Construction :
The RF level switch is working on the COAT GUARD TECHNOLOGIES incorporating DRIVEN SHIELD AND PISTON CAPACITOR circuits, providing a very low impedance coat guard terminal to power a driven shield on the sensing element. This prevents the conductive and non-conductive coating from causing false signal. This makes the system different than the conventional RF Capacitance level switch. The major difference is of COAT GUARD design which is exactly at the same voltage and phase at all the time. This prevents the material build-up causing a false alarm, which otherwise will cause a false alarm in conventional capacitance level measuring system

It consists of an acoustic signal receiver (Microphone Unit / Sound Sensor) and specially constructed indicating & interpreting electronic circuit (Control Unit). Depending on the height of the material bed, the grinding media inside the Ball Mill causes a characteristic noise.
In case of high material bed (max. filling level), there is hollow grinding sound (low volume & low grinding frequency), whereas for low material bed (min. filling level), there is high pitched sound (high volume & high grinding frequency). This characteristic of grinding frequency is used to develop an output signal representing mill filling level, which can be used for regulation of the mill feed and / or for digital
indication of the mill filling level.
