Level sensor in hygienic design
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 < 0.5 mm. The level is detected continuously,
regardless of any physico-chemical changes of state in the
media, such as foaming or boiling effects.
This 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).
