This is a general curve fitting equation to accommodate all NTC type resistors. The approximation of the relationship of temperature and resistance is “good enough” for most applications.
Webbspectral Thermometers since they respond in a discrete bandwidth. For common single bandwidth Thermometers there is a dilemma; there is one equation (Planck’s law) with two unknowns. The instrument receives the radiance (the energy), but it cannot solve for temperature without having an input value for target emissivity.
