Abstract


The electrical capacitance tomography (ECT) is a method to determine the material distribution within the interior of a closed object by measuring the capacitance value across externally mounted electrodes. This paper investigates the electrical capacitance tomography measure up to performance of triangle wave (AC) and charge-discharge (DC) methods. AC-DC based method applying voltage to the ECT sensor with different time. An excitation signal is applied to a pair of electrodes that forms a capacitor during each measurement step in order to determine the capacitance from the output current measured. When the voltages is applied to the pair of electrodes, the analyzing charging and discharging time and quality of the output signal. The betterment of the ECT system need to avoid stray capacitance then increase speed to switching combinational electrodes. This paper presents finally, the output voltages are also convert into images by using MAT Lab.
