Abstract

Electrical capacitance tomography (ECT) is a non-invasive monitoring technology, and traditional ECT systems typically adopt 8-16 fixed electrode plates. This study presents a dual-electrode rotating ECT system controlled by a hollow torque servo motor using the field-oriented control algorithm, thereby replacing traditional multi-electrode plate switching with dual-electrode rotation. The influence of different electrode rotation angles on imaging is investigated, and the image reconstruction performance of the linear back-projection and Tikhonov regularization algorithms is compared. Experimental results showed that the system can stably achieve a capacitance resolution of 100 aF (0.1 fF) and that imaging in the equivalent four-electrode and eight-electrode modes accurately identifies typical flow patterns in pipelines. The experimental results demonstrate the feasibility of image reconstruction using the dual-electrode rotating ECT system, paving the way for the industrial adoption of ECT technology.
