For sanitary applications, this manufacturer has developed a magnetostrictive level sensor in hygienic design. The model FLM-H sensor, is certified in accordance with 3A Sanitary Standards, and measures level in tanks and vessels with an accuracy of less than 0.5 mm. The level is detected continuously, regardless of any physicochemical changes of state in the media, such as foaming or boiling effects. Based on the float principle, the device even operates reliably with clean- and steam-in-place (CIP/SIP) processes. The 4–20-mA output of the sensor (also available with HART protocol) transmits the signal over long distances. The sensor is also suitable for SIL 2 (IEC 61508) installations. — WIKA Alexander Wiegand SE & Co. KG, Klingenberg, Germany
