Computer Control and Data Processing in Extrusion Rheometers

Abstract

In this chapter we shall not concern ourselves with the detailed architecture of microprocessor systems, but rather with the use of modern computer technology to enhance the efficiency and effectiveness of extrusion rheometers. We shall not deal in depth with those modern extrusion rheometers which are fully instrumented, since they are described elsewhere in this volume. However, users of these instruments may find our observations to be of value in sifting genuine material flow data from instrumental artifacts. We shall attempt to lead those unfamiliar with the field to apply modern instrumentation techniques to their extrusion rheometers. Throughout, an eye will be kept on cost, as the most expensive system is not necessarily the most cost—effective.
