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.
