SITRANS LR260
SITRANS LR260 Overview
SITRANS LR260 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring
of solids and liquids in storage vessels including extreme levels of dust and high
temperatures, to a range of 30 m (98.4 ft).
The instrument consists of an electronic component coupled to a horn antenna with an
integral Easy Aimer and flange for quick and easy positioning. A dust cover or air purging
are available as options.
SITRANS LR260 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.
Programming
SITRANS LR260 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 hand-
held programmer, or from a remote location via SIMATIC PDM.
