TPT-N Level Switch

The TPT-N is a level switch integrated with a high quality capacitive switch in one of its sensing probe. It detect sthe change in capacitance that occurs when an electrode surrounded by air is immersed into a liquid medium.This change in capacitance at the electrode of the sensor excites an oscillator. This signal is processed by a inner circuit , So as to control the opening or closing of therelay on the circuit board.At the same time, the level switch integrated a PT100 sensing device.
