Description
VW embedment strain gauge is embedded in the concrete structure to measure the effective strain that affect the concrete inside. This product can measure stress, distribution direction and trend of strain, etc. with the strain gauge in 2 – directions using the Rosette Block. Also, non 4 – stress strain gauge case can be used to compare and verify the non – stress condition with load applying condition in dam, bridge, subway structure, etc. which are required for long – term measurement by non – stress case.
