Patent ID: 7493799

Claim:
A system that analyzes health of a lubricant in a machine, comprising: a component that senses, in situ, depletion of chemical additives from the lubricant while maintaining the lubricant at lubricating place, wherein the lubricating place is a bearing chamber and the component is positioned on a moving component of the bearing; an analyzer that compares the sensed depletion of the chemical additives of the lubricant with a pre-defined range of the chemical additives of the lubricant, wherein the result of the comparison is utilized to determine lubricant health, the analyzer is integrated with the bearing and is positioned on same base as the component; and a diagnostic component that maintains the lubricant in the machine by dynamically controlling qualitative and quantitative aspects of the lubricant based at least in part on the health of the lubricant to reduce at least one of lubricant degradation, depletion or oxidation.
