Dual-End Ceramic FBG Temperature Sensor

The dual-end ceramic FBG temperature sensor is a professional temperature measurement device based on Fibre Bragg Grating (FBG) technology, housed in high-density alumina ceramic encapsulation. It is designed for high-precision, high-reliability industrial monitoring applications. The sensor relies on the optical properties of the FBG, which forms a periodic refractive index modulation structure through UV lithography. When the temperature changes, the difference in thermal expansion between the ceramic package and the optical fibre, combined with the thermo-optic effect of the fibre, causes a stable shift in the central wavelength of the reflected light. By analysing this wavelength shift with a compatible FBG interrogator, the sensor achieves temperature measurement accuracy of ±0.5 °C, while also providing strain-related parameters.
