Abstract
The optical fiber sensing technology has been rapidly applied in manufacturing and industrial fields. In this paper, a diaphragm-type fiber Bragg grating (FBG) sensor used for detecting the static/dynamic pressure of gas or liquid, is designed and experimentally studied. The pressure sensitivity of the sensor is obtained from both analytical solution and simulation calculation using finite element analysis (FEA). The Experiment results indicate that the pressure sensitivity of the sensor is -3.21 pm/kPa in a range from 0 to 500 kPa, and the linear correlative coefficient reaches 99.98%. This kind of pressure sensor could be widely used for pressure's quasi-distributed measurement and long-term on-line monitoring at a remote distance.
