의 온도 오차에 대한 솔루션 실험용 전기로

First insert the standard temperature measuring thermocouple into the unfilled experimental electric furnace, and its test point should be at the center of the experimental electric furnace, then set the temperature control instrument to the required nominal temperature, and then make the experimental electric furnace perform In normal heating work, the calibration staff records the temperature of all pilots every 2 minutes through the standard instrument, and records 15 times within 30 minutes. After that, the measured value is compared with the original value, and the data is obtained after data processing. The deviation value, the calculation formula is as follows: △t=td-t0

△t: 온도편차, ℃;

td: the average temperature displayed by the temperature control instrument of the tested experimental electric furnace, ℃;

t0: 중심점에서 표준 열전대의 n 측정값의 평균값, ℃.
