差动式光纤储量检测系统的静态特性测试

The Static Characteristic Testing of Fiberoptic Differential Storage Measuring System

采用检测储罐底部和顶部压力差的方法，给出了一种自动补偿式光纤差动传感器构成的储量检测系统；建立了该检测系统的准静态输入输出线性回归方程；测试了系统的输入输出特性曲线、线性度和迟滞性；给出了该系统光源波动补偿特性和温度补偿特性的测试结果，并进行了系统的重复性和稳定性测试。

Using the method of testing the differential pressure between the bottom and the top of an oil storage tank, a fiber-optic differential storage measuring system is introduced in this paper, which can compensate the effect of light source fluctuation and the temperature variation automatically. The quasi-static input-output linear regression equation of the measuring system is established, and the testing results of input-output curve linearity and sluggishness are given. Finally, the compensation characteristic and the repeatability as well as the stability are also given.
