Electrical 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 کاملElectrical Capacitance Tomography with a Square Sensor
Abstract – In the past, electrical capacitance tomography (ECT) with circular sensors has been extensively investigated. For some industrial applications such as circulating fluidised beds, square sensors are required. Research into this specific area has been carried out at UMIST for the first time. To generate sensitivity maps, the Laplace equation is solved using a finite difference method (...
متن کاملElectrical 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 کاملElectrical Capacitance Volume Tomography: Design and Applications
This article reports recent advances and progress in the field of electrical capacitance volume tomography (ECVT). ECVT, developed from the two-dimensional electrical capacitance tomography (ECT), is a promising non-intrusive imaging technology that can provide real-time three-dimensional images of the sensing domain. Images are reconstructed from capacitance measurements acquired by electrodes...
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 ...
