Rotary Paddle Level Switch has a simple structure, is widely used, and is easy to maintain. It is an ideal material level control instrument, suitable for controlling material levels in industrial production processes. When the material level reaches the high or low limit, the contact outputs an alarm or control signal. It is easy to install and can be installed in any shape of warehouse, hopper, tank, and other containers.

Measuring principle
The anti rotation material level switch uses a clutch to connect the motor with the transmission shaft. When the motor is not in contact with the material, it maintains normal operation. When the blade contacts the material and causes resistance, the blade stops rotating. The limit switch is activated, and the output contact signal reflects the material level height. At the same time, the motor power is turned off. The motor stops rotating. When the stacking height of the measured material decreases and no longer hinders the blade rotation, the motor restarts, The contact signal returns to its initial state.
