Simulation Research on the Potential and Sencitivity Distribution of ECT System Based on Finite Element

Abstract:

This paper firstly introduces the composition and mathematical description of the capacitance sensor, meanwhile, establishes the mathematical and finite element model of it. According to previous finite element model as mention above, this paper bases on FEM to compile the program and calculate the distribution of potential with shield and no shield. The program obtains result of the contour figuer of every node. Then comparing the potential value on nodes at the same place. In terms of previous analysis result, this essay amis to change electrode plate width and the length of radial shielding electrode by the order. In the meantime, it also research Potential value change in the same area and analyze the influence of potential distribution in those electrodes that were affected by the width of electrode and length of radial shielding electrode. In the end, this study obtains a lot of useful conclusions for the capacitance sensor design.
