distributed fiber optic temperature sensor Long measurement distance

After more than ten years of development, distributed fiber optic temperature measurement devices have been widely used in fields that require temperature measurement, fire alarm, and energy conservation and emission reduction, such as power cable tunnels, comprehensive pipe galleries, coal industry, and data centers, due to their advantages of long measurement distance, usahihi wa juu, no measurement blind spots, and strong resistance to electromagnetic interference.

The distributed fiber optic temperature measurement device is made using the spontaneous Raman scattering effect. Its anti Stokes signal is temperature sensitive, while the Stokes signal is temperature insensitive. The temperature values at each point along the fiber optic can be calculated using its ratio of light intensity, and precise positioning can be achieved using its Rayleigh scattering technology. Basi, its spatial resolution and temperature measurement accuracy are important characterization parameters.
