Electrical Conductivity Level Sensor MT10

Principle of Operation

The sensor has a pair of electrodes, and applies alternating current to them. When the liquid covers the electrodes, it forms a part of an electric circuit, causing current to flow. The sensor measures electric resistance of the liquid, and compares the measured value with a preset value to determine liquid presence. When liquid presence is detected, the sensor sends a signal to an amplifier to open or close relay contacts of relay units.
