Siemens SITRANS Probe LU Ultrasonic Level Transmitter 7ML5221-1BC11
Siemens SITRANS Probe LU 7ML5221-1BC11 ultrasonic level transmitter, 6m range.
The Siemens 7ML5221-1BC11 is a SITRANS Probe LU ultrasonic level transmitter. It provides continuous, non-contact level and volume monitoring for liquids and slurries up to 12m (40 ft) range. This specific model features a 6-meter (20 ft) range with a PVDF copolymer transducer and a G 2" process connection. It offers a 4-20mA HART output and is approved for Ordinary Locations/General Purpose applications (FM, CCSAUS, CE, UKCA, RCM, KC).
This level transmitter is suitable for a wide range of industries, including water and wastewater treatment, chemical processing, food and beverage, and bulk solids handling. Its non-contact measurement principle makes it ideal for corrosive or difficult-to-measure media. The optional PROFIBUS PA communication offers advanced integration capabilities, though this specific model is obsolete and replaced by the SITRANS Probe LU240.
