Abstract: A monitoring system for monitoring wear and usage along a portion of a wear surface for earth moving equipment includes a monitoring assembly to detect a characteristic pertaining to wear or usage in a wear part for excavating equipment and transmit the detected characteristic as information, wherein the monitoring assembly includes a bolt having a standard head, a coupling nut that captures the bolt on one end, a spacer secured to the top of the head, and a sensor probe having an elongate structure that passes through both the bolt and the coupling nut and is captured by the coupling nut on an opposite end. The monitoring assembly being wirelessly able to communicate to a remote device to monitor wear.
