The Application of the Vibrating Wire Sensor and its Network Automatic Measuring Unit in the Monitoring System for Bridges

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.
