SITRANS LR250 Overview

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 m (66 ft). It is ideal for small vessels and low dielectric media.
The instrument consists of an electronic component coupled to a horn antenna and either
a threaded or flange type process connection.
SITRANS LR250 supports Foundation Fieldbus (FF) communication protocol. Signals are
processed using Process Intelligence which has been field-proven in over 1,000,000
applications worldwide (ultrasonic and radar). This device can be configured as an FF
(H1) Link Master.
Programming
SITRANS LR250 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, via the 375 Field Communicator, or from a remote location via FF
host system, or AMS Device Manager.
Applications
• liquids and slurries
• bulk storage vessels
• simple process vessels
