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 component coupled to a horn antenna and either
a threaded or flange type process connection.
SITRANS LR250 supports HART
1)
communication protocol, and the following device
management software options:
• SIMATIC PDM
• AMS Device Manager
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
Applications
• liquids and slurries
• bulk storage vessels
• simple process vessels
