Development of 1.6 GPa pressure-measuring multipliers

Wladimir Sabuga, Rob Haines

Abstract


Two 1.6 GPa pressure-measuring multipliers were developed and built. Feasibility analysis of their operation up to 1.6 GPa, parameter optimisation and prediction of their behaviour were performed using Finite Element Analysis (FEA). Their performance and metrological properties were determined experimentally at pressures up to 500 MPa. The experimental and theoretical results are in reasonable agreement. With the results obtained so far, the relative standard uncertainty of the pressure measurement up to 1.6 GPa is expected to be not greater than 2·10-4. With this new development the range of the pressure calibration service in Europe can be extended up to 1.5 GPa.
