KP Specialty Level Instrument

The operation of the ABB Rotary Paddle Switch centers around a low torque, slow speed (1 RPM) synchronous motor. The absence of dry material allows the motor to turn the paddle uninterrupted. When the unit senses the presence of dry material via the restricted rotation of the paddle, the reversing torque actuates the internal SPDT switches and alarms the unit. The hysteresis motor continues to run in a restricted or completely stalled state without damage or overheating. The subsequent alarm can activate two controls, i.e., visual annunciators, start and stop of machinery such as conveyor belts, feeders, etc. The ABB Rotary Bin Level Indicator can be mounted on the top of the bin or on the side of the bin to indicate high, intermediate or low level. Flexible shaft couplings, extended shafts and shaft guards are available to allow for protected operation of the rotating paddle device in almost any position and orientation.
