Improvement of Accuracy of Measuring Temperature during Bench-test of Radiation Heating of Construction Elements Made of Low Heat-conduction Materials

The influence of some parameters on the methodical error of measuring the temperature using a thermocouple sensor is investigated for the following: density of the incident heat flow, misalignment of the thermocouple location in the recess of the construction element under study, thermal and physical properties of the material filling the recess. The obtained investigation results allow one to improve the accuracy of measuring the temperature during the heat testing of construction elements.
