摘要
提出了一种基于嵌入式光纤光栅和碳纤维等强度梁的倾斜传感器。介绍了传感器的测量原理和制作方法,进行了全面的测试。研究结果表明,传感器在±30°量程内的倾斜测量灵敏度达到49.73pm/(°),精度可达0.101°,测量重复性误差仅为0.62%,测量函数的线性拟合度达到0.99992,且抗蠕变和温度补偿能力良好,能满足复杂的电力环境下开展长期倾斜监测的要求。
A new inclination sensor based on embedded fiber gratings and carbon fiber equi-strength beams is proposed.The measuring principle and the manufacture methods of this sensor are first introduced.Then this sensor is fully tested.The research results show that,within a measurement range of±30°,the sensor possesses a sensitivity of 49.73 pm/(°),a measurement accuracy of 0.101°,a repeatability error of 0.62%,and a fitting linear correlation coefficient of 0.99992.Furthermore,the creep resistance and the good temperature compensating abilities are good.The requirement of long-term inclination monitoring under complex electric environments is met.
