SITRANS Probe LR
SITRANS Probe LR is a 2-wire loop-powered, continuous level measuring instrument that
utilizes advanced pulse radar technology at 5.8 GHz (6.3 GHz in North America). The instrument
consists of an electronic component coupled to the antenna and process connection.
Communication is via HART1, and signals are processed using Sonic Intelligence®.
Specifications

• Pressure (vessel): maximum 3 bar, gauge (43.5 psi, gauge)
Installation
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 hand 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.
WARNINGS:
• This product can only function properly and safely if it is correctly transported,
stored, installed, set up, operated, and maintained.
• Never attempt to loosen, remove, or disassemble process connection or instrument
housing while vessel contents are under pressure.
• This product is designated as a Pressure Accessory per Directive 97 / 23 / EC, and is
not intended for use as a safety device.
• 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.
• The user is responsible for the selection of bolting and gasket materials which will
fall within the limits of the flange and its intended use, and which are suitable for
the service conditions.
• Improper installation may result in loss of process pressure.

• Locate the antenna away from the side wall, to
avoid interference from indirect echoes.
• Avoid interference from objects such as ladders
or pipes, which can cause false echoes.
• Avoid interference from the fill path.

Mounting instructions
• Before inserting SITRANS Probe LR into its mounting connection, check to ensure the
threads are matching to avoid damaging them.
• Simply 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).
• To rotate the enclosure, use a 2 mm Allen key to loosen the three set-screws that secure
the locking collar. Once the enclosure is positioned as desired, tighten the set-screws.

Connecting SITRANS Probe LR1
1. If you want to rotate the instrument on the process connection, use the 2 mm Allen
key provided 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 (2.75") from the end of the cable, and
thread the wires through the strain relief2.
Notes:
• For detailed wiring instructions, please refer to the full Instruction Manual.
• Use shielded, twisted pair cable (wire gauge AWG14 to AWG22).
• Separate cables and conduits1may 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.
1. If cable is routed through conduit, use only approved suitable-size hubs for waterproof application.
Note: Do not rotate the enclosure after programming and vessel calibration,
otherwise an error may occur, caused by a polarity shift of the transmit pulse.
2. If cable is routed through conduit, use only approved suitable-size hubs for waterproof applications.

RUN Mode and PROGRAM Mode
SITRANS Probe LR has two modes of operation: RUN and PROGRAM.
After you complete the installation procedures and power up SITRANS Probe LR, it starts in
RUN mode and detects the material level. It returns the distance (in meters) to the material
level referenced from Empty (process empty level). This is the default start-up display mode.
RUN Mode Display
Use the hand programmer to control the display.
If the echo confidence drops below the echo confidence threshold, the failsafe timer starts
running. When the timer expires, the letters LOE (Loss of Echo) alternate with the reading
every two seconds, and the Reliable Echo indicator is replaced by the Unreliable indicator.
When a valid reading is received, the level reading display returns to normal operation.
1 – Primary Reading (displays level, distance, or volume, in either units or percent)
2 – Secondary Reading (displays Parameter number for Auxiliary Reading)
3 – Echo status indicator: Reliable Echo or Unreliable Echo
4 – Units or Percent
5 – Active bar graph represents material level
6 – Auxiliary Reading (depending on the parameter selected, it displays milliAmp value,
distance, or echo confidence, with units where applicable)
