The 4 Vane Rotating Paddle Level Switch is a reliable and efficient device designed for continuous level detection of bulk solids and powders. Featuring four paddles mounted on a rotating shaft, this switch operates by detecting the resistance encountered when the paddles are obstructed by the material. When the material level rises and blocks one or more paddles, it hinders their rotation, triggering a switch to indicate high or low levels.
Ideal for a variety of applications across multiple industries, including food processing, agriculture, and chemicals, the 4 Vane Rotating Paddle Level Switch provides accurate and dependable level measurement in silos, hoppers, and storage bins. Its robust design ensures long-lasting performance in harsh environments, while its straightforward installation and low maintenance requirements make it a practical choice for continuous level monitoring of bulk materials.
Food Processing: The Rotating Paddle Level Switch is used for monitoring levels of bulk ingredients such as grains, flour, and sugar in silos and hoppers, ensuring efficient storage and processing.
Agriculture: Ideal for detecting levels of animal feed, fertilizers, and seeds in storage bins and silos, preventing overflow and shortages.
Cement and Construction: Employed to monitor levels of cement, sand, and other aggregates in storage facilities and silos, ensuring smooth material flow in construction processes.
Plastic and Rubber Industries: Effectively detects granules and powders in mixing and storage applications, enhancing production efficiency.
Mining and Minerals: The Rotating Paddle Level Switch is used for detecting levels of bulk materials such as ores and aggregates in processing areas, ensuring continuous operation.
Wastewater Treatment: Applied to monitor sludge and solid levels in settling tanks, optimizing wastewater treatment processes.
Pharmaceutical Manufacturing: Utilized for accurate level measurement of powdered raw materials in production processes, maintaining product quality and consistency.

The Rotating Paddle Level Switch operates on the principle of mechanical obstruction, making it highly reliable for bulk solid and powder level detection. It consists of a rotating shaft with four paddles that spin at a constant speed when no material is present.
As the material level rises and comes into contact with the paddles, resistance is created, slowing or stopping their rotation. The internal sensing mechanism detects this change and activates the switch after a predetermined duration, signaling either high or low-level conditions based on the application requirements.
This Rotating Paddle Level Switch is designed for accurate and maintenance-free operation in storage containers such as silos, hoppers, and bins. Its robust construction ensures consistent performance and durability, making it ideal for use in food processing, agriculture, cement, plastics, mining, and other industrial applications.
