ABSTRACT:
An electrically responsive oil level sensor is mounted within a vehicle oil sump. An enclosure encloses the ends of two spaced electrodes. The high voltage electrode has a pointed end and the other low voltage electrode has a blunt end opposed to the pointed end. The low voltage electrode is connected to ground in series with an indicator. The enclosure has three vertically spaced openings. An entrance opening is aligned with the electrode gap for in flow of oil. A second is located below the entrance opening and establishes a restricted oil outflow. The third opening is above the entrance opening for air and fume escapement. A baffle is interposed between the entrance opening and the electrode gap. The baffle prevents the motion of the oil in the sump from moving directly through the entrance opening and into the electrode gap. The enclosure has an integral tower for the high voltage electrode and the tower has annular radial projections to increase the surface creepage path.
