A sensor and method for measuring nitrogen oxide concentration |
| 摘要 |
<p>A small-sized inexpensive nitrogen oxide concentration sensor capable of measuring the concentration of the nitrogen oxide in a measuring gas to a high accuracy. A first oxygen pumping cell (6), an oxygen concentration measuring cell (7) and a second oxygen pumping cell (8) are formed in different solid electrolyte layers of zirconia and electrodes (7a,7b) of oxygen concentration measuring cell (7) are isolated from electrodes (6a,6b; 8a,8b) of the oxygen pumping cells (6,8) by insulating film (11-1,11-2). <IMAGE></p> |
