WIKA FLM-H hygienic level sensor

For sanitary applications, WIKA has developed a magnetostrictive level sensor in hygienic design. The model FLM-H sensor, certified in accordance with 3A Sanitary Standards, measures level in tanks and vessels with an accuracy of better than 0.5 mm. The level is detected continuously and regardless of any physicochemical changes of state in the media, such as foaming or boiling effects.

The measuring instrument, based on the float principle, even operates reliably with CIP/SIP processes - cleaning liquids and elevated temperatures do not have any negative influence. The guide tube is directly welded to the process connection. This leads to a crevice-free joint between the connection and the measuring cell, without the need for additional seals.

The 4-20 mA output of the sensor, also available with HART protocol, transmits the signal even over long distances. The level is displayed proportional to volume or height. No calibration is required following installation. The sensor is suitable for SIL 2 (IEC 61508).
