Principle of Operation
A measuring vane is driven by a synchronous motor. The bearing of the motor inside the housing allows it to swing. The motor is fixed to a switching lug.
If the vane is uncovered, a spring pulls the motor and switching lug to the left position (figure 1).
When material covers the vane and thus stops the rotation, the motor and switching lug swings to the right position (figure 2). The signal output indicates "covered" and the motor is stopped. When the vane becomes uncovered due to falling material, the spring pulls the motor and switching lug back to the left position. The motor is started and the signal output indicates "uncovered".
