Abstract:
A modified noble metal catalyst based calorimetric sensor for sensing non-methane hydrocarbons in an automotive exhaust gas stream includes a first sensing element (105) with an output that provides a signal (111) indicative of a concentration of indicative of non-methane hydrocarbons, hydrogen (H. sub. 2), and carbon monoxide (CO). A compensating sensing element (107) has an output that provides a compensating signal (113) indicative of a concentration of hydrogen (H. sub. 2) and carbon monoxide (CO). A circuit for combining the signal and the compensating signal provides a combined signal indicative of a measure of non-methane hydrocarbons in the automotive exhaust gas stream.
