Abstract: The principle of electrical capacitance tomography (ECT) is introduced and the simulation based on the finite element method (FEM) about the sensitivity distribution of capacitance transducers is discussed. The influence which the structural parameters of transducers impose on the performance of ECT is studied. The optimum design of transducer is achieve to improve the performance of transducer based on the given optimum function by the methods of finite element and orthogonal test design, which offers reference for the design and development of transducers.
