Temperature Plotting Apparatus
In the engineering development of cryogenic electronic equipment various device and material characteristics must be measured as functions of temperature, usually in the helium range. Most of these measurements are concerned with superconductivity and involve resistance, critical field, and critical current as functions of temperature. The classical U-tube mercury manometer, while quite accurate, does Involve a time consuming multiple reading, a pressure calculation, and a nonlinear conversion to temperature before data plotting may begin.
