Low price ESMUS12-WS03 Non-contact capacitive water level switch

The electrodes of the capacitive liquid level switch and the container wall (or another electrode) form a capacitor. When the liquid level changes, the capacitance changes because the dielectric constant of the liquid differs from that of air. The electronic circuit inside the switch continuously monitors the capacitance. When the capacitance reaches a set threshold, the switch changes state and outputs a switch signal, thereby enabling liquid level detection.

1. without environmental impact, high stability;
2. high sensitivity, can be any non-metallic material through the container, such as glass, ceramics, plastics, rubber, etc., the

real non-contact detection;

3. liquid, powder can be detected;
4. unipolar induction, without affecting the surrounding equipment, suitable for complex environments;
5. Wide power supply range, low power consumption;
6. installation is very convenient, is immediately available;
7. sensitivity neat, easy to use batch;
8. collector outputs for connecting various circuit
9. Optional transmitter device to achieve alarm and control functions.
