This paper introduces an on-line condition monitoring of lubricant degradation for oil-lubricated machinery. The system detects the relative variation of lubricant degradation i.e., physical/chemical properties, generated wear particles and ingested contaminants, by using the grid capacitance sensor in an on-line installation. The system consists of grid sensing unit and a multitude of small holes (up to 2mm. in diameter) between the sensing grids. The oil enters in the top part and flows through the holes and exits at the bottom. In addition, the sensor can also detect large size "metal" particles i.e., whereas the component being monitored approaches catastrophic failure which cannot be detected by the conventional on-line "Ferrous Debris Monitoring Sensor" such as the Magnetic Chip Detector (MCD). In addition, the system can also be used to distinguish the relative variation of the dielectric constant of lubricant caused by contaminants such as water, fuel dilution, etc.
