一、前言测量混凝土建筑物内部应变的传感器,不但要有较高的灵敏度和测量精度,还要求传感器具有良好的防水和长期稳定工作的性能,并且能够进行长距离遥测。七十年代初,日本共和电业研制成功一套贴片式仪器,以电阻片作为敏感部件的,其灵敏度高,适用范围广,并能实现遥测自动化。但该仪器不能测量温度,长期稳定性能如何,也还不清楚。 I. INTRODUCTION Transducers that measure the internal strain of a concrete building not only have high sensitivity and measurement accuracy, but also require the sensor to have good waterproof and long-term stable performance and be capable of long-distance telemetry. The early seventies, Japan’s Republican electric power industry successfully developed a patch-type instrument to the resistive sheet as a sensitive component, its high sensitivity, wide range of applications, and can achieve telemetry automation. But the instrument can not measure the temperature, the long-term stability of how, it is still not clear.
