Paddle Level Switches

A rotary paddle level switch is designed to detect the presence or absence of bulk solids and powders within bins, silos, or hoppers. HK Calibrations provides these robust sensors to Australian industries like agriculture and mining to prevent overfilling and ensure efficient inventory management.

The unit features a low-speed motor that rotates a paddle; when material reaches the paddle, the rotation is impeded, triggering a microswitch to signal a high or low level. HK Calibrations stocks these reliable mechanical sensors because they offer a simple yet highly effective solution for challenging dry-bulk environments.

Yes, most models feature adjustable spring tension to accommodate different material densities, from light powders to heavy grains or ores. HK Calibrations ensures these switches are built with durable stainless steel paddles to withstand the mechanical stress of dense Australian industrial materials.

These switches can be mounted either horizontally or vertically on the side or top of a vessel depending on the specific level detection required. HK Calibrations recommends checking the insertion length and clearance to ensure the paddle can rotate freely without interference from internal silo structures.

Many of our rotary switches are designed with dust-ignition-proof enclosures, making them ideal for use in grain handling and chemical processing plants. HK Calibrations provides these high-quality components to help Australian businesses maintain site safety and comply with rigorous industrial standards.

To ensure continued reliability, HK Calibrations suggests a professional inspection every 12 months to check for seal integrity and motor functionality. Regular maintenance from HK Calibrations helps prevent unexpected downtime and ensures your automated level control systems remain fully operational and NMI-traceable.
