A new type of Ratiometric Temperature Sensor has been developed which shows considerable promise in the measurement of engine intake manifold fuel/air charge temperatures. The device consists of a conductive plastic potentiometer, driven by an integral bimetallic sensing element. The Ratiometric Temperature Sensor closely tracks the rapidly fluctuating temperature of the fuel/air charge, and provides a linear ratiometric output voltage ranging from 15% to 85% of the total supply voltage over the sensed temperature range of -40°C to +125°C. Output accuracy is ±3°C over a temperature range of +20°C to +100°C.
