Rotary Paddle Switches

Hycontrol's RP Series of paddle switches continues to be a popular, low-price choice. The operating principle for a rotary paddle switch is very simple. A unit consists of a motor assembly and a shaft with a paddle attached to the end of it. The paddle is mounted through the wall at the top, middle or low level of a bin, depending on the requirements of the application. This technology has been in use for many years, providing point level indication and bin level switching in many industries.

This low-cost technology is excellent for solid products such as cement, sand and plastic pellets. The Hycontrol range is available with various extension lengths and paddle shape options.

During normal operation, with no material present, a synchronous motor rotates the paddle at one revolution per minute. When the paddle rotation is impeded by an infill of material surrounding the paddle blade, the motor will stall and cause a microswitch to change state, indicating an alarm or providing a control function.

The switches have a torque-adjusting mechanism based on a spring setting. This provides adjustment for light powders or denser materials. The RP Series also features a triple shaft seal to prevent ingress of dust into the unit housing.

The rotary paddle switch remains a popular level device for many applications, and Hycontrol is pleased to offer a range of these products.
