Rotary Paddle Level Switch

Principle

The Paddle Switch operating principle is simple. A unit is usually located through the bin wall at the top, middle or low level of a bin. During normal operation (no material present) a synchronous motor rotates the paddle at 1 RPM. When this paddle rotation is impeded by the material surrounding the paddle, the motor will stall and cause the microswitch to change state and indicate an alarm or control condition.
