  • Method for improving accuracy of sensor outputs for measuring NOx, and system and apparatus for same
    Patent number: 10620174
    Abstract: A method, system, and apparatus are provided for improving accuracy of sensor readings reflecting measurements of at least one constituent in an engine exhaust. The sensor measurement is corrected or compensated for by applying to a gain correction factor to the reported sensor measurement. The gain correction factor is developed by determination of prior test sensor readings correlated with discrete sensor age levels, and with constituent concentrations to which those test sensors are exposed. By applying the determined gain correction factor to change the sensor's reported measurements, bias may be reduced and a more accurate measure of actual constituent levels is provided.
