Elniva membrane monitors are used for remote monitoring of the filling level in silos and containers.
They are also very suitable as overflow or overfill protection in
conveyors, cleaners, wipers, scales, etc.
The guards act as diaphragm-actuated switches. A microswitch is controlled by a
rubber membrane, which is sandwiched between a fixed ring and a backing plate (pressure plate).
The membrane is pressed by the material in the container, against the disc and the lever of the microbrewer.
