Rotary Paddle Level Switch

The RS rotary paddle level switch adopts a synchronous motor whose drive shaft is connected to a clutch. When no material contacts the paddle, the motor keeps running normally. When the paddle encounters material and suffers resistance, the motor stops immediately and outputs a passive dry contact signal. When the material level drops away from the paddle, the spring drives the paddle to reset and resume rotation. While detecting the change of material level, the internal mechanism outputs contact signals synchronously.
