摘要

电阻层析成像的电极与液体的直接接触可能导致电极腐蚀和极化，这限制了电阻层析成像在工业上的应用。基于石英晶体串联谐振原理，研制了电容耦合电阻层析成像系统(CCERT)。该系统可以在不接触液体的情况下测量电极间液体的电导率。开发了一个12电极的原型系统，并设计了其数据采集系统来实现电阻测量。为了测试系统的性能，进行了实验。实验结果表明，该方法可以重建管道内部的电导率分布图像。

Capacitively coupled electrical resistance tomography system based on quartz crystal series resonance

The direct contact between the electrodes of the electrical resistance tomography and liquid may result in electrode corrosion and polarization, which limits the application of ERT in industry. Based on quartz crystal series resonance principle, this paper develops a capacitively coupled electrical resistance tomography system (CCERT). This system can measure the conductivity of liquid between electrodes without contact with the liquid. A 12-electrodes prototype system is developed and its data acquisition system is designed to implement the resistance measurement. To test the system performance, the experiment is implemented. Experiment results show that the conductivity distribution images inside the pipe can be reconstructed.
