[0002] The vibrating wire type displacement meter is suitable for long-term measurement of the opening degree (deformation) of expansion joints of hydraulic structures or other concrete structures, and can also be used for measurement of displacement, subsidence, strain and sliding of structures such as earth dams, embankments and slopes, and can also be used for synchronous measurement of the temperature of buried points. When equipped with supporting accessories, the vibrating wire type displacement meter can be used as a sensor for measuring deformation such as a bedrock displacement meter, a multi-point displacement meter and a soil strain meter. The vibrating wire type displacement meter has an automatic temperature compensation function, and the temperature correction coefficient is very small after testing, so that temperature correction is not required during use. The vibrating wire type displacement meter has an intelligent identification function.
