发明名称 Leak-testing technique for differential pressure sensor array
摘要 A leak-testing technique and apparatus for differential pressure sensor arrays is provided. A reference pressure sensor array is provided, wherein a seal is disposed between the reference pressure sensor array and a target differential pressure sensor array. A probe socket is utilized to communicate with each individual sensor in the reference pressure sensor array. The target pressure sensor array and the reference pressure sensor array are sealed via a pressure plate and plunger assembly. The target pressure sensor array, seal, and reference pressure sensor array are exposed to a first pressure. The target differential pressure sensor array, seal, and reference pressure sensor array are then exposed to a second pressure. The probe socket verifies that all reference pressure sensors continue to output the first pressure. If the probe socket identifies a reference pressure sensor that reads the second pressure, then the corresponding target pressure sensor is identified as being defective because of leakage.
