This series of vibrating wire strain gauges are designed to measure large strains up to 5000 micro-strains. The embedment strain gauge is used to measure strains in concrete mass. It is designed to measure strain in underground cavities, tunnels, buildings, concrete and masonry dams etc.
The embedment strain gauge has stainless steel flanges at either ends and is suitable for embedment directly in concrete. Any deformation in the concrete mass causes the two end blocks to move relative to one another, thus changing the tension in the wire, resulting in a corresponding change in its frequency of vibrations. It is similar to the embedment strain gauge, except that it is used to measure large strains up to 5000 micro-strains. other models only measure up to 3000 micro-strains.
