Capacitive level switch uses the induction rod to detect the capacitance between the sensing rod and the barrel wall. When the sensing rod is covered by the material, the capacitance gradually increases to reach the matching value of the switches internal line setting. When this line generates a high frequency resonance, this is then detected and turned into a switch.
