Siemens SITRANS Probe LU Loop-Powered Long Range Ultrasonic Level Transmitter
Loop-powered ultrasonic transmitter for liquid level measurements in open channels, storage vessels and simple process vessels up to 40 feet (12 meters).
This product has been discontinued by the manufacturer. Please see Siemens SITRANS Probe LU240 for a suitable replacement.
Siemens SITRANS Probe LU is a two-wire, loop-powered integrated ultrasonic level transmitter that includes automatic false-echo suppression, Milltronics' patented Sonic Intelligence echo processing, with digital communications and programming options in a single unit. The Probe LU is ideal for level monitoring in the water and wastewater industry and chemical storage vessels, and can reliably monitor level, volume, and flow of liquids in open channels, storage vessels, and process vessels.
The transducer on the Probe LU is available as ETFE or PVDF to suit the chemical conditions of your application. To compensate for temperature changes in applications with varying material and process temperatures, the Probe LU incorporates an internal temperature sensor. It comes with two communications options: HART® with 4-20 mA output or PROFIBUS PA (Profile v3.0, Class B).
