Fiber optic FBG sensors are capable of capturing data at multiple points along a large structure, measuring strain as small as 1µƐ up to more than 5000µƐ, temperatures up to 1000°C, near DC and high frequency vibrations as well as current, tilt, displacement and more…
A fiber can contain multiple sensing points called Fiber Bragg Gratings (FBG). Packaged FBG sensors can be daisy chained to simplify cabling.
An FBG fiber can directly measure temperature. 1°C will change the light reflected by the FBG by 10pm.
A packaged FBG fiber can translate strain into vibration and acceleration.
A packaged FBG fiber can very accurately measure tilt and displacement.
A packaged FBG fiber can measure current.
An FBG fiber can directly measure strain. 1 microstrain will change the light reflected by the FBG with 1pm.
Applying a special coating on the FBG fiber, it can measure H2 and humidity.
An FBG fiber attached to the circumference of a bearing or gearbox can measure load distribution and torque.
A packaged FBG fiber can measure pressure.
An interrogator is a type of data acquisition system. It sends light into the FBG fiber and captures the light reflected by the FBG sensing points in the fiber. The reflected light is then correlated to temperature, strain or other properties and converted to an electronic signal that can be send over a data network.
FBG sensors outperform in harsh environments
Fiber optic FBG sensors are ideally suited for demanding industries. After all, they outperform electric sensors in environments with lightning strikes, extreme temperatures, … or a combination thereof.
Extreme temperatures
do not damage or affect these sensors, making them ideal for applications in furnaces, chemical processes and cryogenic applications
Electromagnetic interference
has no effect on the light signal in the sensor so they can be used to monitor motors, generators, transformers and high-voltage switch gear
Corrosive environments
will not damage a sensing fiber as it is made of glass, making them ideal for use in off-shore applications and civil engineering
Lightning strikes
do not damage the sensor and the optical fiber cable will isolate your electronics from the sensor so your electronics.
Explosive environments
are no problem for these sensors are they use light signals rather than electric signals, so they are safer to use in oil & gas applications
