【Abstract】 On the basis of working principle of current limiting oxygen sensor,the computation formula of the sensor’s electrical performance index is derived and the accurate formula is given. Kit assembled dynamic gasmeasuring system is adopted to research electrical property measuring method. The measurement of the error and responce time of the sensor is realized. The results show that it is accurate,and the response time is no more than 5s. It has practical characterizstics.更多还原
