Hycontrol's RP Series of paddle switches continues to be a popular, low-price choice. The operating principle for a rotary paddle switch is straightforward. A unit consists of a motor assembly and a shaft with a paddle attached to the end. Typically, a paddle mounts through the wall at the bin's top, middle or low level. The positioning depends on the requirements of the particular application. Rotary paddle technology has been used 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. In addition, the Hycontrol range is available with various extension lengths and paddle shape options.
A synchronous motor rotates the paddle at one revolution per minute during regular operation, with no material present. When an infill of material surrounds and impedes the paddle blade, the engine 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 adjustment allows the user to set the probe appropriately for light powders or denser materials. The RP Series also features a triple shaft seal to prevent dust ingress 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.
