Abstract. Methodical uncertainties in measurements of unsteady surface temperature of massive bodies using various contact temperature converters are analyzed. Two approaches to the problem of actual temperature retrieving are considered: 1) based on Laplace transform application, leading to operational method of integration of arising differential equations, and 2) an approach using difference-differential models of heat transfer in the system of a thermocouple — object of the study that leads to a numericalanalytical calculation method.
Keywords: temperature, heat flux, measuring converter of temperature, indeterminacy of measurement, differential-difference models
