This modified capillary rheometer consists of two interconnected capillary rheometers and can be used in a variety of application testing modes. Thus, both capillary rheometers can be used independently.
The counter pressure viscosimeter is a rheological test instrument for the determination of the viscosity of plastics and flowable materials as a function of the counter pressure. It consists of two interconnected capillary rheometers, which can act simultaneously on a melt sample via a connecting barrel With this modified capillary rheometer, a determination of the flow curve as a function of a precisely defined backpressure is possible.
The pressure transducer signal at the RG 20, RG 25, RG 50, RG 75, RG 120 can be displayed with a resolution of 0.005 % from nominal range, that means 0.1 bar with a 2000 bar transducer.
To ensure highest accuracy all GÖTTFERT pressure transducers are recalibrated specially by a software controlled system.
