3.1 SITRANS Probe LR
SITRANS Probe LR is a 2-wire loop-powered, continuous level measuring instrument that
utilizes advanced pulse radar technology operating at a frequency of approximately 6 GHz.
The instrument consists of an electronic component coupled to the antenna and process
connection. It is very easy to install and set up, using either the infrared handheld
programmer locally, or using SIMATIC PDM from a remote location.
Communication is via HART. Signals are processed using Process Intelligence which has
been field-proven in over 500,000 applications worldwide (ultrasonic and radar).
SITRANS Probe LR is available in two versions
●General purpose (non-hazardous)
●Intrinsically Safe (with suitable barrier)
Applications

4.1 Basic safety notes
4.1.1 Incorrect disassembly
WARNING
Incorrect disassembly
The following risks may result from incorrect disassembly:
- Injury through electric shock
- Risk through emerging media when connected to the process
- Risk of explosion in hazardous area
In order to disassemble correctly, observe the following:
•Before starting work, make sure that you have switched off all physical variables such
as pressure, temperature, electricity etc. or that they have a harmless value.
•If the device contains hazardous media, it must be emptied prior to disassembly. Make
sure that no environmentally hazardous media are released.
•Secure the remaining connections so that no damage can result if the process is started
unintentionally.
DANGER
Pressure applications
Danger to personnel, system and environment will result from improper disassembly.
•Never attempt to loosen, remove, or disassemble process connection while vessel
contents are under pressure.
Note
Product designation
This product is designated as a Pressure Accessory per Directive 2014/68/EU and is not
intended for use as a safety device.

Note
Chemical compatibility
Materials of construction are chosen based on their chemical compatibility (or inertness) for
general purposes. For exposure to specific environments, check with chemical compatibility
charts before installing.
Note
Material compatibility
Siemens can provide you with support concerning selection of sensor components wetted by
process media. However, you are responsible for the selection of components. Siemens
accepts no liability for faults or failures resulting from incompatible materials.
4.2 Mounting location
Recommendations
●Ensure ambient temperature is within –40 to 80 °C (–40 to 176 °F).
●Provide easy access for viewing the display and programming via the handheld
programmer.
●Ensure the environment is suitable to the housing rating and materials of construction.
Precautions
●Avoid proximity to high voltage or current wiring, high voltage or current contacts, and to
variable frequency motor speed controllers.
●Avoid interference to the emission cone from obstructions or from the fill path.
●Avoid central locations on vessels.

②
Locking collar over threaded connection; secured by three 2 mm Allen set-screws.
When the locking collar is secured, it prevents the enclosure rotating on the threaded connec-

Avoid central locations on vessels
For vessels with conical or parabolic tops, avoid mounting the device at the center. The
concavity of the top can focus echoes into the center, giving false readings.
4.3 Nozzle location
Beam angle
●Beam angle is the width of the cone where the energy density is half of the peak energy
density.
●The peak energy density is directly in front of and in line with the rod antenna.
●There is a signal transmitted outside the beam angle, therefore false targets may be
detected.

Emission cone
●Keep emission cone free of interference from ladders, pipes, I-beams or filling streams.
●Locate the antenna away from the side wall, to avoid interference from indirect echoes.
●Make allowance for the emission cone spreading: allow a minimum of 300 mm (1 ft) for
every 3 m (10 ft) of vessel height.
4.4 Nozzle design
The end of the shield section or end of the horn should protrude a minimum of 10 mm (0.4”)
to avoid false echoes being reflected from the nozzle.

Location on a manhole cover
●A manhole cover is typically a covered nozzle with a diameter 610 mm (24”) or greater.
●For optimum signal conditions, locate the antenna off-center, typically 100 mm (4") from
the side.
Note
Nozzle design
•
For nozzles 100 mm (4") in length or shorter, use the 100 mm (4") shield.
•
For nozzles 250 mm (10") in length or shorter, use the 250 mm (10") shield.
4.5 Mounting instructions
Note
Rotating the enclosure
Do not rotate the enclosure after programming and vessel calibration, otherwise an error
may occur, caused by a polarity shift of the transmit pulse.
1. Before inserting SITRANS Probe LR into its mounting connection, check to ensure the
threads are matching, to avoid damaging them.
2. Screw SITRANS Probe LR into the process connection, and hand tighten. For pressure
applications, it will be necessary to use PTFE tape (or other appropriate thread sealing
compound) and tighten the process connection beyond hand tight. The maximum torque
is 40 N-m (30 ft.lbs.).
3. If you need to rotate the enclosure, use a 2 mm Allen key to loosen the three set screws
that secure the locking collar.
4. Once the enclosure is in a suitable position, tighten the set screws.

Note
•
Use shielded, twisted pair cable (wire gauge AWG 14 to 22).
•
Separate cables and conduits may be required to conform to standard instrumentation
wiring practices or electrical codes.
•
The non-metallic enclosure does not provide a continuous ground path between conduit
connections: use grounding type bushings and jumpers.
•
For detailed information on Intrinsic Safety setups, see the full Operating instructions.
1. If you want to rotate the enclosure, use a 2 mm Allen key to loosen the 3 Allen set screws
securing the locking collar. Position the unit and retighten the screws.
2. Strip the cable jacket for approximately 70 mm from the end of the cable, and thread the
wires through the strain relief. If cable is routed through conduit, use only approved,
suitably-sized hubs for waterproof applications.
3. Connect the wires to the terminals: the polarity is identified on the terminal block.
4. Tighten the strain relief to form a good seal.
5. Close the lid and tighten screws. Do not overtighten screws. Recommended torque is 1.1
to 1.7 N-m (10 to 15 in-lb) of torque.
