Intelligent Tomography System (Electrical Capacitance Tomography)

Electrical Capacitance Tomography (ECT) is an intelligent tomography system that is
used as a monitoring system for the industrial process. It is important to monitor
specific process in industry so that we can get valuable information that may be used
for visualization, monitoring, mathematical model verification and intelligent control
of the process under investigation. ECT has several advantages over other
tomography techniques in process industry such as low-cost, rapid response,
portability, non-invasive and robustness. ECT capacitance sensor is made up of 8
electrodes that are arranged around a vessel. In order to obtain voltage measurements
between electrode pairs for all 8 electrodes around the vessel, data acquisition system
(DAS) is used to take the measurements simultaneously. These measurements are
recorded in the computer program which is HyperTerminal. Image reconstruction of
materials distribution in the vessel can be obtained by using the measurement values
that can be developed in MATLAB. However, this project only covers a part of ECT
which is DAS and capacitance sensor of ECT.
