Analizy porównawcze pomiarów temperatury powierzchni wykonano na podstawie wyników badań wykonanych na stanowisku badawczym z wymiennymi foliami ze stopów Haynes-230 i Hastelloy X, o różnych grubościach. Podczas eksperymentów realizowano pomiar temperatury metodą kontaktową (czujnikami rezystancyjnymi i termoelementami) oraz metodą bezkontaktową (dwie kamery termowizyjne). Tor pomiarowy zawierał termometr o wysokiej dokładności współpracujący z czujnikiem RTD 1/10 DIN (o klasie B) oraz kalibrator podczerwieni.

Comparative analyses of surface temperature measurements were performed based on research results obtained at a test station with exchangeable foils made of Haynes-230 and Hastelloy X alloys, varying in thickness. During the experiments, temperature measurements were carried out using the contact method (resistance sensors and thermocouples) and the contactless method (two infrared cameras). The measurement setup included a high-precision thermometer working with an RTD sensor (B class) and an infrared calibrator.

In this study, the uncertainty of measurement paths was estimated using selected statistical methods. Specifically, temperature measurements obtained from contact temperature sensors used in a heat transfer test section were investigated. The experiments utilized a dry-well temperature calibrator, thermoelements (types K, J, N, and T), and a data acquisition station. Additionally, a certified Pt-100 resistance sensor connected to the temperature meter was considered during measurements. The temperature range for the selected measurement points was 0.3 to 100 °C, covering both increasing and decreasing temperatures. To calculate the expanded uncertainty, both the uncertainty propagation method and the Monte Carlo method were employed. The results were analyzed and found to be similar.
