SITRANS Probe LU240 – compact ultrasonic level transmitter

Why SITRANS Probe LU240?

SITRANS Probe LU240 delivers reliable, low-maintenance ultrasonic level measurement for demanding environments. Advanced echo processing, rugged IP68 construction, and flexible power and connectivity options enable accurate data, easy installation and lower lifetime costs — helping you maximize uptime and asset efficiency.

Achieve reliable, intelligent measurements

Leverage state-of-the-art Process Intelligence echo processing to separate true level signals from false echoes, delivering accurate, repeatable measurements with fast response — even in challenging applications.

Reduce maintenance in harsh environments

Eliminate buildup with maintenance-free active face technology and rely on an IP68 fully potted, encapsulated PVDF sensor that withstands corrosion, chemicals, and extreme shock.

Simplify powering and connectivity

Support battery and solar installations with low start-up current and 10.5 V operation, while enabling easy commissioning through HART 7, push-button setup, remote configuration, and optional Bluetooth.
