Embedded FBG temperature compensation strain sensor EST-01 is mainly used for internal strain measurement of concrete, reinforced concrete or plastic materials such as foundations, pile foundations, bridges, tunnels, linings, etc, so as to facilitate long-term observation of structural stress and strain changes and state analysis. The sensor has a built-in temperature compensated FBG, adopts a unique elastic beam structure, and has high measurement resolution and measurement accuracy. The signal can be transmitted over long distances through optical fibers.
