SITRANS LR250
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 meters (66 feet). It is ideal for small vessels and low dielectric media.
The instrument consists of an electronic circuit coupled to an antenna and either a
threaded or flange type process connection.
SITRANS LR250 supports HART1) communication protocol. Signals are processed using
Process Intelligence which has been field-proven in over 1,000,000 applications
worldwide (ultrasonic and radar).
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, or from a remote location using one of the following options:
• SIMATIC PDM
• AMS Device Manager
• FDT/DTM platform (such as PACTware™ or FieldCare)
• HART Handheld 375/475
Applications
• liquids and slurries
• bulk storage vessels
• simple process vessels
WARNING: SITRANS LR250 is to be used only in the manner outlined in
this manual, otherwise protection provided by the device may be
impaired.
