Introduction: The 3 Vane Rotating Paddle Level Switch is a robust and efficient device designed for continuous level measurement of bulk solids and powders. It features three paddles mounted on a rotating shaft. When the material level rises and obstructs the paddles, the resulting resistance is detected by the internal mechanism, triggering a switch to indicate high or low levels.
Applications:
- Food Processing: Monitoring levels of bulk ingredients such as grains, flour, and sugar in silos and hoppers.
- Agriculture: Detecting levels of animal feed, fertilizers, and seeds in storage bins and silos.
- Cement and Construction: Monitoring levels of cement, sand, and other aggregates in storage facilities and silos.
- Plastic and Rubber Industries: Level detection of granules and powders in mixing and storage applications.
- Mining and Minerals: Detecting levels of bulk materials such as ores and aggregates in processing areas.
- Wastewater Treatment: Monitoring sludge and solid levels in settling tanks to ensure efficient treatment processes.
- Pharmaceutical Manufacturing: Accurate level measurement of powdered raw materials in production processes.

Working Principle: The 3 Vane Rotating Paddle Level Switch operates on the principle of mechanical obstruction. A motor drives the rotation of the triple paddles at a fixed speed. In the absence of material, the paddles spin freely. As the material level rises and contacts the paddles, resistance to the rotation increases. This resistance is detected by the internal sensing mechanism, which then triggers a switch to indicate the presence of material at the specified level. This method ensures accurate and reliable level detection for bulk solids and powders.
Features:
- Robust Construction: Designed to withstand harsh industrial environments
