摘要：

Ultrasonic velocity measurements provide process related information to complement conventional temperature and pressure measurements, since velocity varies with material type and with temperature and pressure conditions. The technique is non-invasive, can be applied directly to the process, and results are available in real time. An ultrasonic virtual instrument has been used on industrial scale extruders in house. Experimental results are presented, showing ultrasonic velocity to be a powerful tool for improving knowledge of polymer melt bulk temperature during extrusion.
