Penyelesaian kepada ralat suhu relau elektrik eksperimen

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: sisihan suhu, ℃;

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

t0: Nilai purata n ukuran termokopel piawai pada titik tengah, ℃.
