SITRANS Probe LR
■ Overview
■ Configuration
Installation
Min. 300 mm (1 ft) for every
3 m (10 ft) of vessel wall
Note:
• 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.

SITRANS Probe LR is a 2-wire, 6 GHz pulse radar level transmitter for continuous monitoring of liquids and slurries in storage
vessels with nominal pressure and temperature, to a range of
20 m (66 ft).
Mounting unit on vessel
■ Benefits
• Uni-Construction polypropylene rod antenna standard
• Easy installation and simple start up
• Programming using infrared Intrinsically Safe handheld
programmer, SIMATIC PDM or HART handheld communicator
• Communication using HART
• Process Intelligence signal processing
• Auto False-Echo Suppression of false echoes

■ Application
Probe LR is designed for safe and simple programming using
the Intrinsically Safe handheld programmer without having to
open the instrument’s lid. It has a standard Uni-Construction
polypropylene rod antenna that offers excellent chemical resistance and is hermetically sealed. The Uni-Construction antenna
includes an internal, integrated shield that eliminates vessel nozzle interference.
SITRANS Probe LR incorporates Process Intelligence signal processing. The Probe LR also has a high signal-to-noise ratio leading to improved reliability.
