Electromagnetic induction method. Transmitter and receiver sensors detect whether loop coils embedded in the bottom cover rubber of the conveyor belt have been cut.
In the event of longitudinal rip in the conveyor belt, signal generated by the loop coil will not pass between the transmission and receiving sensors, shutting down the conveyor system.
Rip Sensors are normally incorporated in the tail section of the belt . Dual detectors can be incorporated in the tail and head sections
