Thermal inertia and finite heat conduction make the acquired temperature from temperature sensor be not reliable enough. So, it is necessary to make a dynamic calibration to the sensor. The frequency-response characteristics of high speed radiation thermometer surpass that of the temperature sensor; therefore it can be used as the reference value to calibrate the latter and let system error is corrected. The traceable dynamic calibration method is used to calibrate CHAL-010 thermocouple (manufactured by OMEGA Company). The thermocouple's time constant as well as error correction value of dynamic temperature measurement is obtained from it. The traceability is accomplished successfully through unbroken chain of comparisons with appropriate standard at the system.
