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