Abstract
The theory of a composite resistance thermometer, consisting of platinum in series with a second metal which will compensate the nonlinear resistance-versus-temperature characteristic of the platinum, is developed. Gold and rhodium are suggested for the second metal. The theory and advantages of the approach, which uses overcompensation of the curvature of platinum plus subsequent linearization by means of fixed external resistance, are presented.
