Abstract
The invention relates to a system for monitoring a layer (8), which is subjected to wear, of a composite structure (2) and relates especially to a system for monitoring the cover layer (8) of a conveyor belt (2). The monitoring system includes a transmitter/receiver device (4) which continuously generates an electromagnetic field. A ferromagnetic layer (16) of high permeability is embedded in the cover layer (8) and shields a transponder (6), which is embedded in the conveyor belt (2), from the electromagnetic field as long as it is not damaged by wear. The transmitter/receiver device (4) recognizes the wear of the cover layer (8) in that it receives data from the transponder (6) because, in this case, the ferromagnetic layer (16) is damaged over a large area. The invention also relates to a method for monitoring a composite structure (2) having a layer (8) subjected to wear. The invention relates especially to a method for monitoring the cover layer (8) of a conveyor belt (2).
