The reflection wavelength of the metal FBG temp. sensor has a linear relationship with temperature, which is suitable for temporary or permanent monitoring and easy to form a distributed sensing network.
It is feasible for surface mounting, hanging, embedding, bolts and other fixing methods,
and widely used in high and low temperature, high voltage and high electromagnetic environment, such as substation, power cabinet, wind power generation,
hydraulic power generation, thermal power generation, underground mine and other projects for fire early warning.
