Abstract
A wear sensor () installed on a surface area () of a component () subject to wear from an opposing surface (). The sensor has a proximal portion (A,A,A) and a distal portion (C,C,C) relative to a wear starting position (). An electrical circuit () measures an electrical characteristic such as resistance of the sensor, which changes with progressive reduction of the sensor from the proximal portion to the distal portion during a widening reduction wear of the surface from the starting position. The measuring circuit quantifies the electrical changes to derive a wear depth based on a known geometry of the wear depth per wear width. In this manner, wear depth may be measured with a surface mounted sensor.
