Information-measuring System to Study the Thermocouple with Controlled Temperature Field

open access: yesMeasurement Science Review, 2019
Error due to inhomogeneity is the main problem of thermocouples (TCs), e.g., during the operation of a type K TC, this error can reach 11-30 °C. Thus, metrological reliability of TCs is threatened by this error because there is a high risk of exceeding ...
