Abstract
The invention relates to a sensor system for in-situ monitoring of lubricant oil quality. The sensor system consists of a sensing element located in-situ in contact with lubricant oil. The sensor is corrodable and upon deterioration of the oil the sensor corrodes and eventually the circuit will break. Current flow through the circuit is monitored by conventional power supply and measuring devices and upon breaking of the sensor, an indication is provided to the driver of a motor vehicle indicating that oil is to be changed.
