ABSTRACT A modification to the conveyor belt monitoring of Australian Patent No. 535,356 (to which U.S. Patent 4,439,731 corresponds) is disclosed. In this modification the belt cords are first de-gaussed to remove any stray magnetic fields, and then longitudinal unidirectionally magnetised. The belt is then scanned in accordance with the abovementioned Patent but the electrical output signal is passed through a low pass filter in order to produce a break signal indicative of breaks in the magnetically permeable cords of the conveyor belt. Apparatus for carrying out the above described method is also disclosed.
