光纤传感干度测量仪研制

Development of Steam Quality Measurer Based on Fiber-optic Sensor

运用光纤传感技术研制的干度测量仪 ,通过水汽两相流在光学界面上不同折射率具有的不同反应 ,直接得出干度变化的响应值。从理论上分析了干度测量仪的工作原理 ,并实验证明可以连续、在线测量 ,可在高温。

The measurer of steam quality, based on fiber-optic sensor, can directly get the response value of the steam quality fluctuation, which works on the principle of refractive index modulation. The operation principle of the measuer is analyzed. Experiments show the measurer could realize the steam quality measurement on the spot continously under the conditions of high temperature, high pressure and narrow space.
