Optic fiber Bragg Grating sensor for temperature measurement provide many advantages over conventional electrical systems, particularly in applications that are exposed to harsh environments and require long-range, long-term deployments.
Bragg grating sensor is a perfect option for a variety of applications. These sensors are insensitive to the environmental changes and passive, which is a big upgrade compared to the regular electrical ones. They have higher accuracy and resolution, and they are immune to electric sparks. Long reliability period, ability to resist corrosion and other harsh environments are packed in a very compact size device.
One of the biggest advantages of FBG temperature sensor is the fact that its fiber optic temperature measurements are absolute, and it has the fastest response compared to other options. The highest return speed is perfect in the cases where temperature changes are fast and extreme.
Fiber optic temperature sensors are a perfect solution for difficult-to-reach locations and massive sensing networks. You can also use FBG temperature sensors for thermal compensation of any other FBG sensors
