Rotary Paddle Level Switch
Rotary paddle level switch is a level switch device specially used for powder substances and lump-like objects. Rotary paddle level switch is widely used in mining, chemical, beverage processing, cement, plastic, chemical fiber industries, etc. Wepower Electronic has many years of experience in production and processing, contact us now to get more information.
Working Principle Of Rotary Paddle Level Switch:
Rotating the stainless steel blade of the Rotary Paddle Level Switch is accomplished by means of an international standard micromotor. The rotary paddle sensor’s blade is stopped from rotating when material rises to the blade’s position. A resistance signal is then sent to the junction box device, which then outputs a switch signal to the outside world without ever cutting off the power source or stopping the blade’s rotation.
The Rotary Paddle Level Switch is a high-performance, fail-safe, anti-dust solid level switch for powder and grain of various dry materials. Owing to its excellent performance, rotating paddle level switches are often used when handling bulk solids.
How To Maintain The Rotary Paddle Level Switch?
- Since the rotary paddle level switch is a plug and play device, users can check the device after disassembly regularly.
- The user needs to check whether the rotary paddle level switch’s rotating shaft and blades are bent, deformed or damaged.
- Check whether the connection between the rotating shaft and the blade is normal.
- Regularly clean the rotary paddle level switch and remove the debris attached to it.
