2 Rotating Vane evel Monit Model NIR-9 Description The NIR-9 level monit is suitable f wide applications f bulks and solids in silos and hoppers. Regardless of humidity and conductivity of the product, the maximum minimum level is controlled reliably. Available are different vanes and process connections accding to each product and tank size. Operation A synchronous mot drives a rotating vane that is extended into the tank by means of a shaft. As soon as the bulk reaches the rotating vane, its rotation is blocked. The resting fce moves the pivoted mot away from its iginal position. Hereby, a micro switch is actuated, wich gives out an alarm signal. A second microswitch turns off the mot. If the filling level decreases, the rotating vane is released again and the fce of a spring pulls the mot back to its iginal position. The mot gets turned on again and the wking contact is switched back. The switching sensitivity can be adjusted in three steps by changing the spring position.
