SITRANS LR260
SITRANS LR260 Overview
SITRANS LR260 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring
of solids and liquids in storage vessels including extreme levels of dust and high
temperatures, to a range of 30 m (98.4 ft).
The instrument consists of an electronic component coupled to a horn antenna with an
integral Easy Aimer and flange or threaded connection for quick and easy positioning. A
dust cover or air purging are available as options.
SITRANS LR260 supports HART1) communication protocol, and SIMATIC PDM software.
Signals are processed using Process Intelligence which has been field-proven in over
1,000,000 applications worldwide (ultrasonic and radar).
Programming
SITRANS LR260 is very easy to install and configure via a graphical local user interface
(LUI). You can modify the built-in parameters either locally via the Siemens infrared
handheld programmer, or from a remote location via SIMATIC PDM.
Applications
• cement powder, plastic powder/pellets, grain, flour, coal, and other applications
• solids and liquids bulk storage vessels
Approvals and Certificates
SITRANS LR260 is available with General Purpose approval, or for Hazardous areas. For

Installation
Air Purging System (Optional)
For more frequent cleaning, a purging system can be installed between the flange and the
horn antenna. The system provides an 1/8" inlet (female thread) on the flange where
cooling air or cleaning fluid passes through the flange and exits the inside of the horn to
clean it. The customer will supply the purging medium by a manual or automatic valve
system.
This option is only available with the universal flange for purging shown on page 18. 1)
• The purge connection is closed
by the manufacturer, using a 1/8"
plug.
• When the plug is removed to
connect a purging system, the
operator is responsible for
ensuring that the purging circuit
conforms to "Ex" requirements:
for example, by fitting an NRV
valve. 2) 3)
Notes:
• The Air Purge feature should not be activated with a dust cap in place.
• Purge duration, pressure, and interval, will vary with each application. It is the user’s
responsibility to determine the requirements depending on the application and
cleaning required.
• Short duration bursts of high pressure provide more effective cleaning than
continuous low pressure air.
• Some dust particles are highly abrasive and can be drawn into the inside of the horn
during purge cleaning, damaging the internal PTFE emitter of the antenna. A
replacement kit is available from your local Siemens Milltronics representative.
• It is the customer’s responsibility to ensure that any vacuum or pressure in the
measured vessel is maintained, considering the hole that passes through the
process connection and SITRANS LR260 antenna system.

Installation
Dust Cap (Optional)
The dust cap fits onto the end of the horn and prevents the buildup of dust and other
process material inside the horn.
• It is particularly useful for applications in areas of high humidity, or with bulk solids
with a high moisture content.
• Three sizes are available, to fit the standard 2", 3" and 4" horns.
Installation
1. Thoroughly clean inside the horn. If you remove the horn for easier cleaning, take
care not to damage or bend the plastic emitter.
2. Press the cap firmly onto the horn until the ridge inside the cap snaps into position in
the groove on the outside of the horn.
3. Hand tighten the adjustable clamp supplied to secure the cap.
4. Use a screwdriver or nut driver to tighten the clamp screw until the clamp provides
an air-tight seal.
Note: The dust cap must be removed before using the Air Purge feature (see
Air

Passive Shunt Diode Barriers
How to select a passive barrier for SITRANS LR260
To make sure that the barrier safety description is suitable for the LR260 Intrinsically Safe
(IS) input parameters, carry out the following calculations:
Re-e = max. end-to-end resistance of the barrier
Rloop = loop resistance (total of cable resistance plus any additional series
resistance, for example, PLC inputs and/or displays)
Vbarrier = value of any non-linear voltage drops due to the barrier
1) Determine the value for Re-e from the data sheet.
2) Calculate the total value for Rloop.
3) Calculate Rworking = Re-e + Rloop.
4) Determine the value of Vbarrier from the barrier data sheet (for example, voltage
drops due to diodes).
5) Calculate Vworking = Vsupply – Vbarrier.
Use the values for Vworking and Rworking to confirm that operation is within the
shaded area of the graph

Auto False Echo Suppression
SITRANS LR260 first learns the echo profile. Then the learned profile, or part of it, is used to
screen out false echoes. (See
Auto False Echo Suppression
on page 98 for a more detailed
explanation.)
1. Determine Auto Suppression Range (the distance within which the learned TVT will
replace the default TVT). Measure the actual distance from the antenna reference
point to the material surface using a rope or tape measure, and make allowances
for the actual location of the LR260. Subtract 2 m (6.56 ft) from this distance, and use
the resulting value.
2. Open the menu Device – Auto False Echo Suppression.
3. Enter the value for Auto Suppression Range and click on Set Range.
4. Click on Learn. While the new curve is being learned, all buttons are inaccessible.
Unless calculation is instantaneous, buttons will disappear until it is complete.
5. When buttons are visible, click on Close. Auto TVT is now on, and the learned TVT
curve will be used.
6. To turn Auto False Echo Suppression off or on, reopen menu Device – Auto False
Echo Suppression and click on Off or On.
Notes:
• If possible, adjust Auto False Echo Suppression parameters with an empty or almost
empty vessel.
• Set Auto False Echo Suppression and Auto Suppression Range during startup, if
possible.
• Before adjusting these parameters, rotate the instrument for best signal (lower
false-echo amplitude).

of the learned profile, is used to screen out false echoes. See Before and After
Auto False Echo Suppression on page 60 for examples.
2.2.5.1. TVT Hover Level
Defines how high the TVT (Time Varying Threshold) curve is placed above
the noise floor of the echo profile, as a percentage of the difference between
the peak of the largest echo in the profile and the noise floor. When
SITRANS LR260 is located in the center of the vessel, the TVT hover level
may be lowered to increase the confidence level of the largest echo.
(For an
illustration of the TVT curve see
Before Auto False Echo Suppression on
page 60.)

Appendix B: Troubleshooting
Communication Troubleshooting
Generally:
1. Check the following:
• There is power at the instrument
• The LCD shows the relevant data you are expecting
• The device can be programmed using the hand programmer
2. Verify that the wiring connections are correct.
3. Check that the device address is correctly set.
4. If you continue to experience problems, go to our website at:
. www.siemens.com/processautomation, and check the FAQs for SITRANS LR260, or
contact your local Siemens Milltronics representative.
Specifically:
1. If you try to set a SITRANS LR260 parameter via remote communications, but the
parameter remains unchanged:
• Some parameters can only be changed when the device is not scanning. Try
putting the device in PROGRAM mode using the operating mode function.
• Try setting the parameter from the keypad. (First make sure that the lock
parameter [6.1] is set to the unlock value.)
• The communications control parameter 5.2 must be set to Read/Write to allow
you to write parameters to SITRANS LR260.
2. If you see unanticipated displays, for example:
• PROGRAM mode displayed instead of Measurement mode
• the wrong parameter displayed in response to a command
• a parameter displayed in response to no command
make sure no infrared-capable device is close to SITRANS LR260. Any device with
infrared capabilities (laptops, cell phones, PDAs) can cause interference which
simulates a command to the SITRANS LR260, potentially causing it to switch modes
or to change a parameter.
3. If the operation is erratic, make sure the Hand Programmer is not being used at the
same time as SIMATIC PDM.

Appendix D: Technical Reference
Principles of Operation
SITRANS LR260 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring
of solids and liquids1). Radar level measurement uses the time of flight principle to
determine distance to a material surface. The device transmits a signal and waits for the
return echo. The transit time is directly proportional to the distance from the material.
Pulse radar uses polarized electromagnetic waves. Microwave pulses are emitted from
the antenna at a fixed repetition rate, and reflect off the interface between two materials
with different dielectric constants (the atmosphere and the material being monitored).
Electromagnetic wave propagation is virtually unaffected by temperature or pressure
changes, or by changes in the vapor levels inside a vessel. Electromagnetic waves are
slightly attenuated by dust.
SITRANS LR260 consists of an enclosed electronic circuit coupled to an antenna and
process connection. The electronic circuit generates a radar signal (25 GHz) that is
directed to the horn.
The signal is emitted from the horn, and the reflected echoes are digitally converted to an
echo profile. The profile is analyzed to determine the distance from the material surface
to the sensor reference point. This distance is used as a basis for the display of material
level and mA output.
Echo Processing
Process Intelligence
The signal processing technology embedded in Siemens radar level devices is known as
Process Intelligence.
Process intelligence provides high measurement reliability regardless of the dynamically
changing conditions within the vessel being monitored. The embedded Process
Intelligence dynamically adjusts to the constantly changing material surfaces within
these vessels.
Process Intelligence is able to differentiate between the true microwave reflections from
the surface of the material and unwanted reflections being returned from obstructions
such as seam welds or supports within a vessel. The result is repeatable, fast and
reliable measurement. This technology was developed as result of field data gained over
some twenty years from more than 1,000,000 installations in many industries around the
world.
1) The microwave output level is significantly less than that emitted from cellular phones.
A5E32337683 SITRANS LR260 (HART) – OPERATING INSTRUCTIONS Page 97
mmmmm
D: Technical Reference
Higher order mathematical techniques and algorithms are used to provide intelligent
processing of microwave reflection profiles. This “knowledge based” technique
produces superior performance and reliability.
Time Varying Threshold (TVT) Curves
A Time Varying Threshold (TVT) curve hovers above the echo profile to screen out
unwanted reflections (false echoes).
In most cases the material echo is the only one which rises above the default TVT curve.
In a vessel with obstructions a large false echo may rise above the default TVT. The Auto
False Echo Suppression feature (see below) can be used to screen it out.
The device characterizes all echoes that rise above the TVT as potential good echoes.
Each peak is assigned a rating based on its strength, area, height above the TVT, amongst
other characteristics.
The true echo is selected based on the setting for the Echo selection algorithm (
2.2.4.1.1.
Algorithm
.).
Echo Lock
If the echo selected by Algorithm is within the Echo Lock window, the window is centered
about the echo, which is used to derive the measurement.
•Lock Off:
SITRANS LR260 responds immediately to a new selected echo (within the
restrictions set by the Maximum Fill / Empty Rate), but measurement reliability is
affected.
Echo Position Detection
The echo position algorithm (
2.2.4.1.2. Echo Position
) determines which point on the echo
will be used to calculate the precise time of flight, and calculates the range using the
calibrated propagation velocity (adjusted by a propagation factor, if necessary).

D: Technical Reference
The options are Center, CLEF (Constrained Leading Edge Fit), Hybrid or Rising Edge. CLEF
uses the leading edge of the echo. It can be used to compensate for materials with a low
dK value, which may cause the vessel bottom to be reported as the level instead of the
actual material level, in low level conditions. CLEF range is the level below which the
CLEF algorithm will be used: above this level the Center algorithm is used.
Hybrid uses a combination of Center and CLEF, depending on the setting for CLEF range.
Auto False Echo Suppression
If an obstruction is causing a large echo before the material level echo, that echo will rise
above the default TVT curve and may be selected as the true echo. Auto False-Echo
Suppression modifies the TVT curve so that the false echo will not rise above the TVT
curve.
When you use Auto False Echo Suppression, the device first learns the echo profile at
that moment1). A learned TVT curve follows the echo profile and rises above the false
echo. You set Auto Suppression Range so that the learned profile replaces the default
TVT curve up to a point past the obstruction. From that point on, the default TVT curve is
used. The material level echo rises above this, and is selected as the true echo.
Measurement Range
Near Range
2.2.1.12. Near Range
programs SITRANS LR260 to ignore the zone in front of the antenna.
The default blanking distance is 50 mm (1.97") from end of horn antenna.
Near Range allows you to increase the blanking value from its factory default. But
2.2.5.2.
Auto False Echo Suppression
is generally recommended in preference to extending the
blanking distance from factory values.
1) Use Auto False Echo Suppression when the material level is substantially lower than pro-
cess full level (ideally when the tank is empty or almost empty).

D: Technical Reference
Far Range
In applications where the base of the vessel is conical or parabolic, a reliable echo may
be available below the vessel empty distance, due to an indirect reflection path.
Increasing the range extension to 30% or 40% can provide stable empty vessel
readings.1)
Measurement Response
The measurement response (response rate) limits the maximum rate at which the display
and output respond to changes in the measurement. Once the real process fill/empty rate
(m/s) is established, a response rate can be selected that is slightly higher than the
application rate. The response rate automatically adjusts the filters that affect the output
response rate.
There are three preset options: slow, medium, and fast.
mA Output
The mA output is proportional to the level, in the range 4 to 20 mA. Generally, the output is
set so that the output for 0% is 4 mA, and the output for 100% is 20 mA. 0 and 100% are
percentages of the full-scale reading (m, cm, mm, ft, in).
When SITRANS LR260 is put into PROGRAM mode it stops responding to the process. It
stores the most recent measurement, and holds the associated readings and mA signal
output. The instrument reverts to the parameter last addressed during the previous
program session.
1) On 30 m vessel, range extension cannot exceed 31.5 m.

When the instrument is returned to Measurement mode, the transceiver resumes
operation. The reading and mA output default to the last measurement taken. The reading
and associated outputs migrate to the current process level at a rate controlled by the
response rate (2.2.7.1).
If SITRANS LR260 is left in PROGRAM
mode for 10 minutes without input, it automatically
reverts to Measurement mode.
Damping
A damping filter smooths out the response to a sudden change in level. This is an
exponential filter and the engineering unit is always in seconds. The setting can be
modified in
2.2.4.3.2. Damping Filter
.
Damping example
Loss of Echo (LOE)
A loss of echo (LOE) occurs when the calculated measurement is judged to be unreliable
because the echo confidence value has dropped below the echo confidence threshold.
If the LOE condition persists beyond the time limit set in
2.4.1. Fail-safe Timer
the LCD
displays the Maintenance Required icon, and the text region displays the fault code S: 0
and the text LOE.
If two faults are present at the same time, the fault code, error text, and error icon for
each fault are displayed alternately. For example, Loss of Echo and Fail-safe High.
S: 0 LOE S: 52 FAIL-SAFE
Fail-safe Mode
The purpose of the Fail-safe setting is to put the process into a safe mode of operation in
the event of a fault or failure. The value to be reported in the event of a fault is selected so
that a loss of power or loss of signal triggers the same response as an unsafe level.

Glossary
Glossary
accuracy: degree of conformity of a measure to a standard or a true value.
algorithm: a prescribed set of well-defined rules or processes for the solution of a problem in a
finite number of steps.
ambient temperature: the temperature of the surrounding air that comes in contact with the
enclosure of the device.
antenna: an aerial which sends out and receives a signal in a specific direction. There are four
basic types of antenna in radar level measurement, horn, parabolic, rod, and waveguide.
attenuation: a term used to denote a decrease in signal magnitude in transmission from one
point to another. Attenuation may be expressed as a scalar ratio of the input magnitude to
the output magnitude or in decibels.
Auto False-Echo Suppression: a technique used to adjust the level of a TVT curve to avoid the
reading of false echoes. (See TVT.)
Auto False-Echo Suppression Distance: defines the endpoint of the TVT distance. (See TVT.)
This is used in conjunction with auto false echo suppression.
beam width: the angle diametrically subtended by the one-half power limits (-3 dB) of the
microwave beam.
beam spreading: the divergence of a beam as it travels through a medium.
blanking: a blind zone extending away from the reference point plus any additional shield
length.The instrument is programmed to ignore this zone.
capacitance: the property of a system of conductors and dielectrics that permits the storage of
electricity when potential differences exist between the conductors. Its value is
expressed as the ratio of a quantity of electricity to a potential difference, and the unit is a
Farad.
confidence: see Echo Confidence: describes the quality of an echo. Higher values represent
higher quality. Confidence threshold defines the minimum value.
damping: term applied to the performance of an instrument to denote the manner in which the
measurement settles to its steady indication after a change in the value of the level.
dB (decibel): a unit used to measure the amplitude of signals.

Glossary
derating: to decrease a rating suitable for normal conditions according to guidelines specified
for different conditions.
dielectric: a nonconductor of direct electric current.1)
dielectric constant (dK): the ability of a dielectric to store electrical potential energy under the
influence of an electric field. Also known as Relative Permittivity. An increase in the
dielectric constant is directly proportional to an increase in signal amplitude. The value is
usually given relative to a vacuum /dry air: the dielectric constant of air is 11.
echo: a signal that has been reflected with sufficient magnitude and delay to be perceived in
some manner as a signal distinct from that directly transmitted. Echoes are frequently
measured in decibels relative to the directly transmitted signal.
Echo confidence: describes the quality of an echo. Higher values represent higher quality.
Echo threshold defines the minimum value required for an echo to be accepted as valid
and evaluated.
Echo Lock Window: a window centered on an echo in order to locate and display the echo’s
position and true reading. Echoes outside the window are not immediately processed.
Echo Marker: a marker that points to the processed echo.
Echo Processing: the process by which the radar unit determines echoes.
Echo Strength: describes the strength of the selected echo in dB referred to 1 V rms.
Echo Profile: a graphical display of a processed echo.
false echo: any echo which is not the echo from the desired target. Generally, false echoes are
created by vessel obstructions.
frequency: the number of periods occurring per unit time. Frequency may be stated in cycles
per second.
Hertz (Hz): unit of frequency, one cycle per second. 1 Gigahertz (GHz) is equal to 109 Hz.
HART: Highway Addressable Remote Transducer. An open communication protocol used to
address field instruments.
horn antenna: a conical, horn-shaped antenna which focuses microwave signals. The larger
the horn diameter, the more focused the radar beam.
inductance: the property of an electric circuit by virtue of which a varying current induces an
electromotive force in that circuit or in a neighboring circuit. The unit is a Henry.
microwaves: the term for the electromagnetic frequencies occupying the portion of the radio
frequency spectrum from 1 GHz to 300 GHz.
1) Many conductive liquids/electrolytes exhibit dielectric properties; the relative dielec-
tric constant of water is 80.

Glossary
multiple echoes: secondary echoes that appear as double, triple, or quadruple echoes in the
distance from the target echo.
Near Blanking: see Blanking
nozzle: a length of pipe mounted onto a vessel that supports the flange.
parameters: in programming, variables that are given constant values for specific purposes or
processes.
polarization: the property of a radiated electromagnetic wave describing the time-varying
direction and amplitude of the electric field vector.
polarization error: the error arising from the transmission or reception of an electromagnetic
wave having a polarization other than that intended for the system.
propagation factor (pf): where the maximum velocity is 1.0, pf is a value that represents a
reduction in propagation velocity as a result of the wave travelling through a pipe or
medium.
pulse radar: a radar type that directly measures distance using short microwave pulses.
Distance is determined by the return transit time.
radar: radar is an acronym for RAdio Detection And Ranging. A device that radiates
electromagnetic waves and utilizes the reflection of such waves from distant objects to
determine their existence or position.
range: distance between a transmitter and a target.
range extension: the distance below the zero percent or empty point in a vessel.
relative humidity: the ratio of the actual amount of moisture in the atmosphere to the maximum
amount of moisture the atmosphere could hold (which varies depending on the air
temperature).
relative permittivity: see dielectric constant.
repeatability: the closeness of agreement among repeated measurements of the same
variable under the same conditions.
shot: one transmit pulse or measurement.
speed of light: the speed of electromagnetic waves (including microwave and light) in free
space. Light speed is a constant 299, 792, 458 meters per second.
stillpipe: a pipe that is mounted inside a vessel parallel to the vessel wall, and is open to the
vessel at the bottom.

Glossary
stilling-well: see stillpipe.
two wire radar: a low-energy radar. Can be loop powered, analog, intrinsically safe 4 to 20 mA,
or a digital (BUS) transmitter.
TVT (time varying threshold): a time-varying curve that determines the threshold level above
which echoes are determined to be valid.
waveguide antenna: a hollow, metallic tube that transmits a microwave signal to the product
target.
