Fiber Bragg grating sensors do not require electricity
Unlike electronic sensors, FBG sensors are passive, requiring no electrical power at the sensing point. Their construction within an optical fiber makes them small and lightweight, suitable for many monitoring tasks. They are easy to install, immune to electromagnetic interferences and can also be used in highly explosive atmospheres. But just how does a fiber Bragg grating work? Our experts answer this and other questions. In the electrical power industry (EPI) we have two facts that can cause collapse of an electronic sensor: presence of high voltage and presence of high electromagnetic interference. Therefore, depending on where we want to measure a parameter it can be very difficult or even impossible to use a. Fiber Bragg grating (FBG) sensors have emerged as advanced tools for monitoring a wide range of physical parameters in various fields, including structural health, aerospace, biochemical, and environmental applications. on different points on the same sensor cable.
