ABSTRACT:
An oil contamination detection assembly includes a housing adapted for installation into a vehicular pneumatic brake system having a supply of air contaminated with oil. A surface is disposed within the housing for communicating with the air of the brake system and accumulating a film of the oil contaminating the air. A sensor directs a wave, such as an electromagnetic wave, having a predetermined characteristic at the surface, receives a wave reflected from the surface having a characteristic altered by the film of oil accumulated on the surface, and produces an oil contamination warning signal based upon the altered characteristic of the reflected wave.
