Conductivity :

 

The PSI ConductiSwitchTM is an very economical liquid level switch that is ideal for a variety of conductive liquid level detection applications, including: run-dry protection, tank overfill, and pump control.

The ConductiSwitchTM is a simple, safe, and low maintenance liquid level switch utilizing the conductivity sensing technology.

A small AC signal is applied between the conductive electrode, mounted with its tip located at the point to be detected, and earth ground (typically the liquid container).

When the liquid touches the electrode an extremely small AC current begins to flow (no electrolysis). The current is detected by the electronic module and converted into a switching signal.
