Feature: 1. Automatic Alarm Activation: The blocking coal switch is strategically installed on the sidewall of the chute. When a blockage occurs, the accumulated material compresses the movable door, activating a travel switch. This mechanism promptly triggers warning or shutdown signal, ensuring that equipment issues are addressed quickly to prevent further damage. 2. Self Resetting Mechanism: Featuring a pressure actuated structure, the chute blockage detector utilizes a compression spring that automatically resets the movable door once the blockage is cleared. This self resetting feature enhances operational efficiency, allowing for minimal downtime and quick return to normal operating after resolving the issue. 3. High Performance Micro Switch: The blockage detector chute switch is equipped with a high performance micro switch that boasts quick responsiveness and high reliability. This ensures accurate detection and timely alerts every time a blockage occurs, contributing to overall system safety and operational effectiveness. 4. Easy Installation: With a compact profile, the circular chute blockage detector is designed for convenient installation in various locations. Its small size allows it to fit seamlessly into existing systems without requiring significant modifications, making it easy to integrate into your operatings. 5. Rugged: Built to withstand operational demands, the coal anti blocking switch ensures long lasting performance even in challenging environments. Its robust design reduces maintenance needs and minimizes the risk of false alarms, making it a dependable solution for effective blockage detection in chutes and conveyors.
