FBGT series with quasi distributed optical fiber grating temperature sensor networking (hundreds of thousands of points), high temperature measurement accuracy (0.1 ° C ~ 0.5 ° C), wide range of temperature (100 ° C to + 300 ° C), no zero drift, is not subject to electromagnetic interference, corrosion resistance, resistance to shock vibration, long life and other advantages.Divided into surface type, embedded, immersion and so on a variety of packaging structure, can be widely used in Bridges, DAMS, oil pipelines, offshore oil platform and other large structures and buildings, medicine, chemical, electric power, military industry, aerospace, fire protection, mining and other large facilities or equipment in the field of distributed accurate temperature measurement.

Embedded optical fiber grating temperature sensor through internal sensing element, fiber Bragg grating signal center wavelength of light reflected by moving to detect temperature, temperature measurement precision and resolution is not affected by light source fluctuation and the influence of the bending loss of transmission lines, can be directly through the optical fiber signal remote transmission (over 40 km), monitoring the scene without power supply.Sensor has a surface type, embedded, immersion and so on a variety of packaging structure, can be widely used in Bridges, DAMS, oil tank, oil pipelines, tunnels, grain depot, the workshop, large structures such as offshore oil platform and architecture, medicine, chemical, electric power, military industry, aerospace, fire protection, mining and other large facilities or equipment in the field of distributed accurate temperature measurement.
