Abstract
A method of calibrating temperature of a resistive element having a material with a Curie temperature includes generating a standard resistance-temperature (R-T) curve for the resistive element in isothermal conditions to identify values of the R-T curve and an inflection point at the Curie temperature, generating operational R-T curves for the resistive element over an operational time period, comparing the standard R-T curve to the operational R-T curves, and adjusting the operational curves to the standard R-T curve at the Curie temperature to calibrate temperature of the resistive element.
