| Zusammenfassung | In this work, we present a mathematical procedure to evaluate a hydraulic gauge pressure comparison in the range to 1 GPa which was piloted by the Physikalisch-Technische Bundesanstalt. The comparison used a transfer standard consisting of two series of modern high-pressure transducers, i.e. eight pressure transducers in total. This set of parallel arranged transducers should ensure the reliability of the transfer standard at high pressures and provides rich data for testing the performance of modern high-pressure transducers. The analysis of the comparison results was based on the evaluation of the individual measurement deviations of these transducers with respect to the laboratory standards, whereas the corresponding comparison reference values and their uncertainty were determined separately at each pressure point and pressure transducer. All these results were summarized to derive the degree of equivalence for each laboratory at each pressure. The degree of equivalence was found to be consistent for all laboratories at almost all pressures. |
