Abstract :
The high-static-pressure metrological characteristics of 1-GPa manganin resistance gauges are investigated. Nonlinearity is measured by means of a secondary standard-free piston gauge. A second-order mathematical-model is established, with an interpolation accuracy reaching 0.07%, as verified by calibration tests. The results obtained indicate that manganin resistance gauges exhibit very good stability, repeatability, and reproducibility
