Rotating Paddle Level Switch

The Series RPS201 Rotating paddle level switch is manufactured to detect high / low levels of free-flowing dry solid material, such as fine coarse, powders and granules. It is mounted through the wall of a vessel such that the paddle remains above the surface inside the vessel.

A small electric motor drives a paddle that rotates freely in the absence of material, but is impeded when material is present. When the rotating paddle is obstructed due to the texture of powder material, a micro-switch output activates to signal an alarm.
