A conveyor has a metal detecting device for detecting metal parts in a conveying product, a magnet arrangement for producing a measuring magnetic field through which the conveying product is movable, a sensor device for registration a change of the measuring magnetic field, a signal evaluating device for evaluating a signal outputted by the sensor device in case of a magnetic field change, to recognize a metal part in the conveying product, and an interference sensor device which in case of a registration of an interference event, which leads to a magnetic field change caused not by metal parts in the conveying product and registered by the sensing device, outputs a faulty triggering warning signal.
