ABSTRACT:
A lubricant filtering and monitoring system and method is provided for a lubricant circulation system circulating lubricant through a filter to a lubricated component. A combination of sensors senses a condition of the lubricant before and after passage through the filter and before and after passage through the component and provides an output indicative of a condition in the circulation system. A sensor senses a condition of lubricant flowing through the filter, and another sensor senses a condition of lubricant flowing through a reference section for comparison against and normalizing of the output of the first sensor. A method of actively monitoring the component is provided by comparing influent to the component with effluent from the component to ascertain how lubricant is being modified by the component, by sensing a condition of lubricant passing through the filter. An effective method is provided for determining when to change or clean the filter. A diagnostic method is provided for assisting in such determination and diagnosing lubricant condition, filter condition and component condition.
