Abstract
An apparatus for monitoring the condition of a lubricating medium includes a UV light source, a UV receiver, a processor electrically coupled to both the UV light source and the UV receiver, and a memory device electrically coupled to the processor. The memory device has stored therein a plurality of instructions which, when executed by the processor, cause the processor to (a) communicate with the UV light source and the UV receiver so as to expose a sample of the lubricating medium to the UV light and generate a UV spectrum of the sample in response thereto, and (b) compare the UV spectrum of the sample to a model spectrum and generate a control signal if the UV spectrum of the sample has a predetermined relationship to the model spectrum.
