    Fabrication and Calibration of Pt-Rh10/Pt Thin-Film Thermocouple by Fengxiang Wang, Zhenyu Lin, Zhijie Zhang, Yanfeng Li, Haoze Chen, Jiaqi Liu, Chao Li

    Published 2022-12-01
    “…In the testing process, the static calibration of the thermocouple at 50~600 °C and 650~1500 °C was completed by a portable temperature verification furnace and a horizontal high temperature verification furnace, and the results showed that the Seebeck coefficient of the thermocouple was about 10.70 μV/°C, and its output voltage–temperature curve was similar to that of a standard S-type thermocouple, which achieved the effective temperature measurement up to 1500 °C. The dynamic response of Pt-Rh10/Pt thin-film thermocouple was then tested and studied using the pulsed laser method, and the results show that the time constant of the thermocouple prepared in this paper is about 535 μs, which has the characteristics of fast response and high precision high-temperature testing. …”
