Abstract
The performance of manganin resistance gauges under high static pressure is evaluated. The accuracy of several interpolation- (or extrapolation-) based mathematical-models is compared. It is shown that if the gauges used at pressures below 1 GPa are calibrated at a given constant temperature and used at that temperature, the complete mathematical-model is unnecessary. However, a complete model for the variation of resistance with both pressure and temperature is required in the pressure range from 1 GPa up to 20 GPa, because the temperature changes due to compression or expansion of the pressure-transmitting medium can be quite pronounced.<>
