Crack Displacement Transducers KG-B

KG-B Crack Displacement Transducer　
X:-2 to +4 mm　Y:±3 mmCE

The KG-B crack displacement transducer is used to measure the displacement in two directions simultaneously: the displacement of openings, such as concrete cracks or joints, and the horizontal shear displacement. It is mounted on a structure by bonding with adhesive. Because the fixing jigs are detachable, the transducer can be demounted and set on a different structure. This allows this transducer to be used repeatedly on different structures. In addition, the small-size feature makes this transducer suitable for indoor measurement.
