| 中文摘要: |
| 基于工业流体流量测量技术、光纤布拉格光栅(fiber Bragg grating,FBG)传感检测技术与靶式流量计原理,针对单个光纤Bragg光栅传感系统对温度交叉敏感的问题,设计并且制作了一种基于双光纤Bragg光栅流量传感器。该传感器采用靶盘结构作为光纤Bragg光栅流量传感器的受力元件,对温度起到了补偿作用,并且有效地提高了应变测量灵敏度。实验表明,该流量传感器的线性误差为0.31%。 |

| Based on industrial fluid flow measurement technology,fiber Bragg grating(FBG) sensing technology and target type flowmeter for overcoming a single fiber Bragg grating sensing system for temperature sensitive issue cross,we design and produce a fiber Bragg grating based on dual-fiber Bragg grating sensor flow control.The sensor uses the target disk structure as force element for temperature compensation,and effectively improves the strain measurement sensitivity.Experimental results show that the flow sensor linearity error is 0.31%. |
