SITRANS LR250 overview
WARNING
SITRANS LR250 is to be used only in the manner outlined in this manual, otherwise
protection provided by the device may be impaired.
SITRANS LR250 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring of
liquids and slurries in storage vessels including high pressure and high temperature, to a range
of 20 meters (66 feet). It is ideal for small vessels and low dielectric media.
The device consists of an electronic circuit coupled to an antenna and either a threaded or
flange type process connection.
This device supports PROFIBUS PA 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). This device supports acyclic communications from
both a PROFIBUS Class I and Class II master.
