geogage | V.W. Crackmeter

CONFIGURATION AND OPERATING PRINCIPLE

V.W. Crackmeter is designed to monitor displacement or crack by fixing the anchors in both sides of crack in concrete structures or rock.

Once a crack or displacement happens, it is delivered to the sensor through the anchors.

At this time, frequency of vibrating wire is changed and measured frequency can be converted into displacement with a gage factor.

PURPOSE

Monitoring size changes of crack in concrete structures or rock

Monitoring crack or movement by settlement, uplift

Monitoring crack condition of structure in seismic area

Monitoring progress of crack in decrepit tunnels or bridges

FEATURES

High stability and reliability in an extreme situation.

Excellent reproducibility and responsibility because not affected by the length of cable or resistance variation.

Easy coordination at construction field.

Easy installation.

Semi-permanent type and anti-rust material.
