| 摘 要： | 文中提出了一种新颖的光纤布拉格光栅压力传感器,它是利用光纤布拉格光栅(FBG)对应变的传感特性,将光纤布拉格光栅粘贴于C型压力弹簧管上的特定位置,通过光纤布拉格光栅反射波长的变化,来实现对压力的测量。该传感器灵敏度的实验值和理论值分别为0.671nm/MPa和0.791nm/MPa,且具有很好的线性度,迟滞很小,有一定的发展前景。

| Abstract: | This paper presents a new type of Fiber Bragg grating pressure sensor on theoretic basis. Thanks to its strain sensing characteristics, FBG is pasted to the C-pressure elastic tube in a specific location, and pressure is measured according to the changes of FBG reflected wavelength. The experimental and theoretical values of the sensor sensitivity are respectively 0.671 and 0.791. The good linearity and small hysteresis of this type of sensor displays high potential for further development. |
