The Capacity level sensor RFLS–35 is designed for industrial use for limit sensing of the level of fluid and paste-like media. The
high-frequency level sensor may be a direct replacement of a vibrating level sensor, or of a capacity level sensor in case of more
demanding applications. The media may be electrically conductive and non-conductive with any permittivity. It can be installed in metal
or plastic tanks, pipes, filling tanks, sumps, etc. The sensor is comprised of a stainless steel housing AISI 316L at one end terminated
by a sensing electrode made from PEEK material, and terminated at the other end by a stainless steel ending with status indicator,
control elements and electrical connection. It is designed for mounting into the wall of a tank or pipe, in which the actual ascertain-
ing of the level will take place. The sensor works in the high frequency band, enabling reliable detection of the level of media, and
eliminating deposits or foam on the electrode. The sensor suppresses the influence of deposits of viscous media (ketchup, yoghurt,
pastes, syrups, jams and jellies, creams, soap) as well as electrically conductive adhesive products (detergents, alkalis, chemicals).
