working principle

When the conveyor belt is torn, punctured, damaged at the junction or protruded by sharp objects, the tear switch can provide an alarm signal to the monitoring personnel or close the conveyor. The tear switches are installed on both sides of the conveyor belt in pairs and are connected by two sections of aviation steel wire ropes with B jackets. One end of the aviation steel wire rope is fixed on the support bracket; The other end is connected to the pull ring of the tear switch, and the two sections of aviation steel wire rope form a monitoring surface under the conveyor belt. When the object or the torn belt is suspended and swept down to the aviation steel wire rope, the aviation steel wire rope pulls the pull ring of the tear switch to make it act, and the tear switch sends out an alarm signal or shutdown signal.
