Sitrans Probe LU240






Sitrans Probe LU240

SITRANS Probe LU240 ultrasonic level transmitter with HART, 4 to 20 mA is ideal for level, volume, and volume flow measurements. It works with liquids, slurries, and bulk materials up to 12 meters (40 feet). The range of SITRANS Probe LU240 is 6 or 12 m (20 or 40 ft).

The SITRANS Probe LU240 offers HART communication.

The transducer on the SITRANS 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 SITRANS Probe LU240 incorporates an internal temperature sensor to compensate for temperature changes.

Key Applications: chemical storage vessels, filter beds, liquid storage vessels
