An investigation was undertaken to develop an abrasive oil contaminant indicator for use on the M35A2 2 1/2 ton and the M151A2 1/4 ton trucks. This included quantitative determination of the characteristics of abrasive lubricant contaminant, the development of a concept to detect and indicate the presence of the abrasive particles, the design, fabrication and testing of a device to implement this concept in a practical manner. The sensor developed employs a thin metallic coating on a non-conducting quartz substrate which is abraded by the action of the abrasive particles in the lubricant. The extent of the wear is indicated by an increase in the electrical resistance of the path due to the reduction in the cross sectional area of the metallic conducting path. Excessive abrasive action actuates a warning light in the cab of the vehicle through an electronic circuit. The warning signal persists until the wear element is changed.
