Specifically designed for the thermoplastics resin industry, the ViscoSensor provides continuous measurements of the melt flow rate or apparent viscosity directly on the manufacturing process.

The ViscoSensor system consists of two parts: a Viscosensor Rheologic Sensing Unit (RSU), connected directly to the process, and a Rheologic Control Unit that controls the Viscosensor test parameters (temperature, pressure, rate), provides outputs of computed results, and provides communications to an external distributed control system when required.
