3 Vane Rotating Paddle Level Switch

The 3 Vane Rotating Paddle Level Switch is a robust and efficient device designed for continuous level measurement of bulk solids and powders. Featuring three 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 various applications across multiple industries, including food processing, agriculture, and chemicals, the 3 Vane Rotating Paddle Level Switch provides reliable and accurate level measurement in silos, hoppers, and storage bins. Its durable 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: Used for monitoring levels of bulk ingredients such as grains, flour, and sugar in silos and hoppers.

Agriculture: Ideal for detecting levels of animal feed, fertilizers, and seeds in storage bins and silos.

The 3 Vane Rotating Paddle Level Switch operates on the principle of mechanical obstruction. It features three paddles mounted on a shaft that rotates at a fixed speed. When the material level is below the paddles, they rotate freely without any resistance.

As the material level rises and comes into contact with one or more paddles, it creates resistance against their rotation. This change in rotational speed is detected by the internal sensing mechanism. If the paddles remain obstructed for a specified duration, the switch is triggered to indicate either a high or low material level, depending on the application.

This method provides reliable and accurate level detection for bulk solids and powders in various containers such as silos, hoppers, and storage bins. The 3 Vane Rotating Paddle Level Switch is especially effective in industrial environments, ensuring consistent performance and durability in challenging conditions.
