Compact on-line capillary-rheometer for continous measuring of MFR and viscosity functions direct integrated in the production process.

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.

  • Flange-mounted measuring directly on the material supply line, separate Control Electronics
  • Compact size
  • Simple die exchange
  • Large measuring range due to shear rate range of 1:1000
  • System can be operated at a constant speed (shear rate) or constant pressure (shear stress)
  • Operation, evaluation and visual displays are made via personal computer, a built in industrial workstation or from the user side by a process control system
  • Single or multi-point measurements
  • The following test results are supplied depending on the selected operating:
    • Melt index MFR or melt volume index MVR with or without temperature-compensation
    • FRR (Flow Rate Ratio), ratio of 2 consecutive MFR/MVR measurements, which correspond to laboratory tests with different weights
    • apparent shear stress, -shear rate and -viscosity
  • The test results can be::
    • displayed in color on the PC screen
    • supplied via analog 4..20mA
    • requested via host computer connected via serial interface
    • database access via network
    • output in the form of test-data log on a printer
  • The system is also available for use in hazardous areas zone 1 and 2 with the classification "Gas-Ex: Ex II 2G Ex h IIC/IIB T2 Gb X" and "Dust-Ex: Ex II 2D Ex h IIIC/IIIB IP65 Ta,max Db X".
