A low-cost intensity-based polymer optical fiber (POF) sensor for fuel level measurements in paramotoring and powered paragliding is presented, exploiting the advantages of the optical fiber sensing technology. Experimental results demonstrate that the best option can be performed by stripping the fiber at the desired discrete points to measure the fuel level as well as with a gauge-shape fiber bending. The prototype has a good linearity, better than 4% full scale (F.S.), and sensitivity around 0.5 V per bend are obtained. Hysteresis due to residual fluid at the sensing points is found to be less than 9% F.S.
本文提出了一种低成本的基于强度的聚合物光纤（POF）传感器，用于动力滑翔伞和动力滑翔伞的燃料液位测量，利用光纤传感技术的优势。实验结果表明，最好的选择是在所需的离散点剥去光纤，以测量燃料液位，以及使用仪表形状的光纤弯曲。该原型具有良好的线性度，优于 4%满量程（F.S.），并且每弯曲获得约 0.5 V 的灵敏度。在传感点处由于残留流体引起的滞后被发现小于 9% F.S.
