GFJ Type Fiber Bragg Grating Seam GaugeDetailed product description：

The GFJ type fiber Bragg grating displacement sensor is used to measure the relative displacement between various structures, and can also be used for real-time monitoring of crack opening and closing. It is suitable for various tunnel segment joints, dam body displacement, soil settlement, rock, mountain, slope monitoring, etc. During installation, fix the sensor and probe on the moving object and reference object respectively.

The GFJ fiber Bragg grating seam gauge can be used for both long-term and short-term monitoring, and the sensor can be reused.
Fiber Bragg grating displacement sensors have the advantages of high accuracy, high sensitivity, and long lifespan, and can be combined with other types of fiber Bragg grating sensors to form an all-optical monitoring network.
