Gneuss: Online Viscometer for reliable viscosity measurement
 Gneuss has developed a compact unit for monitoring and recording of the rheological parameters. The Online Viscometer is designed with an extremely compact housing for installation for example between flanges. The melt channel can be specified to match the existing melt channel diameter between 20 and 110 mm. The unit is supplied complete with pump, pump drive, pressure transducers, temperature sensors and the control, evaluation and visualisation system. Advert The adjustment of the processing parameters, evaluation and visualisation is carried out via a user – friendly operator interface (touch panel). The electrical equipment can of course be incorporated in an existing control system.
The unit monitors and display the values for viscosity and shear rate in addition to monitoring the melt temperatures and pressures. The Online Viscometer offers the following advantages: • Short residence time, no dead spots, no deposits in any of the melt channels. • The measurement in a square cross section capillary excludes the influence of elastic properties of the polymer. • The measurement is carried out in bypass – no polymer loss. • Minimum temperature deviation (< 2°C) among all parts in contact with the melt. • Complete cleaning of all parts in contact with the melt possible without stopping or disturbing the process. • Compact design, flexible adaptation to existing melt pipe or extrusion line.
