Abstract
The work presents a numerical approach for the evaluation of uncertainty in calibration systems for contact temperature sensors. This type of measurement is widely used in practice, but its results are influenced by systematic errors due to the interaction between sensor and measured surface. The uncertainty of the system is evaluated through the numerical simulation of its temperature field, when the sensor to be calibrated is placed on the reference body’s surface. The procedure is validated on the basis of a simulation carried out for two calibration systems, for which the experimental data are available in literature.
