Abstract

In this paper is proved the flexibility of LabVIEW (Laboratory Virtual Instrumentation Engineering Workbench) - graphical programming software – when it is used in connection with applications of ultrasound measurements in the field of plastic materials characterization. The ultrasonic measurement was carried out on plastic specimens with immersion method. In the first step the measurement was made in water with a transducer that generates a longitudinal 5 MHz wave. The same measurement was repeated in a magnetic fluid, water diluted. All of the measurements are oriented to obtain necessary data for the FP7- W2P Plastics project development. In Transylvania University laboratory, the measurement setup used was the EPOCH XT device from PARAMETRICS-NDT. The data can be saved on PC like normal TXT files and exported in Excel and LabVIEW. A preliminary application was developed to see the imported data in one Wave Form Graphic (WFG) or XY graph in LabVIEW. This data can be used easy now in idea of needs for future calculus and data computation. The obtained data will be used for the separation process of the polymeric waste immersed in a magnetic fluid..
