摘要： A gas measurement system includes a sensor element and an associated electronic control unit (ECU) or the like connected thereto for receiving sensor element emf outputs. The ECU is configured to provide output signals or parameters indicative of ammonia and heavy HC gas concentrations. The sensor element has an NH3 sensor electrode output and a NOx sensor electrode output. The information conveyed by the NOx sensor electrode output may be selectively used by the ECU, in accord with so-called emf selection rules, to correct for a cross-interference effect that NO2 has on the NH3 electrode. Heavy HC gas concentrations may cause electrochemical activity on the NH3 electrode, and can be misinterpreted. A further emf selection rule is configured to detect the presence of heavy HC gas and is used by the ECU to suppress an output signal or parameter indicative of an ammonia gas concentration.

摘要： A single-cell sensor element is configured for ammonia gas sensing. The sensor includes an electrolyte layer, an NH3 sensing electrode and a NOx sensing electrode. The NH3 sensing electrode is sensitive to NH3 but is also vulnerable to cross-interference from NO2. To directly correct for this cross-interference, a second (NOx) electrode is provided and is used in a differential connection arrangement with the NH3 sensing electrode. The NOx sensing electrode has a first electrochemical sensitivity to NO2 that is greater than second and third electrochemical sensitivities to NH3 and NO, respectively. The NOx sensing electrode may have low or no sensitivity to NH3 or NO. The sensor element also includes first and second electrical leads respectively connected to the NH3 and NOx sensing electrodes. The output signal developed across the first and second leads is directly indicative of an ammonia concentration in a gas exposed to the NH3 and NOx sensing electrodes, thereby eliminating the need for emf selection rules to be programmed into an electronic controller to which the sensor is connected.
