Abstract
A method for determining when to change a lubricating fluid flowing within an apparatus includes monitoring the lubricating fluid flowing within the apparatus by passing radiation through the lubricating fluid from a radiation source. The lubricating fluid is analyzed for a presence of particles in the lubricating fluid based on the radiation passing through the lubricating fluid. A concentration of the particles in the lubricating fluid is determined when the presence of particles is detected. An alert to change the lubricating fluid is generated when the concentration of particles in the lubricating fluid exceeds a threshold.
