ABSTRACT:
An oil level sensing apparatus has a body which defines a volume having an open bottom. A float in the volume supports a permanent magnet and moves within the volume in accordance with the oil level therein. A reed-switch is affected by the magnet supported on the float to detect a low oil level. A temperature sensitive plate closes the open bottom of the volume at low temperatures in order to prevent false readings. Additionally, in order to prevent false readings during transient oil level fluctuations at higher oil temperatures, a spring opposes the opening of the plate such that a restriction is formed in the path for draining oil from the volume. This delays the oil drainage from the chamber and any resulting low oil level signal.
