本发明公开一种电容/图像法同体积场成像传感器,包括电容层析传感器和测量管道,电容层析传感器包括屏蔽罩和设置在测量管外的测量电极,测量电极沿轴向两端设有端屏蔽,端屏蔽、测量电极和屏蔽罩是多孔网状结构,测量管道采用透光的玻璃材料。与现有技术相比,本发明通过光透传感器引入同测量域光学图像“硬场”信息,可增加测量信息量,实现同体积场测量,通过轴向、横断面信息互补、修正,提高检测精度,拓展测量范围,对稀相密相均可成像。
The invention discloses a capacitance / image method homogeneous volume field imaging sensor, which comprises a capacitance tomography sensor and a measurement pipeline. The capacitance tomography sensor comprises a shielding cover and a measurement electrode arranged outside the measurement tube. The measurement electrodes are provided at both ends in the axial direction The end shield, end shield, measuring electrode and shield are porous mesh structures and the measuring tube is made of a light-transmitting glass material. Compared with the prior art, the invention can introduce the information of the “hard field” into the same measurement domain through the light transmissive sensor, increase the amount of measurement information, realize the measurement of the same volume field, complement each other through the axial and cross-sectional information, Improve the detection accuracy, expand the measurement range, the thin phase can be dense phase imaging.
