KD120 Composite strain gage
DESCRIPTION
The laying composite strain gauge KD120, hereinafter the strain gauge, is designed to measure deformations in reinforced concrete structures with the help of an embedded strain-gauge divider. The strain gauge, is a rod of composite reinforcement, equipped with a strain-resistive voltage divider and cable, is laid when concreting the structures. A composite deformation sensor built into the concrete makes it possible to carry out correct measurements of deformations in the body of concrete, in contrast to other solutions that strongly distort the stress fields, as a result which they can’t correctly set the boundary values. The calculation of cable resistance is made in accordance with the specification for cable KMPV 4х0.35.
