Description

The CLD1EA1CM24 is a conductive level controller that uses a single electrode to detect the liquid level in a tank. The sensor generates an electrical signal when the electrode comes into contact with the liquid. This signal activates a relay that controls a pump or valve to fill or empty the tank.

The controller includes a potentiometer to adjust the sensor sensitivity and a time control circuit that allows setting an ON/OFF delay to prevent dry running of the pump during emptying and overflow of the tank during filling.

Precautions

Tank Overflow During Filling:

Take precautions to ensure that the tank does not overflow. Factors to consider are the pump performance, the discharge rate of the tank, the position of the single level electrode, and the time delay.

Avoiding Dry Running of the Pump During Emptying:

Ensure that the pump does not run dry by taking similar precautions as mentioned above. Maintaining the time delay at a minimum level reduces risks, although it will increase the switching speed.
