Metal fiber grating strain sensor BG-FBGS-SM

The metal fiber Bragg grating strain sensor is not affected by electromagnetic interference, naturally explosion-proof and has good dynamic characteristics. Long-term stable zero point and minimal temperature drift; The feature of being easy to form a distributed sensor network; All stainless steel material encapsulation, fully sealed inside; Easy to install and reusable; Optical fiber dual-end outlet, can be measured in series; Built-in temperature compensation sensor, no need for external temperature sensor; The external dimensions and installation base can be customized according to the user's requirements. It is installed by embedding and surface bonding. It is applicable to the internal strain measurement of materials such as concrete, reinforced concrete or steel structures, so as to observe the changes in structural strain over a long period of time. It is mainly used for structural health monitoring in civil engineering, oil and gas pipelines, and offshore oil platforms. And the transportation industry is suitable for the buried type.
