Abstract
A system for detecting wear in a gripper chain of a chain conveyor is provided. The system includes an optical sensing system having a detection path located vertically beneath a portion of the gripper chain at a predetermined location. The detection path is located such that, when the gripper chain becomes elongated and droops a predetermined amount due to wear of the gripper chain, the sensing system senses the presence of the gripper chain in the detection path.
