The SER 2 level transducer is a compact device which works using the capacitive method of measurement. The level transducer can continuously measure filling levels in the defined measurement range in electrically conductive and non-conductive media.
The SER 2 level transducer has a transmitter integrated in the connecting housing and provides a level-proportional measurement current of 4-20 mA.
Capacitive filling level measurement methods are based on the principle of an electrical capacitor. If, between two condensate plates, the filling level of a dielectric changes, the current flowing through the plates also changes in proportion to the filling level. A dielectric is, by definition, an insulating substance, which does not include, however, many filling media, such as water. In order to obtain a usable measurement result nonetheless, the measurement rod that is dipped into the medium is completely insulated. After a 0-100% adjustment of the control electronics, the filling level can be read off, for example, at a remote display. The filling level measurement range can be changed during operation.
