The electrical resistance of a manganin coil was measured at various temperatures and pressures in the ranges of 20 to 200°C and 0 to 7 kbar. Three useful results were obtained from this study. (1) At elevated temperatures, the resistance of the manganin coil is reproducible with rising and falling pressures. (2) At elevated temperatures, the resistance‐pressure curves remain linear. (3) The pressure coefficient changes only slightly with temperature. The present study indicates that the manganin coil may be used as a pressure indicator at elevated temperatures, provided that a convenient correction due to the shift of the resistance at different temperatures is made.
