Abstract: This paper presents a full 3D study of a shielded ECT sensor. The spatialresolution and effective sensing field are obtained by means of Finite Element Methodbased simulations and are the compared to a conventional sensor's characteristics. Aneffective improvement was found in the sensitivity in the pipe cross-section, resulting inenhanced quality of the reconstructed image. The sensing field along the axis of the sensoralso presents better behaviour for a shielded sensor.
Keywords: Electrical Capacitance Tomography sensor; Finite Element Method; shielding arrangement; standing capacitance; sensitivity map; sensing field; reconstructed image
