Through the development of a thermocouple calibration device composed of a four-temperature zone measuring furnace,the continuous thermocouple is calibrated and uncertain evaluated,and the measurement characteristics of this type of sensor are understood and mastered.Finally,it is concluded that the overall offset of the continuous thermocouple to the K-type indexing table is corrected to+28℃,the extended uncertainty is 3.2℃,and the uniformity is(5-8)℃,which provides a technical basis for the correction of users and researchers.
