Influence of shielding arrangement on ECT sensors Martínez Olmos, Antonio Alberdi Primicia, J. Fernández Marrón, J. L. Electrical capacitance tomography sensor Finite element method Shielding arrangement Standing capacitance Sensitivity map Sensing field Reconstructed image This paper presents a full 3D study of a shielded ECT sensor. The spatial resolution and effective sensing field are obtained by means of Finite Element Method based simulations and are the compared to a conventional sensor's characteristics. An effective improvement was found in the sensitivity in the pipe cross-section, resulting in enhanced quality of the reconstructed image. The sensing field along the axis of the sensor also presents better behaviour for a shielded sensor. 2014-07-22T08:40:17Z 2014-07-22T08:40:17Z 2006 info:eu-repo/semantics/article Martínez Olmos, A.; Alberdi Primicia, J.; Fernández Marrón, J.L.
