FBG-D displacement sensor
The FBG-D displacement sensor uses fiber Bragg grating as the displacement sensitive element, and the measurement accuracy is not affected by the transmission distance of the fiber and electromagnetic interference. When the connecting rod is pulled out from the sensor body, it will cause a change in the wavelength of the grating. By reading the wavelength, the displacement of the measured object can be accurately obtained.
