What is capacitive level switch?
Basically capacitive level switch works on capacitance. Like a capacitor, a switch has an insulated electrode that acts as the first plate, and the tank wall (reference electrode) acts as the second plate. The capacity between the two varies depending on the height of the media level. As the level changes, the capacitance changes and so does the electrical output.
