SOLID-STATE AUTOMOTIVE LIQUID LEVEL SENSING SYSTEM
A method capable of distinguishing between the presence and absence of liquid at a discrete level by monitoring the rate of heat transfer from a solid-state sensing element is discussed; a detailed description is given of the silicon sensor and the associated electronic circuitry. Three versions of the systems are described, each suited for different types of level sensing applications. Suggested among the possible uses are a number of automotive applications such as crankcase, transmission, and brake fluid measurements.
