Abstract: A conveyor belt (8) and method for monitoring a moving conveyor belt (8), the conveyor belt (8) having a first edge region (2), a second edge region (4), and a load carrying region (6). The method functions to detect belt edge damage, changes in belt width, and changes in belt tracking by monitoring a magnetic field associated with a plurality of edge detection inserts (1,3) embedded within the conveyor belt (8). In one embodiment this is achieved by monitoring images of the magnetic field associated with the edge detection inserts (1,3) embedded within the conveyor belt (8). The method may utilize a magnetic sensor system to detect magnetic images of the edge detection inserts (1,3) where the edge detection inserts (1,3) are positioned longitudinally along the length of the conveyor belt (8) in the first edge region (2) and the second edge region (4) of the conveyor belt (8).

Abstract: A system is for monitoring a conveyor belt configured to be used as an at least partially enclosed belt conveyor and defining a longitudinal direction. An antenna is embedded in the conveyor belt and extends in the longitudinal direction. The system includes a transmitter for inducing an electrical field in the antenna and a detector for detecting the electrical field induced in the antenna. The transmitter and the detector are arranged in a spaced relationship with respect to the longitudinal direction so as to reduce cross talk between the transmitter and the detector. The conveyor belt is configured to move in the longitudinal direction and convey the antenna past the detector and the transmitter. The spaced relationship and the length of the antenna are mutually configured such that the antenna couples the transmitter to the detector longitudinally as the antenna moves past the detector and the transmitter.
