Abstract

Abstract

There are many types and applications of resistance strain sensors, which are widely used in industries and fields such as bridges, tunnels, construction, aerospace, etc. They are often used to monitor their structures. Therefore, it is very important to evaluate the dynamic characteristics of resistance strain sensors reasonably. This article discusses and analyzes the characteristics of resistance strain sensors and the description of metrological characteristics in relevant domestic and foreign standards and specifications. In view of the current status of metrological calibration of resistance strain sensors, this paper discusses a method for calibrating the dynamic characteristics of resistance strain sensors using existing vibration measuring devices. This method is based on the existing vibration standard device, collecting vibration table signals and strain sensor signals through a dynamic signal analyzer, and analyzing the measurement signals to obtain dynamic sensitivity, completing the calibration of sensor dynamic characteristics. The feasibility and good repeatability of this method were verified through experiments. Finally, the data processing process was explained and the uncertainty of the dynamic sensitivity of the sensor was evaluated.
