Abstract
Reliable and accurate pressure measurement is critical for a variety of applications where regulating flow, volume, and product quality are essential for ensuring safe operation. Traditionally, pressure is measured using gauges. While offering a cost-effect measurement solution, pressure gauges suffer from many limitations, such as frequent calibration needs, low tolerance in harsh environments, and the ability to only provide pressure at the discrete gauge location. To overcome the limitations of conventional pressure gauges, this study describes the development and demonstration of a quasi-distributed optical fiber-based distributed pressure sensor using fiber Bragg-gratings (FBGs) inscribed in a single fiber. The sensor assembly was experimentally demonstrated to show pressure-induced wavelength change that was quantified to successfully estimate pressure for different pressure conditions. The results are validated with finite element method-based numerical simulation.
