The Online Viscometer was developed with the goal of achieving measurements which are comparable with laboratory results and to provide a system which provides these accurate values permanently and without influencing the process.
The viscometer is fitted between two flange connections. The melt channel can be designed according to the customer´s specifications between D = 20 mm (0.8 inches) and D = 110 mm (4.3 inches). The unit includes the pump drive, the pump, pressure transducers, temperature sensors and the control and evaluation electronics. Electric or liquid/vapor heating is available (optional). The setting of process parameters, the evaluation and the display is realized via a user-friendly touch screen panel or alternatively can be integrated into an existing control system.
An easily exchangeable capillary permits the adaptation of the measuring device to different viscosities ranging from 1 mPas (0.01 poise) up to 20.000 Pas (200,000 poise). A subsequent change of the measuring range is also possible.
Due to the special melt channel design and precise fabrication, dead spots or edges in which shear- and temperature sensitive polymers could possibly stagnate can be avoided. The very short dwell time also prevents accumulations of degraded material. A further innovative feature is the possibility of completely cleaning all parts in contact with the melt without interrupting or disturbing the production process.
