ABSTRACT:
The reliability of a pressure sensor is improved either by utilization of redundant components. A pair of pressure sensors are mounted upon a single pressure sensor diaphragm. Each of the pressure sensors is connected to one of a pair of signal conditioning circuits. The gain of one of the signal conditioning circuits is a fraction of the gain of the other signal conditioning circuit. The outputs of each of the signal conditioning circuits are compared to a corresponding threshold. If both of the output signals exceed the corresponding threshold, it is determined that a malfunction of the pressure sensor has occured.
