摘　　要：振弦式传感器是基于钢弦频率随钢丝张力变化的原理而工作的 .具有结构简单、分辨力高、抗干扰能力强、测值可靠、体积小等优点 ,是一种非常有发展前景的安全监测仪器 .本文在阐述振弦式传感器的工作原理基础上 ,详细介绍了本公司生产的 FWC2 0 0 0型振弦式网络测量系统及其测量原理 ,此外 ,还就该测量系统在桥梁。The vibrating wire sensor works on its vibrating frequency functioning with the tension on it. For the advantages of high resolve, high reliability, high stability and good anti jamming performance, it is a potential type of earthwork sensor which can be widely used in the monitoring systems for security. On the basis of its principle, a high performance automatic monitoring system for the vibrating wire sensor named FWC2000( one of our company′s products) is described in detail. Some application results of FWC 2000 are briefly presented in the end.
