Rotary paddle level switch type: SE3820DCRG1000

The operating principle of the SE series is simple. This level switch SE series is placed through the wall at the highest or lowest level of a (bulk) tanks, silos, containers or reservoir. During normal operation (no material present), a synchronous motor rotates the paddle at 1 RPM. When the paddle is obstructed by material, the motor will stall and cause the microswitch to switch.
