| Zusammenfassung: | The reliability of a pressure sensor is improved either by utilization of redundant composants. A pair of pressure sensors are mounted upon a single pressure sensor diaphragm. The pressure signals generated by the pressure sensors are compared and, if the difference between the signals exceeds a predetermined threshold, it is determined that a malfunction of the pressure sensor has ocurred. Alternately, additional diagnostic testing may be included to detect a malfunctioning sensor. |
