Electrical Capacitance Tomography System For Industrial Applications
An electrical capacitance tomography system (ECT) has been developed. The system consists of a circular sensor with 8 electrodes. A charge generator injects charges into the sensor filled with objects different dielectric constants. The charges, in the form of potential dropped, on another electrode are measured and acquired digitally to a PC for calculating the capacitance and estimating the d...
متن کاملApplication Research of Wavelet Fusion Algorithm in Electrical Capacitance Tomography
Electrical capacitance tomography (ECT) technology has the softfield nature and the ill-posed problems. To solve the problem of low imaging quality by standard Tikhonov regularization, a wavelet fusion algorithm based on Tikhonov regularization is proposed in this paper. Firstly, Tikhonov regularization method is used to solve ill-posed characteristic of system inverse problem, then the initial...
متن کاملElectrical Capacitance Tomography System
Electrical Capacitance Tomography is a non intruding technique used in industries. It is based on measuring the capacitance of multi-electrode ECT sensor produced by the change in dielectricity or due to change in concentration of material. With the use of computed values, a cross sectional image of the material placed in the dielectric medium is obtained. ECT system can be used in chemical fie...
متن کاملVirtual Instrument for Online Electrical Capacitance Tomography
Electrical capacitance tomography (ECT) is a technique invented in the 1980’s to determine material distribution in the interior of an enclosed environment by means of external capacitance measurements (Huang et al., 1989a, 1992b). In a typical ECT system, 8 to 16 electrodes (Yang, 2010) are symmetrically mounted inside or outside a cylindrical container, as illustrated in Figure 1. During the ...
متن کاملNon Iterative Inversion Method for Electrical Resistance, Capacitance and Inductance Tomography for Two Phase Materials
This paper focuses on the application of a recently proposed non-iterative inversion method for three different imaging techniques for two phases materials. Specifically, two techniques concern the retrieval of the resistivity of a conductor (electrical resistance tomography and magnetic induction tomography) and one technique concerns the retrieval of the permittivity of a dielectric material ...
