The vibrating wire displacement meter is suitable for long-term measurement of the opening and closing degree (deformation) of expansion joints of hydraulic structures or other concrete structures, and can also be used to measure the displacement, subsidence, strain and slip of structures such as earth dams, earth embankments and slopes, and can simultaneously measure the temperature of buried points.
