FÖRDERER MIT EINER METALLDETEKTIONSEINRICHTUNG

摘要

Conveyor comprises a metal-detecting device (18) for detecting metal parts in a conveyed product. The device consists of a magnetic arrangement (19) producing a measurement magnetic field (M) through which the product is moved, a sensor arrangement (21) registering a change in the measurement magnetic field, and a signal evaluation device evaluating a signal generated by the sensor arrangement to identify a metal part. An interference sensor unit (26) generates an error warning signal on registering an interfering event leading to a change in the magnetic field not caused by metal parts. - Independent claims are also included for: - (1) Harvesting machine comprising the above conveyor; and - (2) Process for detecting metal parts in a conveyed product.
