SYSTEM FOR ELECTRICAL CAPACITANCE TOMOGRAPHY

摘要

The present invention provides an improved system for electrical capacitance tomography imaging of material located within a space delimited by walls. The system comprises multiple electrodes arranged on said walls and defining a capacitance between each pair of electrodes within said multiple electrodes; and a charge/discharge measuring circuit connected or connectable to each of said pairs of electrodes. The charge/discharge measuring circuit comprises switching means for alternately connecting an electrode as an excitation electrode and a measurement electrode. Signal lines connecting electrode surfaces of said electrodes to said charge/discharge measuring circuit are provided with shield lines and/or shield layers.
