High Temperature Resistant Fiber Optic Installation Method

1. High-temperature resistant optical fiber reflective bending radius must be more than 25MM!
2. Note: The bending radius cannot exceed the limited requirements, otherwise the fiber will be damaged.
3. This fiber optic sensor needs to be used with a fiber optic amplifier.

Applications

Tips: What is the working principle of high temperature fiber optic sensors?

High temperature fiber optic sensors use optical fibers as sensing elements to measure temperature through the transmission and modulation of optical signals. Fiber optics exhibit excellent stability in high temperature environments, and temperature changes are typically detected through fiber Bragg gratings (FBGs), interferometric techniques, or fluorescence attenuation. For example, FBG sensors utilize the property that the Bragg wavelength of a grating in an optical fiber shifts with temperature to achieve highly accurate measurements. This passive sensing technology is resistant to electromagnetic interference, high temperature and corrosion, and is suitable for temperature monitoring in extreme environments.
