Dual-End Ceramic FBG Temperature Sensor

The dual ended ceramic FBG temperature sensor adopts high-density alumina ceramic packaging and is based on fiber Bragg grating technology. Through the difference in thermal expansion between ceramics and optical fibers and the thermal optical effect, the reflected light center wavelength is stably shifted. Combined with FBG interrogator, it achieves a temperature measurement accuracy of ± 0.5 ° C and also measures strain parameters.
