Granular Material Sensors

A resistance rotary switch is used to control the level of solid materials including powder, massive, granular, gel, etc.

The motor rotates a blade, and when arrives at the level of the measured medium, the blade gets blocked and stops running, which touches the back of the micro switch output switch signals. When the level of the measured medium drops, it frees the blade, and the blade under the action of the spring continues to rotate.
