Continuous Rheometry: A New Process for On-Line Measurements and Control for Laboratory and Industry

  • André Kepes


Tremendous progresses were accomplished in experimental rheometry in the past 10 years, involving electronics, microprocessors, digitalization, solid-state memory and computerizing. It is therefore extremely unfortunate, that no progress at all was made in the field of mechanics and instrument geometry: end effects, gap setting and calibration errors, sample manipulation and related hazards. And yet, those factors are responsible of poor reliability, errors of 10% and more in rotational rheometry. The new technique described below claims to have brought mechanics to the same performance as solid-state electronics, and thus having made desappear all major uncertainties in experimental rheometry.
