How it works; NivoRota Rotary Paddle Switch

The NivoRota rotary paddle switch uses a low power electric motor to drive a paddle that rotates freely in the absence of bulk-solids material. If the material impedes the rotary paddle, the output switch is triggered and the motor is switched to increase the longevity of your level switch. Once the material level drops again, the motor resumes operation and the switch returns to its original state. The NivoRota is available with multiple different paddles, different power supplies and process connections to ensure you have a rotary paddle switch suited to your application!
