In this study, a high-precision counterweight self-calibrating surface thermometer is designed to reduce human and environmental influences on thermocouple during measuring. A self-weighted spring structure based copper substrate ensure perfect contact between the temperature source. conjunction, wind guard coupled with insulating materials optimize thermal exchange of thermometer. Subsequently, maximum error reduced ±1.5 °C by system hardware optimization. However, calibration alone insufficient. Furthermore, back propagation neural network employed calibrate Temperature sensor data are collected under various source temperatures airflow velocities train network. Hence, effectiveness proposed Gaussian function in enhancing measurement accuracy demonstrated. The results show higher stability repeatability than thermocouple-based thermometers. exhibits robustness against operational variability indication -0.2 °C. contrast, -2.8 -6.8 Regarding repeatability, standard deviation device 0.2%, highlighting its consistency performance.

High-temperature thin-film thermocouples (TFTCs) have gained significant attention in the aerospace and energy industries due to their compact size millisecond response time. Although previous studies reduced of TFTCs millimeter scale, heat flow field has continued limit temperature measurement accuracy. To address this issue, study used an electrohydrodynamic printing process fabricate tungsten-rhenium with a thickness at micrometer scale. In static test, showed good performance accuracy better than 1.2%, repeatability 0.99%, drift rate 0.72%/h. dynamic tests, time was 1.2 ms. Additionally, during flame gun heating exceeded those standard thermocouple.

In the aerospace industry, there is significant interest in high-temperature thin/thick film strain gauges (TFSGs) that possess hot-end component health monitoring capabilities. However, 3-D printed TFSGs exhibit limited thermal stability, and use of conventional thick-film encapsulation can significantly compromise gauge factor (GF). Here, we deposited a sensitive layer using printing then protective magnetron sputtering to complete preparation AgPd TFSG. Experimental confirmation showed as thickness increases, GF TFSG decreases. The at room temperature was 1.327 with decay rate only 1.4% when magnetron-sputtered yttria-stabilized zirconia (YSZ) $2 ~\mu \text{m}$ . test results had excellent repeatability wide range 100 °C–800 °C, coefficient resistance (TCR) 181 ppm/°C. addition, drift unencapsulated 0.29%/h for 8 h 800 0.04%/h YSZ layer. For measurement, exhibited low mechanical hysteresis, elevated temperatures within notation="LaTeX">$\pm 500 \varepsilon $ obtained not cyclic stability (3300 cycles) but also an ultrafast response (384 ms). This new methodology presents attractive route prepare high attenuation situ sensing components.
