Fiber Optic Grating for Measuring Cable Temperature
A Fiber Bragg Grating (FBG) sensor is an optical device inscribed in a fiber using a UV laser pattern. Acting as a wavelength-selective mirror, it reflects a specific wavelength that shifts in response to strain or temperature changes. The other end of the fiber is attached to a light source. The light source is used to excite the Fluorescent material. After excitation, the Fluorescent material tends to. Highly Accurate Multi-point Bragg Wavelength Shift Detection system suitable for Temperature, Strain, and Vibration sensing in wide-range of Industrial, Commercial, and R&D applications using Fiber Bragg Grating Technology. Optimized for industrial and harsh environments, our FBG sensors can be photo-imprinted on fibers with acrylate, polyimide, or metallic. A fiber bragg grating temperature sensor is a type of sensor that uses a fiber bragg grating (FBG) as a sensitive component and is combined with a fiber bragg grating demodulator (FBG analyzer) to detect and monitor the temperature of the measured object and its environment.
