| 摘 要： | 为解决工业喷吹管道内气／固两相流固相浓度的在线实时测量问题，研制了一种带有对称边保护极板的螺旋形状面板电容式相度传感器，通过优化设计，其检测场空间内灵敏度均匀性误差优于５％，降低了相分布及流型变化对测量的影响，有效地减小了测量误差。已在现场应用，运行效果良好。

| Abstract: | A helical shaped surface plates capacitance transducer has been designed to solve the problem of in situ measurement of instantaneous solids phase concentration of gas/solid two phase flow. The homogeneous error of the sensitivity distribution in the sensing field is less than 5% by using optimum design,which diminishes the effect of phase distribution and flow regime changes on the measurement. The transducer has been used at the work site with good running result. |

| Keywords: | helical shaped surface plates capacitance transducer for phase concentration measurement homogeneous error flow regime. |
