The MHF15 is a compact optical level limit switch that is easy to commission. The sensor is based on SICK's energetic photoelectric proximity sensor technology, which has been tested and optimized over a number of decades. This sensor has a simple, robust and reliable construction. The use of high-quality materials, such as stainless steel 1.4404 and polysulfone, combined with the IP 69K-rated housing, provides reliability not only on the process side, but also in situations where there are adverse ambient conditions outside the tank. In addition, fast, hassle-free commissioning does not require medium calibration, reducing commissioning costs and maintenance. The optical technology makes the MHF15 particularly well-suited to use with water-based media.
