Principle preparation and performance characterization of sensors (IMAGE)
Caption
This study proposes a high-temperature thin film thermocouple temperature sensor based on YSZ (Yttrium Oxide Stabilized Zirconia) material doping. The material performance is improved by doping an appropriate proportion of YSZ in In2O3. The thermocouple is designed based on the temperature measurement principle, first principles, and simulation of the thermocouple, and prepared through screen printing technology. The test results show that its maximum working temperature is 1850 ℃, and its performance indicators, especially the temperature measurement upper limit, are at the leading level in current research on thin film thermocouples. In order to improve the repeatability of thin film thermocouples without changing their thermoelectric output, this study compensates for the repeatability error through the CNN-LSTM Attention neural network.
