| 摘要 |
The present invention is a compact apparatus and method that provides an efficient manner for monitoring the condition and level of a functional flui d directly in operating equipment. A sensor device is provided that includes a plurality of liquid sensors and a plurality of vapor sensors that when used in conjunction with one another at different temperatures, can provide a thorou gh evaluation of the oxidative degradation, liquid contamination and solid contamination of the fluid to detect the end of the useful life of the fluid . By providing liquid sensors and vapor sensors on the same device, the presen t invention allows for a compact, efficient, and economically feasible manner to monitor the condition of fluid as well as detecting abnormal operating conditions prior to further component damage and eventual equipment failure.
