What Is a Displacement Meter?

VWD vibrating wire type displacement meter is suitable for long-term measurement of the opening and closing (deformation) of expansion joints of hydraulic structures or other concrete structures. , Slip, and can simultaneously measure the temperature of the buried point.

Displacement meter

The displacement meter is a sensor suitable for monitoring the shear displacement at the interface between the dam body and the bank slope or a relatively large relative displacement inside the dam body.

Used for long-term measurement of the opening and closing (deformation) of expansion joints of hydraulic structures or other concrete structures. It can also be used to measure the displacement, subsidence, strain and slip of structures such as earth dams, embankments, slopes, etc. Measure the temperature at the buried point. Equipped with accessories can be used to form deformation measuring instruments such as bedrock displacement meters, multi-point displacement meters, and soil strain gauges.
