Abstract
A conveyor belt scales for transporting goods includes: a feed belt; a weighing belt; and a removal belt. The weighing belt is supported on a load cell that detects a weight of the goods transported by the weighing belt. The conveyor belt scales further has a metal detector, which includes a transmitter coil and a receiver coil. The transmitter coil and the receiver coil are each a planar coil.

A conveyor belt scales for transporting goods, the conveyor belt scales comprising:
- a feed belt;
- a weighing belt;
- and
- a removal belt,
- wherein the weighing belt is supported on a load cell that is configured to detect a weight of the goods being transported by the weighing belt,
- wherein the conveyor belt scales further comprise a metal detector that comprises at least one transmitter coil and at least one receiver coil,
- wherein the at least one transmitter coil and the at least one receiver coil are each configured as a planar coil,
- wherein the metal detector further comprises a signal generator that is configured to generate an AC signal that is fed to the at least one transmitter coil,
- wherein the AC signal fed to the at least one transmitter coil is configured to generate a magnetic field that induces eddy currents in a metal object that is to be detected in a good on the conveyor belt, and
- wherein the metal detector further comprises a signal evaluator that is configured to detect a magnetic field generated by the eddy currents in the metal object in the good and received by the receiver coil.
