摘要:
针对微型ECT传感器受限于应用场合,电极轴向长度过短的实用局限,提出采用电势测量方法.通过采集悬浮极片上的电势值进行图象重建.比较电势测量方法与传统的位移电流方法,发现在给定相同激励电压时,电势测量值仅取决于电容的比值而独立于电容本身值,在一定程度上降低了对电极轴向长度的要求.研究表明电势测量方法更加适合于微型ECT传感器.最后利用非线性GA-ECT技术从电势测量值给出了图象重建的结果.
Abstract:
The technology of electrical capacitance tomography(ECT)has great potential in industrial applications due to its non-intrusive, simple construction and low cost nature. In this paper, potential measurement method is suggested to miniature sensors for the very short axial length restricted by its application. Image reconstruction using the potential measurement method is based on the potentials on the floating electrodes. The potential measurement method is compared with the displacement current method. It is concluded that for a given excitation voltage, the potentials are dependant on the capacitances ratios only, independent from capacitance themselves. The requirement to electrode’s length is relaxed. It shows that the potential measuring method is more suitable to miniature ECT sensor. At last, an example of application of this method in non-linear GA-ECT provides satisfactory simulation results.
