HIGH PRESSURE CAPILLARY RHEDMETERS

HIGH PRESSURE CAPILLARY RHEOMETER Single- or multi barrel system for determination of the flow- and viscosity function The RHEOGRAPH 20, 25, 50, 75 and 120 with CAN-Bus technology were developed with the experience and potential from more than 40 years of the numerous generations before. A higher rate of automation and user friendliness, a wide shear rate range as well as a testforce, which might be sufficient for many applications come as a standard. Many useful options and nonstandard features can be realized. The integrated color touchscreen, the automatic pressure transducer detection...

Increased accuracy with improvements to the pressure measurement! As an example, a 2000 bar pressure transducer now resolves down to only 0.1 bar, or using a 30.000 PSI transducer that resolves down to only 1.5 PSI. -0,1 Percentage of the nominal pressure [%] The initial situation of the old machine generation Figure 2: Detection of the repeatability with the RHEOGRAPH 2003/6000 at the example of Polycarbonate (or method used currently by all other manufacturers) Figure 3: Detection of the repeatability with the RHEOGRAPH 120 with optimized signal preparation In the figure (3) the same...
