Temperatures play a vital role in almost all industries. This paper introduces the applicability of Electrical Capacitance Tomography (ECT) as a new and non destructive technique in tracking the temperature distribution on a polycarbonate (PC) material for injection molding application. 20 ml polycarbonate resins have been placed inside the 30 ml. 12-Electrodes connected from the ECT are attached circumferentially inside the beaker to measure the capacitance of PC while the heat is continuously applied until the given time of 1Omin elapsed. The measured capacitance values pass through the ECT data acquisition system and fed into computer to display the inner process and by using a non-iterative algorithm; the cross-sectional image has been reconstructed. ECT is not only suitably excellent in measuring electrical parameters of a certain material but also in determining one of the thermodynamic parameters that contributes phase change such as temperature.
