On-Line Measurement of Rheological Properties

  • John M. Dealy
  • Kurt F. Wissbrun


There are three types of application of on-line rheometers: process monitoring, quality control, and automatic process control. The first type arises primarily in the development of a new material or process, when it is useful to be able to monitor the effects of changes in formulation or operating parameters on product characteristics. In a quality control application, a slow and labor-intensive laboratory test procedure is replaced by a direct indication of product quality. The most sophisticated type of application is in automatic process control, where the rheometer is used as a sensor providing an input signal to the controller. A general review of process rheometers and their applications has been published [1].
