20140123764 | Fiber Bragg Grating Pressure Sensor with Adjustable Sensitivity - A new type of optical pressure sensor with adjustable sensitivity is proposed based on the fiber Bragg grating (FBG). In this technique, the pressure changes the length of a metal bellows which is placed behind a spring. The fiber grating is fixed over the bellows between a fixed position and the connection point of bellows and spring. The wavelength change of FBG is caused by the change in the bellows length; however, the spring controls the total length expansion of the bellows. It will bring two benefits: first it is easy to change the pressure sensing range by changing the spring rate; and secondly the spring improves the linearity of the wavelength sift due to the pressure. The FBG is installed outside of the bellows and is not in contact with the material in which the pressure should be measured (gas or liquid) in contrast with other pressure sensors where the FBG is inside the bellows. This is an important issue because some materials could damage or change the characteristics of the fiber over the time. | 05-08-2014 |
