1.1 K – type Thermocouple
[Figure 1] coefficient values depending on thermocouple types
For precise measurements, the temperature difference as a function of the output voltage can be approximated by a polynomial. The [Table 1] shows the coefficient values of K-type thermocouple.
Where the average deviation was 1.53℃, the calibration was completed by adding the corresponding value to the entire interval. The average error before calibration is 2.7%, and the average error after calibration is 1.13%. It can be said to be relatively effective because it can reduce the error rate by more than half.
Where the average deviation was -4.38℃, the calibration was completed by adding the corresponding value to the entire interval. The average error before calibration is 8.84%, and the average error after calibration is 0.53%. It can be said to be a very effective calibration method because the error rate can be reduced to less than 1%.
