Rotary Paddle Level Switch
Rotary Paddle Level Switch
Product Code: SD-R2-10-S
The purpose of the rotary paddle level switch is to detect the presence of solid/powdery material in most kinds of tanks, bins and containers. The unit is usually located through a bin wall at the top, middle or low level of a tank. During normal operation (no material present) a synchronous motor rotates the paddle at one RPM speed. When this paddle rotation is stopped by material movement, surrounding the paddle, motor will stall and cause the Micro-switch to change state (indicating an alarm or control).
Rotary Paddle level switch operating principle is simple. A unit is usually located through a 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 material, surrounding the paddle, motor will stall and cause the Micro switch to change state. (Indicating an alarm or control).
