Pressure gauge calibration applying 0-A-0 pressurization to reference gauge
A calibration method is proposed to improve pressure calibration that uses a pressure gauge as the reference device. The reference gauge is pressurized by a 0-A-0 pressurization procedure, whereas the test gauge can be pressurized through various procedures. The calibration results with this method were consistent with those calibrated against a pressure balance. The method is expected to help develop low-cost pressure calibration systems that are more precise.
