Rotation Switch Series

Rotation Switch Series

Principle of Operation

The rotating measuring vane is driven by a brushless synchronous motor. Once the material level reaches the vane, it stops rotating, which is detected by a micro switch to stop the motor and switch the level output. Once the material level begins to fall and the vane is free of material the motor will restart and the vane will rotate again.
