Product Description
The P104 high-frequency level sensor is designed for industrial use for limit sensing of the level of liguid 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 or non-conductive with any permittivity. It can be
installed in metal or plastic tanks, pipes, filling tanks, sumps, etc.
It is mainly designed for mounting into the wall of a tank or pipe, in which the actual detection 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).
Can differentiate a specific media from others - the "Medium window" function. E.g. it can differentiate oil from water and air, detect only beer foam and ignore beer and air,etc.
The sensor is made from a stainless-steel housing at one end terminated by a sensing electrode, and terminated at the other and by an ending with a status indicator, control elements and electrical connection.
