| Abstract: | The monitoring of bridge cable stress during stretching with vibration string pressure sensor is systematically introduced from working principle, structural characteristics as well as technical indexes of vibrating wire transducer. The research on actual project shows that there is difference between numbers read from vibration string pressure sensor and stretching jack, and the one from vibrating wire transducer is reliable. |
