Abstract: An oil level sensor includes a sensor body adapted to be mounted to the block or casing of an oil-containing reservoir. A probe including a pair of electrodes forming a capacitor extends from the sensor body so that the capacitor will be at least partially immersed in the oil to detect the level thereof. At least one of the electrodes is insulated so that the apparent capacitance of the capacitor is relatively insensitive to any change in the conductivity of the oil at high temperatures. Circuitry is provided in response to the capacitance of the capacitor for signalling the level of the oil, which capacitance is a function of the oil level. The sensor body is mounted to the block by external threads on the probe. The electrodes of the probe extend proximally past the threads to provide an increased capacitance for the sensor. The electrodes of the probe are concentric and the inner electrode is supported at both ends to reduce fatigue.

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 primary and secondary pump system of the prior art lube oil system normally includes a primary centrifugal pump affixed to the turbine shaft and ac and dc motor-driven pumps to supply lubrication during start-up and shutdown when the primary pump cannot maintain flow due to low rotational speed.

The pump is in parallel with a primary check valve in the lube oil feed line, so that the positive displacement backup lube oil pump is supplying oil at all times to the shaft bearing.
