Description

The Siemens SITRANS Probe LU240 is a compact ultrasonic level transmitter designed for continuous, non-contact measurement in tanks, vessels and industrial process applications. This model provides a 0.2–6 m measuring range with a chemically resistant PVDF Copolymer transducer, 2" NPT process connection and 4–20 mA HART communication. Siemens Process Intelligence and Auto False Echo Suppression help maintain reliable readings even where fixed objects may cause unwanted echoes. The clear local display and four-button HMI make commissioning simple, while its IP66/IP68 enclosure and E33 intrinsically safe approval make it suitable for demanding industrial and hazardous-area installations.

Applications

  • Water and wastewater tanks
  • Chemical storage vessels
  • Liquid storage and process tanks
  • Slurry level monitoring
  • Filter beds and small bulk-material hoppers
