| 摘 要： | 阐述了一种带温度补偿、基于薄壁圆筒结构的高量程光纤光栅（FBG）压力传感器.薄壁圆筒直接作为弹性体,在压力作用下产生轴向位移来拉动压力敏感光纤以实现压力传感;通过被动温度补偿和残留温度效应主动实时修正来共同消除薄壁圆筒和压力敏感FBG的温度漂移;同时,对带温度补偿的FBG压力传感器的温度稳定性进行了讨论,给出了理想情况下该系统可达到的最优温度稳定性及决定因素.研究结果表明：基于30CrMiSiA材料管道结构的FBG压力传感器可以进行压力传感,其重复性为0.505 2%;回程误差为4.006%;线性度为0.285 5%;传感器精度为±2.639 8%;基于温度补偿进行温度去敏也有很好的效果,在-30～100℃范围内,该系统的温度稳定性因子为9.079 6%;随着实验温度范围减小至0～60℃,系统温度稳定性因子也减小至4.0%.

| Abstract: | A new style of fiber Bragg grating(FBG) pressure sensor based on a thin-walled cylinder structure with temperature compensation was described in this paper.The thin-walled cylinder,as an elastic element,converted fluid pressure into optical fiber strain directly.Passive temperature-compensating package and active correction for the residual temperature drift were adopted simultaneously to eliminate the thermal errors induced by the thin-walled cylinder and the sensing FBG.Besides,the temperature stability o... |
