Rotary Paddle Switch

KP Rotating Paddle Switch - 13593 KP

The operation of the K-TEK 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 K-TEK 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.

APPLICATIONS TYPICAL INSTALLATIONS

The Model KP’s durable, rugged design is compatible with many bulk solids, pelletized and granular applications. The KP rotary paddle switch can be used for level indication of materials with densities of 10 lbs./ft3 and greater. The KP is ideal for installations where almost any dry bulk material is contained in hoppers, silos, bins and tanks. Typical applications and approximate densities include, but are not limited to:
