Low temperature calibration of Manganin pressure gauges.

Summary

High pressures are often measured using the resistance of Manganin wires. However, the pressure coefficient of resistance is known to depend on temperature. The authors have measured this temperature dependence by comparing the output from a Manganin gauge with that of a well calibrated Zeranin gauge and determined a correction factor which enables them to measure the pressure at any temperature between 150 and 300 K with a temperature dependent error well below 0.5%.
