Abstract: A wear sensor system for detecting erosion, corrosion and wear of a component is disclosed. Conductive loops of a sensor probes are embedded at spaced locations through the component. As erosion, corrosion or wear of the component is sustained, each conductive loop is subjected to such wear condition in turn and is interrupted only as the component is worn away at its particular location. The continuity status of each loop is evaluated periodically, with an electrical closed circuit condition indicating structural integrity at that particular loop location, and an electrical open circuit condition indicating such a wear condition.
