Working principle
The electric motor drives the blades to rotate. When the measured medium reaches the blade position, the blades are obstructed and stop rotating, thereby triggering the output switch signal of the micro switch behind. When the measured medium descends and leaves the blades, the blades return to their original position and continue to rotate under the action of the spring. The tension of the spring can be adjusted by the specific gravity of the measured medium. When the material ratio is high, the spring is adjusted to the strongest, and vice versa.
Product Features

Product application
　　Material level resistance rotary switchIt is a level controller used for solid materials (including powder, block, granular, gel, etc.). It has the characteristics of good sealing, strong overload capacity, lightweight and easy to install, and large output contact capacity. For materials with different densities, it can be achieved by adjusting the tension of the spring, and the part in contact with the material is entirely made of stainless steel material. Resistive rotary switches have been widely used in industries such as chemical, plastic, cement, pharmaceutical, feed, and food.
