Continuous monitoring of feed conveyor belt for damage

摘要

The condition of a feed conveyor belt (2) that can be up to hundred of meters long is continuously monitored to detect early warning of damage that can lead to a major failure. The belt is constructed with embedded IC transponder chips (10) at intervals along an across the belt. The transponders respond to a transmitter/receiver (20) via an inductive path provided by coil elements(22). Each transponder has an individual identification code that is received by a processor (26) and the location determined.
