A Relationship between Resistance and Temperature of Thermistors

Abstract

The equation logR=A+B/(T+θ) for the resistance R of a thermistor at T°K is proposed. Least square analyses of the most precise resistance-temperature data available for three different thermistor materials show that the equation is a considerable improvement over its predecessors; the standard relative errors of fit are 0.4 percent, 0.17 percent, and 0.91 percent.
