The RFLS-28 high-frequency level sensor is intended for industrial use for limit level sensing of liquid and pastes
media. It is designed for vertical mounting in the tank or using a tubular extender (see the technical datasheet for
accessories) or a bracket. It can directly replace vibrating level sensors, or capacitive level sensors in more demanding applications. Media can be electrically conductive as well as non-conductive. The sensor can be installed in metal or plastic tanks, filling tanks, sumps, etc.
The sensor is also suitable for detecting levels of both viscous and electrically conductive media (yogurt, jams, mayonnaise, spreads, liquid soaps, creams, and pastes). After setting the sensitivity to a specific medium, the sensor reliably reacts to the presence or absence of a medium level. The sensor does not react to residues and deposits of viscous media on the measuring electrode.
The sensor can also be used to distinguish a specific medium from others – using the “Medium window” function.
E.g. the sensor can distinguish oil from water and air, can detect only beer foam and ignore beer and air, etc.
