    Abstract: In order to meet the needs of accurate temperature measurement of superconducting DC energy pipelines, and to ensure the goal of hybrid transport of superconducting power and liquefied natural gas. In this paper, a low-temperature platform is designed to study the temperature sensing characteristics of the fiber grating sensor in the temperature region of mixed working fluid (85~90 K), and the temperature of the fiber grating is accurately calibrated by PT100 platinum resistance, and the maximum deviation of the measured temperature deviation is less than 0.1 K. Furthermore, a 10 m prototype of a superconducting energy pipeline is constructed and tested under various flow conditions. The results show that the temperature measurement by PT100 platinum resistance experiences significant fluctuations, whereas the fiber grating sensors remain unaffected. In the process of sudden temperature rise, the average response time of PT100 platinum resistance is 2.43 s, and that of fiber grating sensor is 0.47 s.
    Key words: superconducting; mixed working fluid; fiber grating; calibration
