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.

摘要

高温应变片因其高精度、卓越的温度耐受性和强大的抗干扰能力而受到研究人员的广泛关注。此外，这些传感器在很宽的应变和温度范围内呈现出很强的线性关系，使其在航空航天、汽车工业、冶金行业和科学研究等各个领域都有广泛应用。本文对高温应变片进行了全面综述，重点介绍了三种主要技术：声表面波应变片、光纤光栅应变片和薄膜应变片。我们分析了这些传感器不同类型之间的性能差异，系统总结了几种制备技术，分析了高温应变片的性能测试方法，并讨论了它们在相关领域的当前应用状况和未来发展方向。
