摘 要：

The present invention relates to a NOx sensor, the output direction of the sensor signal for nitrogen monoxide and nitrogen dioxide is equal to about the total amount of the nitrogen oxide in the nitrogen oxide sensor which can be measured more

accurately and to respond only to nitrogen dioxide according to the method of

forming the oxide sensing electrode. ; The nitrogen oxide sensor of the present invention ( 100) is an oxygen ion conductive solid electrolyte (10); The oxygen ion conductive solid electrolyte (10) detects at least one oxide which is formed on the electrode 20; A first noble metal electrode 30 is formed on the oxide sensing electrode (20); The second noble metal electrode 40 formed on the oxygen-ion conductive solid electrolyte (10); And is made of the oxide sensing electrode 20 and second noble metal electrodes 40 electrically connected to the electromotive force and to extend the lead wire 50, the oxide sensing electrode 20 and second noble metal electrodes 40 are connected in parallel is characterized in that the.

摘 要 附 图：

Accordingly, ;, the nitrogen oxide sensor of the present invention measures the amount of nitrogen oxide in the same direction, the output signal of the sensor to a high temperature and a low

concentration of bad conditions on the nitrogen monoxide and nitrogen dioxide or nitrogen dioxide reacts only and more accurate measurement and the nitrogen dioxide concentration can be stably determined. ; In addition, the nitrogen oxide sensor of the present invention using a sensor can measure the concentration of the nitrogen dioxide sensor, and can measure the

concentration of total nitrogen oxide The effects that can be injected in a catalytic amount of a precise amount of nitrogen is by calculating the concentration reduction apparatus of the nitrogen monoxide and nitrogen dioxide. 主权项：
