Overview

SITRANS Probe LU240 ultrasonic level transmitter, ideal for level, volume, and volume flow measurements.
It works with liquids, slurries, and bulk materials up to 12 m (40 ft).

Benefits

Continuous level measurement up to 12 m (40 ft) range
Easy installation and simple startup
Programming using 4-button HMI or SIMATIC PDM
Communication using HART
ETFE or PVDF transducers for chemical compatibility
Process Intelligence signal processing
Auto False Echo Suppression for fixed obstruction avoidance
Low power and current startup
Optional Bluetooth configuration and monitoring via SITRANS mobile IQ

Application

SITRANS Probe LU240 is ideal for level monitoring in the water and wastewater industry, chemical storage vessels, and small bulk hoppers.
The range of SITRANS Probe LU240 is 3, 6, or 12 m (10, 20, or 40 ft).
Probe LU240 provides unmatched reliability, using Process Intelligence, Auto False Echo Suppression for fixed obstruction avoidance, and accuracy of 0.15 % of range or 6 mm (0.25 inch) (on 6 m and 12 m models only).
SITRANS Probe LU240 offers HART communication on certain models and mA output on all models.
SITRANS mobile IQ is a Bluetooth app that provides an intuitive interface to quickly configure, set up, and monitor
SITRANS Probe LU240 series (available for Android, Apple, and Windows devices). For more information: http://www.siemens.com/mobileIQ.
The transducer on the Probe LU240 is available as ETFE or PVDF to suit the chemical conditions of your application.
As well, for applications with varying material and process temperatures, Probe LU240 incorporates an internal temperature sensor to compensate for temperature changes.
Key Applications: chemical storage vessels, filter beds, liquid storage vessels
