Rotary paddle level switch utilizes micro motor as drive device, transmission shaft contact with clutch. When it does not contact with material, the motor runs normally; when the blade contacts with material, the motor stops running; testing device outputs a contact signal and cuts the power and it stops rotary in the meantime. The pressure to blade is disappear when the material gradually fall down, and the testing device recovered to the original state by torsion spring. Torsion could be regulated according to different gravity of material. RD series of rotary paddle level switch specially used for detecting material level of warehouse, vessel and tank. The material level switch can prevent warehouse flooding, tank jam and warehouse empty so as to reduce flooding, material waste and standby time. Rotary paddle level switch is also other solid matter rotary paddle level switch can eliminate the normal fault of common rotary paddle level switch. When adding material, it would not go to stop though the motor stops by cutting power. This can reduce fraction, operating temperature and extend the lifetime of motor. The switch contains little moving parts, three sets of drive bearing and sealed, lubricated driving gear assembly. That is why the RD series of rotary paddle level switch gains reliable control force in the market
