Description
Embedded FBG strain sensor ES-01&EST-01 is specially used for the internal strain measurement of concrete, reinforced concrete or plastic materials, so as to observe the change of internal stress of the structure for a long time, conduct state analysis, and achieve the purpose of warning and object health status diagnosis. The sensor is small in size and easy to install. It is connected in series or in parallel, and it is easy to form a quasi-distributed sensor network.
