INTEGRATED OIL CONDITION AND LEVEL SENSOR

摘要

An oil condition and level sensor is provided that includes a solenoid body, a coil, an armature and a pole piece. The solenoid body defines an armature chamber between the armature and the pole piece. The armature is movable in the armature chamber in response to energizing of the coil. In an oil condition sensing system, the coil is operatively connected to a controller which can determine at least one of an oil temperature, oil viscosity, oil level, and an oil change occurrence. In one embodiment, four oil levels, including an overfill oil level and an excessively low oil level maybe detected. The sensor is referred to as an integrated oil condition and level sensor as multiple sensing functions are integrated into one sensor.
