FBG Displacement Sensor

FBG Displacement Sensor 02 is a FBG technology based pull-rope displacement sensor, which is suitable for measuring the joint opening or boundary displacement between concrete blocks (such as the sinking tube of the segment meter), and can also test the change of the expansion joint at the beam end.

The product connects two components to be tested through a steel wire rope. When there is a relative displacement between the components, the steel wire rope is pulled out or retracted, and the displacement is converted into a stress on the internal fiber Bragg grating, thereby changing the wavelength output value of the FBG to achieve the purpose of testing. Built-in temperature FBG can be used for temperature measurement and temperature compensation for displacement gauge.
