Rotating vane level monitor NIR-9 - Kobold

The NIR-9 level monitor is suitable for wide applications for bulks and solids in silos and hoppers. Regardless of humidity and conductivity of the product, the maximum or minimum level is controlled reliably. 
A motor drives a rotating vane that is extended into the tank by means of a shaft. As soon as the bulk reaches the rotating vane, it’s rotation is blocked. Hereby, a microswitch is actuated, wich gives out an alarm signal and a second microswitch turns off the motor. If the filling level decreases, the rotating vane is released again and the force of a spring pulls the motor back to its original position.
