Vibrating Wire Interface Extensometer (Dislocation Meter)

BGK4420I vibrating wire interface extensometer (dislocation meter) is used to measure the displacement of the boundary of fills or structures, such as the staggered displacement of the joint between soil and bedrock, between soil and concrete, or between soil and other media. It is suitable for measuring dislocation and relative settlement between dikes, core walls, revetments, fills and foundation structure surfaces. The instrument is installed in the embedment type, and can be directly embedded in the monitoring point. In addition, the instrument can be embedded between concrete and bedrock to measure the dislocation displacement along the joint by adding flexible protection measures.
