ONLINE RHEOMETER


GÖTTFERT online rheometers provide continuous, real-time data on the properties of polymer melts. This information can be used to make statements about the material's properties and its processability. GÖTTFERT rheometers are compact and easy to integrate into existing processes.

In most applications, online rheometers are used to monitor and control the process of polymer melt extrusion. The high reproducibility of the measured values and the high availability of the rheometer make it an ideal tool for classifying products and ensuring consistent quality.

Online rheometers can also save you money. By automating processes and reducing the need for manual intervention, you can save on labor costs. Better process control can also help you minimize the production of low-quality intermediate products.

With special melt pumps, GÖTTFERT online rheometers can even be used to measure products with recyclate content.

    Realtime Rheometer RTR/RTS

    The REAL TIME RHEOMETER RTR/RTS is a capillary rheometer used in online quality control, which performs measurements on a continuous basis. The unit is used in production control and for monitoring high and low-viscosity polymers in the production and processing of raw materials.

    • MINI BYPASS RHEOGRAPH

    One of the most outstanding features of the MINI BYPASS RHEOGRAPH is its compact size. With a width of approx. 150 mm this new system is one of the smallest online rheometers available. Even in tight space this new design can be installed without problems. The measuring head weight of only 30 kg eliminates costly mounting arrangements. A new die exchange system makes die changes quick and easy.

    • SIDE STREAM RHEOMETER SSR

    The SIDE STREAM RHEOMETER is based on the first melt return online capillary rheometer developed by GÖTTFERT many years ago. The new SSR uses the same annular melt transfer line as the old (the advantage is that only one tap hole is needed, making installation simple) and no waste stream is generated because the tested material is returned.

    • DYNAMIC ONLINE RHEOMETER

    Dynamic tests are required for the determination of the structural properties of Polymers. With previously used Online Capillary Rheometer just the determination of rheological properties in stationary mode was possible. The DOR enables both, simultaneous determination of visco-elastic properties in dynamic mode, as well as the online measurement of viscosity and melt index in stationary mode.
