Embodiment Construction
[0035] Please refer to figure 1 , a vibrating wire sensor of the present invention, including a shaft sleeve 10 and a steel string 20 placed in the shaft sleeve, the two ends of the steel string 20 are fixed in the shaft sleeve 10, and also include a The pressing piece 30 on the steel string 20 can move axially in the sleeve 10 so that the contact point between the pressing piece 30 and the steel string 20 can be adjusted. The pressing part 30 presses the different positions of the steel string 20, which can change the force, shape and aspect ratio of the steel string 20, so that the vibration frequency of the steel string 20 can be adjusted. Therefore, the vibrating wire sensor can be in the same tension state Next, the vibration frequency of the steel string 20 is adjusted to a fixed value.
[0036] It also includes an elastic member 80 arranged in the shaft sleeve 10 and exerting elastic force on the steel string 20 to tension the steel string. The degree of tightness of t...
