Rotation Switch

The rotation switch series is used for level sensing of low-density and potentially explosive powders. Each switch unit uses a rotating vane as a sensor to detect the level of a dust or powdered material. The vane is turned slowly by a brushless synchronous motor. As long as the level of the powder remains below the vane, the vane is free to turn. If the powder rises to the level of the vane, rotation stops. A switch turns off the synchronous motor and produces an output for an external control system. The vane sensing system enables the switch to be used for powdered materials with low densities (greater than 6 lb/cu ft).
