ViscoSensor
Product detailed description
THE VISCOSENSOR RSU
The ViscoSensor uses a pair of dosing pumps that isolate it from process, guide the molten polymer through replaceable capillaries and pump the molten polymer back into the process. A three-wire platinum resistance thermometer is used to check and measure the temperature of the molten polymer. Two Dynisco Vertex Mercury Free pressure sensors (now standard equipment) mounted directly in front and behind the die are used to capture the pressure drop across the capillary. VISCOSENSOR RCU: ULTIMATE PERFORMANCE
Our high performance RCU unit combines rheological properties of laboratory capillary rheometer with MFI data provided by laboratory plas. It has been complemented by a Siemens S7-1500 PLC with a 7" (178 mm) Siemens touch panel with HMI touch interface. This combination provides higher computing power and superior graphics, allowing the RCU to provide accuracy of +/- 0.5% over the entire range. ; This allows the RCU to better match measurements with those made by laboratory instruments. In addition, it is certified for potentially explosive atmospheres as required.

VISCOSENSOR e-RCU: PERFORMANCE SIMPLIFIED
The ViscoSensor e-RCU offers a simplified PLC with digital and analog inputs/outputs that most operations need for a cost-effective approach to on-line measurement. It is equipped with a Siemens S7-1200 PLC with a Siemens HMI touch panel with 7" (178 mm) diagonal. This combination provides the system with computing power and top-notch graphics, allowing the e-RCU to provide +/- 2% accuracy across the range. The e-RCU provides the processor with the ability to measure melt flow ratio, relative viscosity, intrinsic viscosity, and melt viscosity in typical end-user environments. All this creates a cost-effective system that reduces the risk of inaccuracy to an acceptable level. If conditions change and the system needs to be used in a hazardous and/or classified location, compatibility with standard RCUs allows for an easy upgrade.
