Our Rotating Paddle Level Switch is a robust, cost-effective solution for detecting solid material levels in bins, silos, and hoppers. Ideal for powders, granules, and bulk solids, this switch uses a motor-driven rotating paddle that stops when it encounters material, triggering a signal for level indication.

How It Works The paddle rotates freely when the bin is empty. As material fills and reaches the paddle, resistance increases and the paddle stops, activating a signal. When the material recedes, the paddle resumes rotation and the signal resets. .
