Rotating Paddle Switch for Bulk Solids

详情

~Products Description

~It has outstanding features such as good sealing, strong overload capacity, lightweight and easy to installation, large output contacts capacity, etc. In view of the different Sensibility of material can be done by adjustable tension of the spring, contact material part of its full stainless steel material. Resistance rotary switch in the chemical, plastic, cement, medicine, feed, food and other industries widely used.

~Working Principle

~A low revolution geared motor with slip clutch drives a rotating measuring vane which senses the presence of material at the mounted level of the S*0&S3. As material comes into contact with the rotating paddle, rotation stops, which changes the microswitch state. When the paddle is no longer covered by material, rotation resumes and the relay reverts to its normal condition.
Tension of the spring may be adjusted according to the Sensibility of the measured medium.  Spring is adjusted to the strongest when material Sensibility get the max, on the contrary, it is adjusted to the weakest.
~Products Features
~1. American small hopper apparatus technology, three bearing support, more                             reliable operation.
2. The original seal design can prevent the dust into (patent) actual
3. The performance of torsion is stable and reliable..
4. If the rotary paddle bears an extra overload, the motor will be appeared slide to prevent the inside mechanism damaged.    
5. It is rationally designed, the inside mechanisms are easily tore down for checking, maintenance and replacement. It doesn’t necessary to remove the complete set from the tank.
6. The junction box is IP*5 protection grade, good sealing, and can be used outdoors
7. Special vane can be used in low density materials.
8. It can be used in wide range such as the iron and steel, cement, electric power, feed, chemical plastics, chemical fertilizer industry, etc
