Estimation of inaccuracies of Thermocouple measurements of the temperature profile in pyrolyzed solid substances
Thermophysics and Aeromechanics, 2010Co-Authors: A. D. Rychkov, V. E. Zarko, V. D. Liseikin, A. V. KofanovAbstract:Thermal interaction of a Thermocouple embedded into a solid substance pyrolyzed by an external heat source with the thermal wave propagating inward the substance from the pyrolysis surface is considered. Numerical simulations show that a heat sink through Thermocouple wires inward the substance occurs because of a significant difference in thermal conductivities of the solid substance and Thermocouple Material, which leads to substantial changes in thermojunction, thus, distorting Thermocouple data.

Inaccuracy estimation of Thermocouple measurements of temperature profile in pyrolyzed solid substances
2010Co-Authors: A. D. RychkovAbstract:The work considers interaction of Thermocouple embedded in the solid substance pyrolyzed by external heat source with heat wave propagating inside the substance from the surface of its pyrolysis. Numerical simulation has shown that significant difference in the values of thermal conductivity coefficients of solid substance and Thermocouple Material results in the heat flow along Thermocouple wires inside the substance that substantially changes thermojunction temperature thus misrepresenting Thermocouple data.

A measurement system of high-temperature oxidation environment with ultrasonic Ir0.6Rth0.4 alloy thermometry.
Ultrasonics, 2018Co-Authors: Gao Wang, Lin Xu, Miao Tian, Dongfang Yuan, Hanchang Zhou, Lu YangAbstract:Abstract Iridium-rhodium is generally applied as a Thermocouple Material, with max operating temperature about 2150 °C. In this study, a ultrasonic temperature measurement system was designed by using Iridium-rhodium (60%Ir–40%Rh) alloy as an acoustic waveguide sensor Material, and the system was preliminarily tested in a high-temperature oxidation environment. The result of ultrasonic temperature measurement shows that this system can indeed work stably in high-temperature oxidation environments. The relationship between temperature and delay time of ultrasonic thermometry up to 2200 °C was illustrated. Iridium-rhodium Materials were also investigated in order to fully elucidate the proposed waveguide sensor’s performance in a high-temperature oxidation environment. This system lays a foundation for further application of high-temperature measurement.
