摘要

为测量液体的粘度

设计并研制了一种基于旋转式的高灵敏度且抗电磁干扰的光纤Bragg光栅（FBG）粘度仪。该粘度仪传感器部分由弹性空心圆柱体与定子相连接组成

光栅贴于弹性空心圆柱体内壁。经计算得

该粘度仪的灵敏度为80 pm/（Pa·s）。用蜂蜜和食用油进行实验

在旋转速度同为120 rad/min的条件下

测得的平均动力粘度分别为10.15 Pa·s与6.6 Pa·s。实验结果表明:旋转式FBG粘度仪的测量结果在合理范围以内。

Abstract

To measure viscosity of liquid

a kind of fiber Bragg grating（ FBG） viscometer based on rotary with high sensitivity and anti-interference is designed

researched and fabricated. The sensor of viscometer is made up of elastic hollow cylinder and stator

FBG is sticked in the inner wall of elastic hollow cylinder. By calculation

the sensitivity of viscometer is obtained

which is 80 pm /（ Pa·s）. Experiments with honey and cooking oil show that the average of viscosity is 10. 15 Pa · s

and 6. 6 Pa · s

when in the same rotation speed with 120 rad / min.Experimental results show that the measuring results of rotary FBG viscometer is within reasonable limits.
