Principle of Operation

Every substance has a unique dielectric constant (dK). The sensor uses the difference in dK between material and air or vacuum to determine material presence.
Different types of oscillation and detection circuits, as well as electrodes, are available to suit a wide range of materials and process conditions.

Series resonant circuit is used. The circuit has a detection electrode as a part of the oscillation circuit. Change in the electrode capacitance (△C) renders the circuit to oscillate. The circuit starts oscillation and gives output signals when the material reaches the electrode.
