RP-21 Adjustable Type Rotary Paddle Level Switch

The working principle of RP-21 Adjustable Type Rotary Paddle Level Switch is a low-speed gear motor with a sliding clutch drives a rotating measuring blade. When the measured material impedes the rotation of the blade, the motor will self-rotate, causing the internal micro switch to actuate and output a detection signal. At the same time, the power to the motor will be cut off, stopping the power supply (detection state). Once there is no measured material, the obstruction of the blade will be relieved. The blade will be reset by the internal spring tension, and the detection signal will be switched on again while the motor is powered on, and the blade will start to rotate again.

Application

Jvler RP-10 Rotary Paddle Level Switch is usually used for the monitoring of full, intermediate, and empty levels of solid material bins. It is suitable for various solid materials, such as powders, granules, gels, or blocks. It can automatically monitor and control the material level. Different models of rotary resistance level switches can meet the requirements of different working conditions and have a wide range of applications in the material conveying and control processes of various industries, such as metallurgy, grain, flour, building materials, cement, power, coal, chemical industry, casting, rubber, environmental protection and dust removal. It is also used in the monitoring of chemical plastics, pharmaceuticals, feed, cement and chemical fertilizers, and the food powder manufacturing and processing industry.
