The unit Is equipped with a powerful and reliable serial data communication system for the exchange of messages between different control un Ita. The CAN protocol is a network suited for "intelligent" devices. All integrated modules such as controllers, sensors, components, etc.,are simply one node within a line of many nodes. The nodes are connected In a certain order while each individual node is configured and allocated to a corresponding drive attachment.

2 Since the lntelli-Torque is comprised of self-intelligent modules, the instrument Is capable of self-diagnostics and registration. During start-up and initial operation, nodes are contacted to run a self-test. In the event of an error detection a transmission corresponding to the error is clearly defined along the bus. The information is then displayed on the operator's PC. It eliminates the onerous task of trial and error play by pinpointing the faulty apparatus. Conical Twin Screw Extruder Extrusion Applications WI NEXT WINEXT is the custom designed Brabender Windows .. software extrusion program for the lntelli-Torque Plasti-Corder torque rheometer. The software fulfills a dual role of controlling the operation of the Plasti-Corder-from the computer keyboard while monitoring and recording important extrusion process Information. It can be used with any Windows .. compatible Plasti-Corder and Brabender single-screw or twin-screw drive attachments.

3 WINEXT functions along with the lnteiii-Torque CAN (Controller Area-Network) Field Bus communications system to guarantee trouble-free rheometer and sensor operation. The software has been programmed for easy operation by the user from startup to finish. Upon entering the program, the user can input information about the sample as well as setup the equipment configuration. Alarms can be set to notify the operator of deviation from pre-established process limits. The software can govern the Independent speed control for a gear pump or post-extrusion equipment. It can also interface with a pressure sensor for pressure feedback speed control. Once an extrusion trial has commenced, the software provides real-time process Information such as: process torque extruder speed melt temperature(s) for up to four melt thermocouples melt pressure(s) from an unlimited amount of pressure transducers A real-time graphic displays how the process variables interact.

4 The operator has the ability to change the extrusion speed and temperature simply by entering a command from the keyboard. Data can be stored, recalled and printed upon completion of the extrusion run. The software prints out data In convenient columns or can be exported to a spreadsheet. Data can be graphed to show the relationship of process variables with respect to time. The printouts create a definitive record of a specific extrusion trial. Ultimately, the WINEXT program gives the researcher the tools and data gathering capability to investigate how process conditions affect the performance of a specific material/compound in an extrusion process. 20mm Clamshell Segmented Twin-Screw Extruder Attachment Software WI NEXT -'!"-, -'+-!:-. -!:-,. -+. -+. -+. ~. ~~--.~ .. --.: Extrusion trial -I --I \ L--1 -"'""" I ,.. ~ -1 l '\, r -,- '--I _ I ! -d ~ - i I I --I -.

6 WIN MIX applications software program features distinct evaluations for PVC, elastomers, ceramics, thermosets, engineering resins, and thermoplastics, there is a mixing evaluation for every need. The torque curves and the data they generate characterize the material's flow behavior in accordance with today's standard practices and protocols.

The WINMIX Program also provides a Note Pad feature, which allows a notation to be Inserted on a curve.

7 Notations can be recorded while the test Is In operation, or once the teat has been completed. Type Six Mixer Mixing Applications MIXCORR The MIXCORR Program Ia a Mixer Data Correlation Statistical Analyala Software Program, enabling the operator to overlay multip le curves and evaluate the data graphically and/or statistically. It is an affective means of further analyzing mixer torque and processing data. In practice, it is helpful in solving processing problems with new formulations. The MIXCORR Correlation Program can be used to compare mixer tests that were run under identical test conditions for the same material. Mean values and standard deviations are calculat ed, and reference curves with tolerance limits can be determined. This additional feature enables the operator to develop an average statistical curve for Research & Development, Product Development and Quality Control applications.

8 When the tolerance limits have been determined, the data can be compared directly with plant proceaalng conditions. The MIXCORR program can be utilized to develop the Mean and Standard Deviation for a wide variety of mixer applications. Repeatability of PVC Fusion Curve from 5 Individual Fuelon Teats ..

Brabender Instruments, Inc. provides the latest method for predicting the processability of cellular polymers. Technological advancements in mass flow transducers and data acquisition systems have dramatically improved the accuracy and rei iability of the generated data. The resultant data yields Important processing Information that simply cannot be obtained by any other laboratory Instrument.

9 By measuring real-time mass flow, while simultaneously measuring polymer rheology, today' s polymer scientists can readily predict how foam formulations will behave on a larger scale. Through the means of the WIN MIX Gas Evolution Analysis Program, a precision mass flow transducer, a two piece Mixer/Measuring Head with Gasketed Ram Closure, and Viton Flouroelastomer 0-Ring shaft seals, all generated gases are measured in Standardized Cubic Centimeters (SCCM).
