Sitron ́s HFS high frequency limit level sensor is designed to effortlessy detect the level of fluids or paste-like media while ignoring the influence of deposits of viscous media (ketchup, yogurt, pastes, syrups, jams and jellies, creams, soap) as well as products such as detergents, alkalis, or various chemicals. The sensor works in the high frequency band, enabling reliable detection of the level of media without interference from coating or build-up on the electrode.
The HFS sensor is an excellent replacement technology for vibrating tuning forks, capacitance, ultrasonic, conductive or optic level sensors in either simple or more demanding applications. The media may be electrically conductive or non-conductive. It can be installed in either metal or plastic tanks, pipes, filling tanks, sumps, etc. and does not rely on a metalic referrence.
The sensor is made from an all stainless steel (AISI 316L) housing with a sensing electrode made from highly resistant PEEK. The top of the sensor features dual LED status indicators with magnetic point (+/-) sensitivity and calibration controls along with an M12 electrical connection. It is designed to be mounted into the wall of a tank or pipe, at the point where level detection is required and can operate at process temperatures up to 105°C.
