The 2 Vane Rotating Paddle Level Switch is a robust and efficient device designed for continuous level detection of bulk solids and powders. Featuring two paddles mounted on a shaft that rotates at a fixed speed, this switch operates by measuring the resistance encountered when the paddles are obstructed by the material. When the material level rises and blocks one or both paddles, the rotational movement is hindered, triggering a switch to indicate high or low levels.
Ideal for applications in various industries, including food processing, agriculture, and chemicals, the 2 Vane Rotating Paddle Level Switch provides accurate and reliable level measurement in silos, hoppers, and storage bins. Its durable construction ensures long-lasting performance in harsh environments, while its design allows for simple installation and minimal maintenance, making it a practical choice for continuous level monitoring of bulk materials.

The 2 Vane Rotating Paddle Level Switch operates on the principle of mechanical obstruction. It features two paddles mounted on a shaft that rotates at a fixed speed. In the absence of material, both paddles spin freely without encountering resistance.
When the material level rises and comes into contact with one or both paddles, it creates resistance against the rotation. This change is detected by the internal sensing mechanism. If the paddles are obstructed for a specified duration, the switch is triggered to indicate high or low material levels, 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 2 Vane Rotating Paddle Level Switch is particularly effective in industrial environments, ensuring consistent performance and durability in challenging conditions.
