SIEMENS SITRANS Probe LU240 Process Instrumentation
Level Measurement Continuous Ultrasonic New & Original
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
Application
The 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 6 or 12 m (20 or 40 ft). Using Process Intelligence,
Auto False Echo Suppression for fixed obstruction avoidance, and accuracy of 0.15 % of range or 6 mm (0.25 inch), the Probe LU240 provides unmatched reliability.
The Probe LU240 offers HART communication.
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, the Probe LU240 incorporates an internal temperature sensor to compensate for temperature changes.
Key Applications: chemical storage vessels, filter beds, liquid storage vessels
