Conveyor belt arrangement including a conveyor belt having a hybrid conductor loop
A conveyor belt has a carrying side cover plate and a running side cover plate each of a polymer material having elastic properties. The conveyor belt defines a conveyor belt longitudinal direction (X) and has an embedded reinforcement and at least one of the cover plates is provided with a hybrid conductor loop. The hybrid conductor loop communicates in a contactless manner with an interrogation station in the form of a transmitter/receiver pair. The hybrid conductor loop has a flattened conductor cross section and runs in the conveyor belt obliquely at an angle (α) relative to the conveyor belt transverse direction (Y) to form a diagonal direction (Z). The transverse direction (Y) is at right angles to the longitudinal direction (X). The arrangement of the transmitter/receiver pair is adapted to the diagonal direction (Z) to so increase the mutual spacing of the transmitter and the receiver.
1. A conveyor belt arrangement comprising:
