APPLICATION OF 0-A-0 PRESSURIZATION TO PRESSURE GAUGE CALIBRATIONS

摘要

A new calibration method is proposed and examined to improve the pressure calibration using pressure gauges as the reference device. In the method, the reference gauge is pressurized with the 0-A-0 procedure, while the test gauge can be pressurized with various procedures. The calibration results with this method were found to be consistent with those calibrated against a pressure balance. The method is expected to help develop more precise and low-cost pressure calibration systems.
