FINITE ELEMENT MODELLING ANALYSIS AND DESIGN OF THE PRIMARY SENSOR FOR ELECTRICAL CAPACITANCE TOMOGRAPHY

The CAD of the primary sensor subsystem for a 12-electrode electrical capacitance tomography（ECT） system is explored using the finite element method（FEM） ，and the image reconstruction is also studied．Results are presented in the form of sensor’s performance parameters as functions of its various geometric parameters．From the point of view of capacitance measurement and image reconstruction，a set of suitable design parameters is found．
