ABSTRACT:
The present invention provides a chain wear monitoring device for monitoring chain wear in a chain drive conveyor system. The chain wear monitor electronically measures, calculates, records, and reports the amount of chain wear along the entire length of the conveyor chain. The monitor calculates the wear as the number of inches per nominal ten foot section of chain. A large diameter measuring wheel is rotatably mounted on a shaft extending from the monitor control box. An encoder connected to the wheel is used measure the distance of the chain and a proximity sensor counts the links. A magnetic assembly may be fixed to the chain to cause the monitor to automatically start and stop a data recording session for a chain on a conveyor system at the same spot each time the chain is monitored, facilitating section by section comparison of chain wear.
