چکیده
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 field, industrial field and pharmaceutical and oil industry and for homeland security. In the paper presented here, operation principles and calibration methods of ECT system is discussed. The system is calibrated under certain conditions to find the relation between values indicated by measuring instrument or system or values represented by a materialised measure or reference material and values realised by measurement standards. KeywordsECT sensor, multi-electrode, dielectricity,

متن کاملAn 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...
