摘要: A calorimetric sensor for sensing hydrocarbon emissions in an exhaust gas emission monitoring system is provided with at least first and second areas coated with different first and second catalysts so that one catalyst coated area produces oxidation with HC, CO and H.sub.2 and the other catalyst produces oxidation with CO and H.sub.2 but not with HC. Temperature increases attributed to the oxidation reactions are sensed by first and second RTDs while the temperature of an uncatalyzed sensor area is sensed by a reference RTD. Thermal temperature signals for each first and second RTD is balanced against the reference RTD signal to produce accurate first and second temperature signals which are then subtracted to produce a true signal of the HC concentration in the exhaust gas.
