ANALYSIS AND AUTOMATED TESTING OF A MINIATURE PNEUMATIC VALVE FOR HOSPITAL PATIENT SUPPORT EQUIPMENT
Keywords:
miniature pneumatic valve, automated testsystem, valve characteristicsAbstract
The steady state and dynamic performance of a miniature pneumatic valve is studied and an automated, computercontrolled test procedure is developed to determine unwanted leakage. A novel testing approach is developed using the valve dynamic leakage characteristic, and a substantially reduced test time has been achieved. A National Instruments LabVIEW hardware approach is utilised for both data acquisition and real time control and the test procedure has been put into commercial use.
