| Abstract: | A general air tightness testing facility based on the principle of differential pressure with the ARM processor as the control core was designed.It carries out charge-discharge progress via controlling air control valve and gets the differential pressure value through the high accuracy differential pressure sensor.The system s human-computer interface uses the touch-screen module.The testing result shows that this facility has high testing accuracy and good stability. |
