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).
