An Improved Normalisation Approach for Electrical Capacitance Tomography
An electrical capacitance tomography (ECT) system is calibrated at the upper and lower values of permittivity. The measured capacitances are usually normalised and then used for image reconstruction. The conventional normalisation approach assumes that the distribution of the materials is in parallel and hence the normalised capacitance is a linear function of the measured capacitance. This app...
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 کاملDesign of an Electrical Capacitance Tomography System based on LabVIEW
Electrical capacitance tomography (ECT) is an effective technique for visualizing the distribution of dielectric materials inside a closed pipe or vessel. The design of an ECT system based on LabVIEW is described in this paper. The system can be divided into three parts: sensor system, data acquisition system, and imaging computer. The data acquisition system designed takes C8051F700 MCU as the...
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 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 (...
