摘要：A method and apparatus for determining the effectiveness of bearing seals in s roller cone drill bit. The bit includes a sensor in optical communication with the bearing lubricant. The sensor includes a light source, an optical filter, and an optical detector arranged so that light interacts with the lubricant, is filtered, and detected, wherein the detected light is indicative of the amount of contaminant within the lubricant. The optical filter is preferably an integrated computing element that filters preselected orthogonal components from the light.
