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.

The 4 Vane Rotating Paddle Level Switch operates on the principle of mechanical obstruction. It features four paddles mounted on a rotating shaft that spins at a constant speed. When the material level is below the paddles, they rotate freely without resistance.
As the material level rises and makes contact with one or more of the paddles, it creates resistance against their rotation. This change in rotational speed is detected by the internal sensing mechanism. If the paddles are obstructed for a predetermined duration, the switch is activated to indicate either a high or low material level, depending on the application.
This design ensures reliable and accurate level detection for bulk solids and powders in various containers such as silos, hoppers, and storage bins. The 4 Vane Rotating Paddle Level Switch is particularly effective in industrial environments, providing consistent performance and durability under challenging conditions.
