Temperature-76
The Rosemount® Model 244E is a cost-efficient solution for non-critical temperature monitoring applications.
Compared to wiring direct, the Model 244E will save money in cabling and installation costs while delivering
accurate and reliable measurement.
INSTALLATION READY SOLUTIONS
The Model 244E is part of the Rosemount Complete
Point Solutions (CPS) program. CPS guarantees that
the transmitter, sensor, extension, and thermowell
will be shipped from the factory as an installation
ready assembly to save on installation costs.
FLEXIBILITY
The Model 244E allows for great flexibility in
selecting a sensor type that is appropriate for the
process being measured. The Model 244E accepts
inputs from a wide variety of 2-, 3-, and 4-wire
RTDs as well as thermocouples, millivolt, and ohm
sensor types.
ISOLATION
The Model 244E is designed with 500 VAC input to
output isolation. This isolation helps to ensure the
integrity of the temperature measurement in
industrial environments and not damage sensitive
system electronics.
PROGRAMMABLE
The Model 244EC Configuration Interface consists
of a programmer, cables, and configuration software.
The Model 244EE configuration software, when used
in conjunction with the interface, provides the tools
necessary to select the sensor type, sensor range,
and sensor error action in addition to many
other options.
UNIVERSAL HEAD
The Model 244EH head mount transmitter offers
different configurations for mounting. Using the
Rosemount Universal Head, the Model 244EH
may be mounted either integrally or remotely to
fit the needs of the specific temperature monitoring
application.

FUNCTIONAL SPECIFICATIONS
Inputs
User-selectable using the Model 244EC Configuration Interface
and the Model 244EC Configuration Software. Sensor terminals
are rated to 42.4 V dc. See “Accuracy”.
Output
2-wire 4–20 mA, linear with temperature for RTDs and
thermocouples and linear with input for millivolts and ohms.
Isolation
Input/output isolation tested to 500 V ac rms (707 V dc) at 50/60
Hz
Power Supply
An external power supply is required. The transmitter operates on
12.0 to 42.4 V dc. Transmitter power terminals are rated to
42.4 V dc.
Failure Mode
The Model 244E features software driven alarm diagnostics and
an independent circuit. These features are designed to provide
backup alarm outputs in case the microprocessor, electronics,
hardware, or software fails. The alarm levels are user-selectable
using the failure mode switch. In case of alarm, the position of the
jumper determines the direction in which the output is driven (HI or
LO). The jumper switch feeds into the digital-to-analog (D/A)
converter, which drives the proper alarm output even if the
microprocessor fails. The values that the transmitter drives its
output in failure mode depends on whether it is factory configured
to standard or NAMUR compliant operation. The values for
standard and NAMUR-compliant operation are as follows.

Rosemount Conformance to Specifications
You can be confident that a Rosemount product not only meets its published
specifications, but most likely exceeds them. Our advanced manufacturing techniques
and use of Statistical Process Control provide specification conformance to at least
±3(1). In addition, our commitment to continual improvement ensures that product
design, reliability, and performance will improve every year.
For example, the Reference Accuracy distribution for the Model 244E Temperature
Transmitter is shown to the right. Our Specification Limits are ± 0.2 °C, but, as the
shaded area shows, approximately 68% of the units perform three times better than
the limits. Therefore, it is very likely that you will receive a device that performs much
better than our published specifications.
Conversely, a vendor who “grades” product without using Process Control, or who is
not committed to ± 3 performance, will ship a much higher percentage of units that
are barely within (or even outside of) advertised specification limits.
Note: Accuracy distribution shown is for Model 244E,
Pt 100 RTD sensor, range 0 to 100 °C.
(1) Sigma (s) is a statistical symbol to designate the standard deviation from the mean value of a normal distribution.

TABLE 2. Accuracy/Input Options
Accuracy Example
When using a Pt 100 (a = 0.00385) sensor input with a 75 to 150
°C range, the accuracy will be ±0.15 °C of span + 0.15 °C or
0.2 °C, whichever is greater. Sample Calculation: [0.0005
(150-75)+0.15] = 0.19 °C, whichever is less than 0.2 °C, so the
accuracy equals 0.2.

Ambient Temperature Effect
Transmitters can be installed in locations where the ambient
temperature is between –40 and 85 °C (–40 and 185 °F). To
maintain excellent accuracy performance, each transmitter is
individually characterized over this ambient temperature range at
the factory. The transmitters automatically adjust for component
temperature drift caused by changing environmental conditions.
TABLE 3. Ambient Temperature Effects
Temperature Effects Example
Example 1:
When using a Type J thermocouple with a 50 °C to 600 °C
temperature range at an ambient temperature of 60 °C and a
reading of –25 °C, the ambient temperature effect according to °C
is:
• [fixed value (a) + (% of reading (b) x reading) = (% of span (c)
x span)] = [0.006 + (–0.000025 x (–25)) + (0.00001 x 650)] =
0.013 °C per °C.
With the ambient temperature 40 °C above reference condition
temperature, the total ambient temperature effect is:
• 40 x 0.013 = 0.52 °C
Example 2:
When using a Type J thermocouple with a – 50 °C to 600 °C
temperature range at an ambient temperature of 60 °C and a
reading of 525 °C, the ambient temperature effect according to °C
is:
• [fixed value (a) + (% of reading (b) x reading) = (% of span (c)
x span)] = [0.006 + (–0.0000054 x 525) + (0.00001 x 650)] =
0.015 °C per °C.
With the ambient temperature 40 °C above reference condition
temperature, the total ambient temperature effect is:
• 40 x 0.015 = 0.6 °C
Example 3:
The worst case error would be:
• Reference Accuracy + CJC Accuracy + Temp Effects = 0.65
°C + 0.5 °C + 0.52 °C = 1.67 °C.
Total probably error:

Hardware Tag
• No charge
• Tagged in accordance with customer requirements
• Tags are adhesive labels
• Permanently attached to transmitter
• Character height is
1/16-in (1.6 mm)
Software Tag
• The transmitter can store up to 8 characters in its memory
• Transmitter can be ordered with different software and
hardware tags
• If the software tag characters are not specified, the software
tag will default to the first 30 characters of the hardware tag.
Special Mounting Considerations
Special mounting hardware is available for:
• Mounting a Model 244EH to a DIN rail. See “Mounting”.
• Retrofitting a new Model 244EH to replace an existing Model
244EH transmitter in an existing threaded sensor connection
head. See “Mounting”.
External Ground Screw Assembly
The external ground screw assembly can be ordered by specifying
option code G1 when an enclosure is specified. However, some
approvals include the ground screw assembly in the transmitter
shipment, hence it is not necessary to order option code G1. See
below to determine which approval options include the external
ground screw assembly.

Configuration
Unless specified, the transmitter will be shipped as follows:
Custom Configuration
The transmitter can be ordered with custom configuration. Use the
following table to determine the requirements when specifying the
custom configuration.
Configuration Software
The PC-based configuration software for the Models 244EH and
244ER allow comprehensive configuration of the transmitters.
Used in conjunction with a Model 244EC Configuration Interface,
the software provides the tools necessary to configure and view
the process variable of a Model 244EH or Model 244ER.
Using the software, the following parameters are available:
• Process Variable
• Sensor type
• Number of Wires
• 50/60 Hz selection
• Engineering Units
• Upper and lower range values
• Damping value
• Transmitter electronic tag
Software for the Model 244EC is available in English, French,
German, Italian, Spanish, Chinese, Japanese, and Korean. A
spreadsheet for printing labels and one sheet of labels are
included with the software. The labels can be used when the
transmitter configuration has been changed. The user can place a
new label on the transmitter to reflect the new configuration
parameter.
Model 244EC Configuration Interface
The Model 244EC Configuration interface is a portable,
self-contained communication link between your PC and
transmitter.
The Model 244EC connects to the serial port on your PC with a
standard 9-pin interconnecting plug and to a transmitter using two
MINIGRABBER™ clips. Power is provided by one replaceable
9-volt battery. The Model 244EC will also operate using a wall
power adapter.
The Model 244EC is approved for Factory Mutual (FM) and
Canadian Standards Association (CSA) Ordinary Locations.
