Thermo Scientific HAAKE Process Control Rheometer – PCR630

The Thermo Scientific HAAKE PCR630 is the latest generation of innovative process control Technology for online rheological measurements of melt index and viscosity.

Applications
The Thermo Scientific HAAKE PCR630 (Process Control Rheometer) measures the melt index at standard ASTM loads and still maintains a minimal lag time which remains almost constant over the melt index measurement range. The slit die pressure control feature allows the HAAKE PCR 630 to operate at pressures above the process pressure, thereby ensuring operation in the linear region of the transducers and preventing out-gassing.

This also allows to cover a wide melt index range and follow transitions with a single die, eliminating costly and trouble some die changes common to other systems. The patented bypass design makes it possible to measure the viscosity at low shear rates without compromising residence time, this results in a much higher sensitivity when comparing different molecular weight materials. The HAAKE PCR 630 can operate in a variety of modes: melt index mode, transition melt index mode, purge mode, viscosity mode (stress control), and combinations of those. The rheometer can report a synthesized Mooney or Intrinsic Viscosity (IV) value – a mathematical calculation from measured shear viscosity data. For ease of operation, recipes consisting of operating parameters and control values, can be stored for various product grades.

The HAAKE PCR630 logs all data and events in a database for trend analysis, SPC reporting and data storage. The HAAKE PCR630 is a ”return to stream” design and is available with a valve block for process isolation and an optical block to allow online spectroscopic analysis (offered as options, additional equipment required). All melts pumps and slit dies are easily exchangeable to adapt the rheometer to specific processes.

Control Features
The Thermo Scientific HAAKE PCR630 electronics, based on the SLC-500® PLC from Rockwell International (Allen-Bradley), provides superior support and integration using industry standard components and technologies.

New software features provide capabilities never before available.
The NEW Process Supervisor for Microsoft® Windows® software, available for the HAAKE PCR630, offers unmatched ease-of- use and an operator friendly design. The software, based on RSView® 32™, is de signed for integration into plant DCS systems. It offers data communication with a variety of protocols like, Data Highway plus®, ModBus® and the latest innovation in process control, OPC (OLE for Process Control). Standard analog signals (4-20 mA or 24 VDC) are also available.

Installation & Maintenance
Installation expertise exists for adaption to extruders from all the major manufacturers. The HAAKE PCR630 is typically installed on finishing and compounding extruders upstream to a pelletiser or mounted as a side stream with a piping adapter. It can be retrofitted to many existing process systems. It is also interchangeable with existing PCR and MFM installations as an upgrade option. The rheometer is backed by a worldwide, direct support system for service and training of plant personnel. We also provide services to assist with the integration of the HAAKE PCR630 in plant DCS systems. The HAAKE PCR630 design concept provides superior ease of maintenance features with its design concept and easy access to all critical components.

The HAAKE PCR630 can be removed from the process by closing its isolation valves and removing only 2 bolts. The vast majority of maintainable components are standard stock items from major vendors of polymer processing hardware.
