Fiber Bragg grating for air pressure measurement
Fiber Bragg grating (FBG) pressure sensors have the potential to replace conventional voltage sensors due to their compact size, resistance to electromagnetic interference, excellent safety, distributed sensing, and numerous other intrinsic benefits. It is frequently employed in the domains of. This paper presents the development and evaluation of four sensors based on multiple fiber Bragg grating (FBG) constellations embedded in a silicon dioxide single-mode fiber (SMF) for simultaneous measurement of pressure, temperature, and bending curvature. They are easy to install, immune to electromagnetic interferences and can also be used in highly explosive atmospheres. The bending strain of a circular diaphragm induced by uniform pressure was transferred to the FBG sensor.
