Automating the Calibration of Two Piston Gage Pressure Balances

Abstract
We propose a method to automate the data-gathering process in the cross-float calibration of one piston gage pressure balance against a second piston gage pressure balance. Rather than adjusting small trim masses until the balances generate equal pressure, the two balances are brought into only approximate pressure equilibrium. They are then sequentially connected to a pressure transducer, through use of constant volume valves, to measure the differential pressure. We present results of the method on a 200 MPa hydraulic system. We explore limitations to the method, including the allowable pressure difference between the two pressure balances, the sequencing procedure of the pressure balances, and the characteristics of the pressure transducer.Citation
