Abstract：In order to solve the problems of incomplete,slow and inaccurate performance testing NOx sensor,the structure,working principle and control process of NOx sensor are analyzed,and combined with the current status of testing technology,an automatic performance testing for NOx sensor is designed.This device optimizes the dynamic gas mixing method,the automated structure testing module and the data processing module to solve the problems of"slow"and"incomplete"testing,but the accuracy of the detection results and the stability of the system should also be improved.
