METHOD FOR MEASURING TEMPERATURE

摘要

The proposed method for measuring temperature of an object consists in measuring the conditional temperatures of the object by a pyrometer and determining the real temperature of the object by the data obtained in measuring the conditional temperatures. The method is distinctive by measuring three color temperatures that correspond to three or more colors of the thermal radiation spectrum of the object and determining the real temperature of the object as a mean arithmetic value of the said color temperatures. The proposed method provides a possibility to increase accuracy in determining temperatures of objects with unknown variable emissitivity factors due to the decrease of the measurementtruncation error that is achieved through measuring color temperatures that are symmetrical relative to the real temperature.
