Abstract
Temperature is one of the concern parameters particularly in plastic injection process. This paper introduces the new application of Electrical Capacitance Tomography (ECT) as a non-intrusive, non-invasive technique in determining the temperature distribution on a polycarbonate material. The objective of this study is to tract the intensity of temperature as it's distributed during the phase change of polycarbonate resins. Polycarbonates have been placed inside the container with 12-electrodes circumferentially mounted onto it while the other ends of the electrodes are connected to ECT. The container was heated with a given period of time. The relative permittivity has been determined by ECT and out of it, temperature calculations were performed. The results of this work give emphasize the relationship of temperature and relative permittivity which was found inversely proportional to one another. ECT is suitable in measuring not only electrical properties of a certain material but also in determining temperature distribution.
