Abstract High-temperature thin-film thermocouples (TFTCs) have attracted significant attention in the aerospace and steel metallurgy industry. However, previous studies on TFTCs primarily focused two-dimensional planar-type, whose thermal sensitive area has to be perpendicular test environment, therefore affects fluids pattern or loses accuracy. In order address this problem, recent developed three-dimensional probe-type TFTCs, which can set parallel environment. Nevertheless, are limited by...
