Capacitance Level Switches
Category Selection
Capacitive level switches are contact sensors that detect presence by evaluating the difference in the dielectric values of air (typically) and the measured media. When the media comes into contact with the sensing face, the sensor detects the change in capacitance and provides a discrete output. Capacitive level switches are useful for detecting the level of solids such as plastic pellets, or water-based conductive liquids.
