Function of Fiber Bragg Grating Differential Pressure Sensor

A fiber Bragg grating (FBG) flow sensor is designed and fabricated, in which two FBGs are fixed on the front and other side of the metal diaphragm, and differential pressure is used to monitor the flow rate of fluid. This review provides a comprehensive overview of FBG sensor technology. In order to accurate measurement of seepage water pressure in soil, according to the pressure sensor characteristic of bellows, and the strain sensor characteristic of triangle cantilever beam and FBG, a differential fiber Bragg grating sensor is designed. The temperature sensitivity of these two FBGs is 0. Their unique attributes—compactness, immunity to electromagnetic interference, and multiplexing capabi...
