摘　　要：振弦式传感器基于钢弦频率随钢丝张力变化的原理而工作,具有分辨力高、抗干扰能力强、测值可靠和稳定性好,体积小等特点。是一种非常有发展前景的土工观测传感器类型。本文在阐述该传感器的工作原理基础上,详细介绍了FWC2000型振弦式网络测量系统及其测试原理,以及在桥梁安全监测中的应用情况。The vibrating wire sensor works on its vibrating frequency functioning with the tension on it. For the advantages of high-resolution, high -reliability, high-stability , good ant-jamming performance, small size and adjustable measuring value ,it is a potential type of earthwork sensor . On the basis of its principle, a high performance automaticinstrument for the vibrating sensor named FWC2000 is described in detail, and its application example in the monitoring system for the bridge security are briefly presented in the end.
