Abstract:
High-temperature strain gauges have garnered significant interest from researchers due to their high precision, exceptional temperature tolerance, and robust anti-interference capabilities. Furthermore, these sensors exhibit a strong linear relationship across a wide range of strain and temperature, making them widely applicable in various fields, including aerospace, the automotive industry, the metallurgical sector, and scientific research. This paper provides a comprehensive review of high-temperature strain gauges, focusing on three main technologies: SAW strain gauges, optical fiber grating strain gauges and TFSGs. We analyze the performance differences among various types of these sensors, systematically summarize several preparation techniques, analyze the performance testing methods for high-temperature gauges, and discuss their current application status and future development directions in related fields.
