into an output current of 4 to
20 mA.
The diode circuit (10) protects against incorrect polarity.
The data specific to the measuring cell, the electronics data, and
the parameter data are stored in the two non-volatile memories
(6). The one memory is coupled to the measuring cell, the other
to the electronics. As the result of this modular design, the elec-
tronics and the measuring cell can be replaced separately from
each other.
Using the 3 input keys (8) you can parameterize the pressure
transmitter directly at the point of measurement. The input keys
can also be used to control the view of the results, the error mes-
sages and the operating modes on the digital display (9).
The HART modem (7) permits parameterization using a protocol
according to the HART specification.
The pressure transmitters with spans 63 bar measure the input
pressure compared to atmosphere, transmitters with spans
160 bar compared to vacuum.
Operation of the electronics with PROFIBUS PA communica-
tion
Function diagram of the electronics
The bridge output voltage created by the sensor (1, Figure
"Function diagram of the electronics") is amplified by the instru-
ment amplifier (2) and digitized in the analog-to-digital converter
(3). The digital information is evaluated in the microcontroller, its
linearity and temperature response corrected, and provided on
the PROFIBUS PA through an electrically isolated PA interface
(7).
The data specific to the measuring cell, the electronics data, and
the parameter data are stored in the two non-volatile memories
(6). The first memory is linked with the measuring cell, the sec-
ond with the electronics. This modular design means that the
electronics and the measuring cell can be replaced separately
from one another.
Using the three input keys (8) you can parameterize the pressure
transmitter directly at the point of measurement. The input keys
can also be used to control the view of the results, the error mes-
sages and the operating modes on the digital display (9).
The results with status values and diagnostic values are trans-
ferred by cyclic data transmission on the PROFIBUS PA. Param-
eterization data and error messages are transferred by acyclic
data transmission. Special software such as SIMATIC PDM is re-
quired for this.

Mode of operation of the FOUNDATION Fieldbus electronics
Function diagram of the electronics
The bridge output voltage created by the sensor (1, Figure
"Function diagram of the electronics") is amplified by the instru-
ment amplifier (2) and digitized in the analog-to-digital converter
(3). The digital information is evaluated in the microcontroller, its
linearity and temperature response corrected, and provided on
the FOUNDATION Fieldbus through an electrically isolated
FOUNDATION Fieldbus Interface (7).
The data specific to the measuring cell, the electronics data, and
the parameter data are stored in the two non-volatile memories
(6). The one memory is coupled to the measuring cell, the other
to the electronics. As the result of this modular design, the elec-
tronics and the measuring cell can be replaced separately from

Using the three input keys (8) you can parameterize the pressure
transmitter directly at the point of measurement. The input keys
can also be used to control the view of the results, the error mes-
sages and the operating modes on the digital display (9).
The results with status values and diagnostic values are trans-
ferred by cyclic data transmission on the FOUNDATION
Fieldbus. Parameterization data and error messages are trans-
ferred by acyclic data transmission. Special software such as
National Instruments Configurator is required for this.
Mode of operation of the measuring cells
Measuring cell for gage pressure
Measuring cell for gage pressure, function diagram
The pressure pe is applied through the process connection (2,
Figure "Measuring cell for gage pressure, function diagram) to
the measuring cell (1). This pressure is subsequently transmitted
further through the seal diaphragm (3) and the filling liquid (4) to
the silicon pressure sensor (5) whose measuring diaphragm is
then flexed. This changes the resistance of the four piezo-resis-
tors fitted in the diaphragm in a bridge circuit. This change in re-
sistance results in a bridge output voltage proportional to the in-
put pressure.

Measuring cell for absolute pressure from gage pressure series
Measuring cell for absolute pressure from the pressure series, function
diagram
The absolute pressure pe is transmitted through the seal dia-
phragm (3, Figure "Measuring cell for absolute pressure from the
gage pressure series, function diagram") and the filling liquid (4)
to the silicon absolute pressure sensor (5) whose measuring di-
aphragm is then flexed. This changes the resistance of the four
piezo-resistors fitted in the diaphragm in a bridge circuit. This
change in resistance results in a bridge output voltage propor-
tional to the input pressure.
Measuring cell for absolute pressure from differential pressure
series
Measuring cell for absolute pressure from differential pressure series,
function diagram
The input pressure pe is transmitted through the seal diaphragm
(6, Figure "Measuring cell for absolute pressure from differential
pressure series, function diagram") and the filling liquid (8) to the
silicon pressure sensor (3).
The difference in pressure between the input pressure pe and
the reference vacuum (1) on the low-pressure side of the mea-
suring cell flexes the measuring diaphragm. The resistance of
the four piezo-resistors fitted in the diaphragm in a bridge circuit
thus changes. This change in resistance results in a bridge out-
put voltage proportional to the absolute pressure.
An overload diaphragm is installed to provide protection from
overloads. If the measuring limits are exceeded, the overload di-
aphragm (2) is flexed until the seal diaphragm rests on the body
of the measuring cell (7), thus protecting the silicon pressure
sensor from overloads.
Measuring cell for differential pressure and flow
Measuring cell for differential pressure and flow, function diagram
The differential pressure is transmitted through the seal dia-
phragms (1, Figure "Measuring cell for differential pressure and
flow, function diagram") and the filling liquid (7) to the silicon
pressure sensor (4).
The measuring diaphragm is flexed by the applied differential
pressure. This changes the resistance of the four piezo-resistors
fitted in the diaphragm in a bridge circuit. This change in resis-
tance results in a bridge output voltage proportional to the abso-
lute pressure.
An overload diaphragm is installed to provide protection from
overloads. If the measuring limits are exceeded, the overload di-
aphragm (2) is flexed until the seal diaphragm rests on the body
of the measuring cell (7), thus protecting the silicon pressure
sensor from overloads.
Measuring cell for level
Measuring cell for level, function diagram
The input pressure (hydrostatic pressure) acts hydraulically on
the measuring cell through the seal diaphragm on the mounting
flange (2, Figure "Measuring cell for level, function diagram").
This differential pressure is subsequently transmitted further
through the measuring cell (3) and the filling liquid (9) to the sil-
icon pressure sensor (6) whose measuring diaphragm is then
flexed.
This changes the resistance of the four piezo-resistors fitted in
the diaphragm in a bridge circuit.
This change in resistance results in a bridge output voltage pro-
portional to the differential pressure.

of the measuring cell (7), thus protecting the silicon pressure
sensor from overloads.
Parameterization DS III
Depending on the version, there are a range of options for pa-
rameterizing the pressure transmitter and for setting or scanning
the parameters.
Parameterization using the input keys (local operation)
With the input keys you can easily set the most important param-
eters without any additional equipment.
Parameterization using HART communication
Parameterization using HART communication is performed with
a HART communicator or a PC.
Communication between a HART communicator and a pressure transm.
When parameterizing with the HART communicator, the connec-
tion is made directly to the 2-wire system.
HART communication between a PC communicator and a pressure
transmitter
When parameterizing with a PC, the connection is made through
a HART modem.
The signals needed for communication in conformity with the
HART 5.x or 6.x protocols are superimposed on the output cur-
rent using the Frequency Shift Keying (FSK) method.

Parameterization through PROFIBUS PA interface
Fully digital communication through PROFIBUS PA, profile 3.0, is
particularly user-friendly. The PROFIBUS puts the DS III PA is in
connection with a process control system, e.g. SIMATIC PSC 7.
Communication is possible even in a potentially explosive envi-
ronment.
For parameterization through PROFIBUS you need suitable soft-
ware, e.g. SIMATIC PDM (Process Device Manager).
Parameterization through FOUNDATION Fieldbus Interface
Fully digital communication through FOUNDATION Fieldbus is
particularly user-friendly. Through the FOUNDATION Fieldbus
the DS III FF is connected to a process control system. Commu-
nication is possible even in a potentially explosive environment.
For parameterization through the FOUNDATION Fieldbus you
need suitable software, e.g. National Instruments Configurator.

Overview
SITRANS P pressure transmitter with supplementary electronics for 4-
wire connection
Direct connection of the supplementary electronics to a
SITRANS P pressure transmitter from the DS III HART series pro-
duces a transmitter for four-wire connection.
The supplementary electronics cannot be attached to explosion-
protected pressure transmitters. The supplementary electronics
is fitted in a light metal housing which is mounted on the left side
of the pressure transmitter.
Note on ordering:
The supplementary electronics has to be be ordered through the
supplementary options of the pressure transmitter in question.

SITRANS P measuring instruments for pressure
SITRANS P Accessories
Factory-mounting of valve manifolds on
SITRANS P transmitters
2/142 Siemens FI 01 · 2009
2
Overview
SITRANS P transmitters
P300 for relative and absolute pressure,
DS III for relative and absolute pressure (both designs) and
DS III for differential pressure
can be delivered factory-fitted with the following valve manifolds:
7MF9011-4EA and 7MF9011-4FA valve manifolds for relative
pressure and absolute pressure transmitters
7MF9411-5BA and 7MF9411-5CA valve manifolds for abso-
lute pressure and differential pressure transmitters
Design
The 7MF9011-4EA valve manifolds are sealed with gaskets
made of PTFE between transmitter and the valve manifold as
standard. Soft iron, stainless steel and copper gaskets are also
available for sealing purposes if preferred.
The 7MF9011-4FA valve manifolds are sealed with PTFE sealing
tape between the transmitter and the valve manifold.
The 7MF9411-5BA and 7MF9411-5CA valve manifolds are
sealed with PTFE sealing rings between the transmitter and the
valve manifold.
Once installed, the complete unit is checked under pressure for
leaks and is certified leak-proof with a factory certificate to
EN 10204 - 2.2.
All valve manifolds should preferably be secured with the re-
spective mounting brackets. The transmitters are mounted on
the valve manifold and not on the unit itself.
If you order a mounting bracket when choosing the option "Fac-
tory mounting of valve manifolds", you will receive a mounting
bracket for the valve manifold instead of a bracket for mounting
the transmitter.
If you order an acceptance test certificate 3.1 to EN10204 when
choosing the option "Factory mounting of valve manifolds", a
separate certificate is provided for the transmitters and the valve
manifolds respectively.

SITRANS P measuring instruments for pressure
Transmitters for hydrostatic level
MPS series (submersible sensor)
2/146 Siemens FI 01 · 2009
2
Overview
SITRANS P pressure transmitters, MPS series (submersible sensor)
SITRANS P pressure transmitters, MPS series, are submersible
sensors for hydrostatic level measurements.
The pressure transmitters of the MPS series are available for var-
ious measuring ranges and with explosion protection as an op-
tion.
A junction box and a cable hanger are available as accessories
for simple installation.
Benefits
Compact design
Simple installation
Small error in measurement (0.3%)
Degree of protection IP68
Application
SITRANS P pressure transmitters, MPS series, are used in the
following branches for example:
Oil and gas industries
• Shipbuilding
Water supply
Design
SITRANS P pressure transmitters, MPS series, have a flush-
mounted piezo-resistive sensor with stainless steel diaphragm.
These pressure transmitters are equipped with an electronic cir-
cuit fitted together with the sensor in a stainless steel housing.
The cable also contains a strength cord and vent pipe.
The diaphragm is protected against external influences by a
protective cap.
The sensor, electronic circuit and cable are sealed in a common
housing of small dimensions.
The pressure transmitter is temperature-compensated for a wide
temperature range.
Function
SITRANS P pressure transmitters, MPS series, are for measuring
the liquid levels in wells, tanks, channels and dams.
SITRANS P pressure transmitters, MPS series, mode of operation and
wiring diagram
On one side of the sensor, the diaphragm is exposed to the hy-
drostatic pressure which is proportional to the submersion
depth. This pressure is compared with atmospheric pressure.
Pressure compensation is carried out using the vent pipe in the
connection cable.
The hydrostatic pressure of the liquid column acts on the sensor
diaphragm, and transmits the pressure to the piezo-resistive
bridge in the sensor.
The output voltage of the sensor is applied to the electronic cir-
cuit where it is converted into an output current of 4 to 20 mA.
The cable of the 7MF1570 transmitter must always be connected
in the supplied junction box. The junction box has to be installed
near the measuring point.
If the medium is anything other than water, it is also necessary to
check compatibility with the specified materials of the transmit-
ter.

Remote seals for transmitters and pressure gages
Technical description
2/150 Siemens FI 01 · 2009

Overview
In many cases the pressure transmitter and the measured me-
dium have to be physically separated. It is then necessary to use
a remote seal.
The remote seals can be used with the following SITRANS P
pressure transmitter series:
Pressure (P300, DS III, DS III PA, DS III FF)
Absolute pressure (P300, DS III, DS III PA, DS III FF)
Differential pressure and flow (DS III, DS III PA, DS III FF)
Note
When configuring your remote seal, be sure to read the informa-
tion about transmission response, temperature error and re-
sponse time to be found in the sections "Function" and "Technical
data". Only then will the remote seal work to optimum effect.
Benefits
No direct contact between the pressure transmitter and the
medium
Individual configuration of the pressure transmitter for perfect
adaptation to the operating conditions
Available in many versions
Specially designed for difficult operating conditions
Quick-release versions available for the food industry
Application
Remote seal systems should be used if a separation between
the measured medium and the measuring instrument is essential
or appropriate.
Examples of such cases:
The temperature of the medium is outside the limits specified
for the pressure transmitter.
The medium is corrosive and requires diaphragm materials
which are not available for the pressure transmitter.
The medium is highly viscous or contains solids which would
Siemens FI 01 · 2009block the measuring chambers of the
pressure transmitter.
The medium may freeze in the measuring chambers or pulse
line.
The medium is heterogeneous or fibrous.
The medium tends towards polymerization or crystallization.
The process requires quick-release remote seals, as neces-
sary e.g. in the food industry for fast cleaning.
The process requires cleaning of the measuring point, e.g. in
a batch process.
Design
A remote seal system consists of the following components.
Pressure transmitter
One or two remote seals
Filling liquid
Connection between pressure transmitter and remote seal (di-
rect mounting or by means of capillary)
The volume in contact with the measured medium is terminated
by a flat elastic diaphragm lying in a bed. Between the dia-
phragm and the pressure transmitter is the filling liquid.
In many cases, a capillary has to be connected between the re-
mote seal and the pressure transmitter in order e.g. to minimize
temperature effects on the latter when hot media are involved.
However, the capillary influences the response time and the tem-
perature response of the complete remote seal system. Two
capillaries of equal length must always be used to connect a re-
mote seal to a pressure transmitter for differential pressure.
The remote seal can be optionally equipped with a projecting di-
aphragm (tube).
Remote seals of sandwich design are fitted with a dummy
flange.
Designs
Diaphragm seal
With diaphragm seals, the pressure is measured by means of a
flat diaphragm which rests in a bed.
The following types of diaphragm seals exist:
Diaphragm seal of sandwich design without (left) and with a projecting
diaphragm (tube)
Sandwich design
Sandwich design with projecting diaphragm (tube) to DIN or
ASME which are secured using a dummy flange.
Diaphragm seal of flange design without (left) and with a projecting dia-
phragm (tube)
Flange design
Flange design with projecting diaphragm (tube) to DIN or
ASME, secured using holes in the flange.
Quick-release diaphragm seal
Quick-release remote seals, e.g. to DIN 11851, SMS standard,
IDF standard, APV RJT standard, clamp connection, etc.

Miniature diaphragm seals
The quick-release remote seals are used above all in the food in-
dustry. Their design means that the measured medium cannot
accumulate in dead volumes. The quick-release clamp present
on the remote seal means that quick dismounting is possible for
cleaning.
Clamp-on seal
Clamp-on seal with quick-release design (left) and for flange mounting
With clamp-on seals, the pressure is first measured using a cy-
lindrical diaphragm positioned in a pipe, and then transmitted to
the pressure transmitter by means of the filling liquid.
The clamp-on seal is a special design for flowing media. It con-
sists of a cylindrical pipe in which a cylindrical diaphragm is em-
bedded. Since it is completely integrated in the process pipe, no
turbulences, dead volumes or other obstructions to the flow oc-
cur. Furthermore, the clamp-on seal can be cleaned by a pig.
The following types of clamp-on seals exist:
Quick-release clamp-on seals, e.g. to DIN 11851, SMS stan-
dard, IDF standard, APV/RJT standard, clamp connection etc.
The quick-release facility attached to the remote seal enables
the seal to be removed quickly for cleaning purposes.
Clamp-on seals for flanging to EN or ASME.
Clamp-on seals with customer-specific process connections.
Note:
The pressure data on the transmitter and the remote seal must
be observed with regard to pressure/temperature behavior.
Function
The measured pressure is transferred from the diaphragm to the
filling liquid and passes through the capillary to the measuring
chamber of the pressure transmitter. The interior of the dia-
phragm seal and of the capillary, as well as the measuring cham-
ber of the transmitter, are filled gas-free by the filling liquid.
Transmission response
The transmission response of a remote seal is characterized by
the following variables:
Temperature error
Adjustment time
Temperature error
Temperature errors are caused by the change of volume of the
filling liquid due to temperature variations. To select the right re-
mote seal you must calculate the temperature error.
Below you will find an overview of the factors which influence the
size of the temperature error, as well as information on how to
calculate the temperature error.
The temperature error is dependent on the following variables:
Rigidity of the diaphragm used
Filling liquid used
Influence of the filling liquid underneath the process flanges or
in the connection shank of the pressure transmitter
Internal diameter of the capillary: The bigger the internal diam-
eter, the bigger the temperature error
Length of the capillary: The longer the capillary, the bigger the
temperature error
Diaphragm rigidity
The rigidity of the diaphragm is of decisive importance. The big-
ger the diameter of the diaphragm, the softer the diaphragm and
the more sensitively it reacts to temperature-induced changes in
volume of the filling liquid.
The result is that small measuring ranges are only possible with
large diaphragm diameters.
Other factors apart from diaphragm rigidity which also play a
role:
Diaphragm thickness
Diaphragm material
Coatings if present
Filling liquid
Every filling liquid reacts to temperature variations with a change
of volume. Temperature errors can be minimized by selecting a
suitable filling liquid, but the filling liquid must also be appropri-
ate for the temperature limits and operating pressure. Further-
more, the filling liquid must also be physiologically harmless.
Since the filling liquid is present under the diaphragm, in the
capillary and under the process flange of the pressure transmit-
ter (or in the connection shank), the temperature error must be
calculated separately for each combination.
Note:
When operating in the low-pressure range, also during commis-
sioning, it is recommended to use a vacuum-proof remote seal
(see Selection and Ordering data).
An example of a temperature error calculation can be found in
the section "Technical Specifications".

Response time
The response time is dependent on the following factors:
Internal diameter of the capillary: The bigger the internal diam-
eter, the shorter the response time
Viscosity of the filling liquid The greater the viscosity, the
longer the response time
Length of the capillary: The longer the capillary, the longer the
response time
Pressure in the pressure measuring system: The higher the
pressure, the shorter the response time
Recommendations
The following should be observed to obtain an optimum combi-
nation of transmitter and remote seal:
• Choose the biggest possible diameter for the remote seal. The
effective diameter of the seal diaphragm is then bigger and
the temperature error smaller.
Choose the shortest possible capillary. The response time is
then shorter and the temperature error smaller
Choose the filling liquid with the least viscosity and the small-
est coefficient of expansion. Make sure, however, that the fill-
ing liquid meets the process requirements with regard to pres-
sure, vacuum and temperature. And ensure that the filling
liquid and the medium are compatible with one another.
Note the following points for use in the vacuum range:
- The pressure transmitter must always be positioned below
the lowest spigot.
- The operating range of some filling liquids is very limited with
regard to the permissible temperature of the medium.
- A vacuum-proof seal is necessary for continuous operation
in the low-pressure range.
Recommendations for the minimum span can be found in the
section "Technical data".
Note
The remote seals listed here are a selection of the most common
designs. On account of the large variety of process connections,
certain remote seals which are not listed here may be available
nevertheless.

Calculation of the temperature error
The following equation is used to calculate the temperature er-
ror:
Example of temperature error calculation
Dependence of temperature error on diaphragm material
The temperature errors listed in the previous table are based on
the use of stainless steel as the diaphragm material. If other dia-
phragm materials are used, the temperature errors change as
follows:
Maximum temperature of medium
The following maximum temperatures of the medium apply de-
pending on the material of the wetted parts:
Maximum capillary length for diaphragm seals (guidance
values)
dp = (ϑRSϑCal) fRS + (ϑCapϑCal) lCap fCap + (ϑTRϑCal) fPF
dp Additional temperature error (mbar)
ϑRS Temperature on remote seal diaphragm (generally
corresponds to temperature of medium)
ϑCal Calibration (reference) temperature (20 °C (68 °F))
fRS Temperature error of remote seal
ϑCap Ambient temperature on the capillaries
lCap Capillary length
fCap Temperature error of capillaries
ϑTR Ambient temperature on pressure transmitter
fPF Temperature error of the oil filling in the process
flanges of the pressure transmitter
Existing conditions
SITRANS P pressure transmitter for
differential pressure, 250 mbar, set
to 0 ... 100 mbar, with DN 80 remote
seal diaphragms without tube, dia-
phragm made of stainless steel,
mat. No. 1.4404/316L
fRS = 0.1 mbar/10 K
(0.0014 psi/10 K)
Capillary length lCap = 6 m (19.7 ft)
Capillaries fitted on both sides fCap = 0.07 mbar/(10 K mCap)
(0.001 psi/(10 K mCap))
Filling liquid silicone M5 fPF = 0.07 mbar/10 K
(0.001 psi/10 K)
Process temperature ϑRS = 100 °C (212 °F)
Temperature on the capillaries ϑCap = 50 °C (122 °F)
Temperature on pressure transmit-
ter ϑTR = 50 °C (122 °F)
Calibration temperature ϑCal = 20 °C (68 °F)
Required
Additional temperature error of
remote seals dp
Calculation
in mbar
dp = (100 °C – 20 °C) 0.1 mbar/10 K + (50 °C – 20 °C) 6m
0.07 mbar/(10 K m) + (50 °C – 20 °C) 0.07 mbar/10 K
dp = 0.8 mbar + 1.26 mbar + 0.21 mbar
in psi
dp = (212 °F – 68 °F) 0.0014 psi/10 K + (112 °F – 68 °F) 19.7 ft
0.001 psi/(10 K 3.28 ft) + (112 °F – 68 °F) (0.001 psi/10 K)
dp = 0.012 psi + 0.018 psi + 0.003 psi
Result
dp = 2.27 mbar (0.033 psi) (corresponds to 2.27% of set span)
Note
The determined temperature error only applies to the error resulting
from connection of the remote seal.
The transmission response of the respective transmitter is not included
in this consideration.
It must be calculated separately, and the resulting error added to the
error determined above from connection of the remote seal.

Response times
The values listed in the following table are the response times (in
seconds per meter of capillary) for a change in pressure which
corresponds to the set span.
The listed values must be multiplied by the respective length of
the capillary, or with transmitters for differential pressure and flow
by the total length of both capillaries.
The response times are independent of the set span within the
range of the respective transmitter. The response times are of in-
significant importance for spans above 10 bar (145 psi). The re-
sponse times of the pressure transmitters are not considered in
the table.
Technical data of filling liquids
When selecting the filling liquid, check that it is suitable with re-
spect to the permissible temperature of the medium and the pro-
cess pressure.
Also check the compatibility of the filling liquid with the mea-
sured medium. For example, only physiologically harmless filling
liquids may be used in the food industry.
Oxygen and chlorine are special cases of measured medium.
The liquid must not react with either of these two media or a leak-
ing remote seal may lead to an explosion or fire.

Overview
Quick-release diaphragm seals, to DIN 11851 with slotted union nut
Quick-release diaphragm seals, with clamp connection
Quick-release diaphragm seals are available for the following
SITRANS P pressure transmitter series:
For pressure: MK II, DS III, DS III PA, DS III FF
For differential pressure and flow: DS III, DS III PA, DS III FF
The quick-release remote seals are common designs in the food
industry. Their design means that the measured medium cannot
accumulate in dead volumes. The quick-release clamp present
on the remote seal means that quick dismounting is possible for
cleaning.

Flushing rings
For diaphragm seals
2/174 Siemens FI 01 · 2009
2
Overview
Flushing ring
Flushing rings are required for flange-mounted and sandwich-
type remote seals (Order No. 7MF4900 ... 7MF4923) if the dan-
ger exists that the process conditions and the geometry of the
connection could cause the medium to form deposits or block-
ages.
The flushing ring is clamped between the process flange and
the remote seal.
Deposits can be flushed away from the diaphragm through the
holes in the side, or the pressure volume can be vented. Different
nominal diameters and forms permit adaptation to the respec-
tive process flange.
Process connection
For flanges to EN and ASME:

SITRANS P measuring instruments for pressure
Clamp-on seals of flange design
For gage pressure, differential pressure and flow
2/176 Siemens FI 01 · 2009
2
Overview
Clamp-on seals for flange-mounting
The clamp-on seal is completely integrated in the process line.
It is particularly suitable for flowing and highly viscous media.
The clamp-on remote seal consists of a cylindrical jacket into
which a thin-walled pipe is welded. It is clamped directly be-
tween two flanges in the pipeline.
Design
Clamp-on seals for flange-mounting (flange design) to
EN/ASME for SITRANS P pressure transmitters
- For pressure: P300, DS III, DS III PA and DS III FF series
- For differential pressure and flow: DS III, DS III PA and
DS III FF
Sealing face to EN 1092-1 or ASME B16.5
Connection to the transmitter directly or by means of a flexible
capillary (max. 10 m long)
See Technical data for details of materials used for the wetted
parts
Material used for the capillary, the guard sleeve, the seal’s
main body and the measuring cell: Stainless steel,
mat.-No. 1.4571
Filling liquid: Silicone oil, high-temperature oil, halocarbon oil,
food oil (FDA listed) or glycerin/water (not suitable for uses in
low-pressure range)
Function
The measured pressure is transferred from the diaphragm to the
filling liquid and passes either directly or through the capillary to
the measuring chamber of the pressure transmitter. The interior
of the diaphragm seal and of the capillary, as well as the mea-
suring chamber of the pressure transmitter, are filled gas-free by
the filling liquid.
Note:
When operating in the low-pressure range, also during commis-
sioning, it is recommended to use a vacuum-proof remote seal
(see Selection and Ordering data).

SITRANS P measuring instruments for pressure
Quick-release clamp-on seals
For pressure and absolute pressure
2/179
Siemens FI 01 · 2009
2
Overview
Quick-release clamp-on seals, to DIN 11851 with threaded socket
Quick-release clamp-on seals, with clamp connection
Quick-release clamp-on seals for pressure are available for the
following SITRANS P pressure transmitter series:
• P300
DS III
DS III PA
DS III FF
Application
The quick-release clamp-on seal is a special design for flowing
media and high-viscosity media. Since it is completely inte-
grated in the process pipe, no turbulences, dead volumes or
other obstructions to the flow occur. The measured medium
flows unhindered through the clamp-on seal and results in self-
cleaning of the measuring chamber. Furthermore, the clamp-on
seal can be cleaned by a pig.
Design
The quick-release clamp is available in two versions:
DIN 11851 with threaded socket
Clamp connection
The clamp-on seal is connected to the pressure transmitter ei-
ther directly or by way of a capillary.
Function
The measured pressure is transferred from the diaphragm,
mounted on the inner circumference of the clamp-on seal, to the
filling liquid and then passes through the capillary to the measur-
ing chamber of the pressure transmitter. The interior of the
clamp-on seal and of the capillary, as well as the measuring
chamber of the pressure transmitter, are filled gas-free by the fill-
ing liquid.
Note:
When operating in the low-pressure range, also during commis-
sioning, it is recommended to use a vacuum-proof pressure
transmitter (see Selection and Ordering data).

SITRANS P measuring instruments for pressure
Remote seals
Measuring setups
2/182 Siemens FI 01 · 2009
2
Overview
This section shows examples of typical measuring setups for us-
ing SITRANS P pressure transmitters with and without remote
seals.
Equations for calculating start of scale and full scale are pro-
vided for each example.
Questionnaires are included to help you select the right combi-
nation of remote seal and pressure transmitter.
Installation
Remote seals of sandwich design are fitted between the con-
nection flange of the measuring point and a dummy flange. Re-
mote seals of flange design are fitted directly on the connection
flange of the measuring point. The respective pressure rating of
the dummy flange or the flanged remote seal must be observed.
The pressure transmitter should be installed below the connec-
tion flange (and below the lower connection flange in the case of
differential pressure transmitters). This arrangement must be
used in the low-pressure range.
When measuring at pressures above atmospheric, the pressure
transmitter can also be installed above the connection flange.
The capillaries between the remote seal and the pressure trans-
mitter should be as short as possible to obtain a good transmis-
sion response.
Offset of measuring range
If there is a difference in height between the two connection
flanges when measuring with two remote seals, an additional dif-
ferential pressure will result from the oil filling of the remote seal
capillaries. This results in a measuring range offset which has to
be taken into account when you set the pressure transmitter.
An offset in the measuring range also occurs when combining a
remote seal with a transmitter if the remote seal is not installed at
the same height as the transmitter.
Pressure transmitter output
If the level, separation layer or density increase in closed ves-
sels, the differential pressure and hence the output signal of the
pressure transmitter also increase.
For an inverted relationship between the differential pressure
and the output signal, the start-of-scale and full-scale values of
the SITRANS P must be interchanged.
With open vessels, a rising pressure is usually assigned to an in-
creasing level, separation layer or density.
Influence of ambient temperature
Temperature differences between the individual capillaries and
between the individual remote seals should be avoided.
Temperature variations in the area of the measuring setup cause
a change in volume of the filling liquid and hence measuring er-
rors.
Notes
For the separation layer measurement, the separation layer
has to be positioned between the two spigots. Also you must
make sure that the level in the container is always above the
top spigot.
• When measuring density, make sure that the level of the me-
dium remains constant. The level should be above the top
spigot.

Overview
Notes
For the separation layer measurement, the separation layer
has to be positioned between the two spigots.
Also you must make sure that the level in the container is al-
ways above the top spigot.
• When measuring density, make sure that the level of the me-
dium remains constant. The level should be above the top
spigot

The different pressures and tem-
peratures (densities) in the vessel
and in the reference column result
in an offset in the start-of-scale
and full-scale values.
The calibration data are deter-
mined in addition.
It is also checked whether – as a
result of the range offset – the
ordered transmitter is suitable for
this measurement.
Please supply the following characteristic data so that we can calculate the measuring range,
start-of-scale value, full-scale value and calibration data:
1) Reference line filled with condensation! Falling differential pressure with increasing level.
2) Reference line without gas or filled with gas (air). Rising differential pressure with increasing level.
3) If not specified otherwise, this value is assumed as the calculation pressure of the level meter.
The input signal (differential pressure) depends on the density (pressure and temperature).
The influence is practically negligible for a lowest liquid level of 20 to 30% of the distance between the
measuring points.
4) If a pressure correction of the level is required, the measuring range must be the same as the
distance between the measuring points, and the transmitter is designed for the calculation pressure
of 1 bar (absolute).
Pressure correction means: the static pressure and the temperature are measured separately and
calculated by a correction computer or measured-value computer.

Technical description

Overview
All 21-off fittings can be secured onto walls, racks (72 mm grid)
and vertical and horizontal pipes.
This offers the advantage when assembling a plant that the shut-
off fittings can be secured first and the lines for the medium and
differential pressure connected to them. It is then possible to
check all connections for leaks and to blow out or flush the pipes
in order to remove dirt (welding residues, shavings etc.).
The measuring instruments can be screwed onto the shut-off fit-
tings right at the end when all piping has been completed.
If an instrument has to be removed for maintenance, the fittings
and pipes remain as they are. It is only necessary to close the
valves – the instrument can then be removed, and refitted follow-
ing maintenance.
Classification according to pressure equipment directive
(DGRL 97/23/EC):
For gases of fluid group 1 and liquids of fluid group 1; compli-
ance with requirements of article 3, paragraph 3 (sound engi-
neering practice).Siemens FI 01 · 2009
New standard DIN EN 61518
The flange connection between transmitter and valve manifold
was modified in the new standard DIN EN 61518. The only con-
nection thread approved for use in the process flanges of the
pressure transmitter is 7/16-20 UNF.
The valve manifolds for M12 screws, including the accessory
sets, have therefore been deleted.
Material acceptance test certificate to EN 10204-3.1
If a material acceptance test certificate to EN 10204-3.1 is re-
quired when ordering valve manifolds or shut-off fittings, please
note that a single certificate is sufficient for each ordered item
type. This means that you will only be charged for one certificate
in the cost calculations.

Overview
Transmitter for pressure with double shut-off valve 7MF9401-...
The shut-off valves for pressure gages are used to shut off the
line of the measured medium when dealing with aggressive and
non-aggressive gases, vapors and liquids.
Design
A water trap must be connected upstream of the shut-off valve
in the case of temperatures of the medium above 120 °C. The
shut-off valves form B have a shaft with which they can be se-
cured on an instrument bracket. An adapter is therefore not re-
quired to secure these valves. The vent/test connection can be
shut off separately with the double shut-off valves DN 5. This per-
mits checking of the zero on the pressure gage. In addition, the
characteristic of the pressure gage can be checked using an ex-
ternal pressure source.

Water traps, Sealing rings to EN 837-1
2/228 Siemens FI 01 · 2009
2
Overview
Water traps protect pressure gages and shut-off fittings from
heating up (e.g. by steam) by the water column produced by the
water trap.
The max. working temperature is 120 °C at 160 bar, 300 °C at
80 bar or 400 °C at 63 bar. If the temperature of the measured
medium is higher, a sufficiently long line has to be connected up-
stream of the trap to enable heat dissipation.
Design
The water traps are available in U shape (type B) or circular
shape (type D) to DIN 16282. They have a weld-on end
Ø 20 mm × 2.6 mm on the measurement side. The connection
on the device side is a clamping sleeve G½ to DIN 16283.
The water traps are made of steel (P250GH) or stainless steel
(X 6 CrNiMoTi 17 12 2)
Water traps are designed as standard for max. operating tem-
perature 120 °C at max. operating pressure 160 bar (300 °C at
80 bar, 400 °C at 63 bar). Water traps for higher operating pres-
sures and temperatures are available on request.

Pressure surge reducers
2/229
Siemens FI 01 · 2009
2
Overview
The pressure surge reducer protects the pressure gage against
damage, premature wear and tear and inaccurate/fluctuating in-
dications.
Application
The pressure reducer is used when pulsations occur in the mea-
sured medium (e.g. in slow-running vapor engines, piston
pumps and compressors), or if drastic fluctuations are likely to
occur in the measured medium (e.g. in hydraulic presses and
tensile testing machines).

Overview
The compensation vessels prevent the level difference which oc-
curs with pressure changes in the pressure lines and which fal-
sifies the measurement.
According to DIN 19211, the temperature in the compensation
vessel must be assumed to be 50 K less than the steam temper-
ature in the pipe when calculating the wall thicknesses. This is
because the temperature in the compensation vessel during op-
eration can only rise up to the saturated steam temperature.
A material acceptance test certificate A to EN 10204-3.1 is avail-
able for the materials from which the compensation vessels are
made.
