Dynisco ViscoSensor Online Rheometer
Available from Dynisco
Here's what you get when you go Visco:
A capillary viscometer forces material through a small diameter capillary die creating a pressure drop across the die. By controlling the material’s shear rate through the die or shear stress across the die, apparent viscosity or melt flow index is obtained. The ViscoSensor uses differential pressure across the capillary die for either a control point formelt flow index measurement or as a measurement point for apparent viscosity calculations.A wide range of capillary dies are available along with several metering pump choices to fit specific material measurement needs. For example, large length to diameter ratio capillaries can be used to minimize entrance and exit effects of flow.
Minimum Detection Level
Resolution or minimum detection level of a change in material
or contamination is an important criteria. The ViscoSensor will
detect very small changes in viscocity or melt flow rate
of your material. A change of 1 Pa-s or .02 MFR can be seen
in measurement data. These changes in measurement can
be used to quickly adapt the parameters of your process.
