Working Principle

The rotary paddle level switch has an instrument motor installed in the junction box, which uses a clutch device to connect the transmission shaft with blades at the other end. When there is no contact with the material, the blade and the motor rotate coaxially along the transmission shaft. When the blade contacts the material, the shaft is blocked, causing the motor to stop rotating and an alarm signal is issued.
