| titleOfInvention | Sensor for measuring concentration of nitrogen oxide and detecting ammonia slip |
| abstract | The present invention relates to a gas sensor and, more specifically, to a gas sensor capable of measuring the concentration of nitrogen oxide and detecting ammonia slip. The present invention provides a sensor for measuring the concentration of nitrogen oxide and detecting ammonia slip, comprising: an oxygen ion-conductive solid electrolyte; a first electrode coming into contact with the solid electrolyte, and being reactive with nitrogen oxide; a second electrode coming into contact with the solid electrolyte, separated from the first electrode, and being reactive with nitrogen oxide; a third electrode coming into contact with the solid electrolyte, separated from the second electrode, connected in parallel with the first electrode, and being reactive with ammonia; a power supply device formed so as to apply power between the second electrode and the first electrode and third electrode, which are connected in parallel with each other; and a measurement device formed so as to measure the potential difference or the current between the first electrode and the third electrode, which are connected in parallel with each other, and the second electrode. According to the present invention, the sensor for measuring the concentration of nitrogen oxide and detecting ammonia slip can simultaneously measure nitrogen monoxide and nitrogen dioxide. In addition, whether ammonia is discharged can be simultaneously measured. According to the present invention, manufacturing costs of the sensor for measuring the concentration of nitrogen oxide and detecting ammonia slip are reduced since a nitrogen oxide sensor and an ammonia sensor share a part of the electrodes, the solid electrolyte, a heating part and the like. In addition, installation costs are also reduced since the nitrogen oxide sensor and the ammonia sensor do not need to be separately installed. |
