EC150 Infrared Temperature Measurement for Extrusion Processes - 1

Process Imaging System EC150 Infrared Temperature Measurement for Extrusion Processes Benefits ■ Detect “wavy” or “running” edges, gaps, and torn edges quickly and automatically ■ Insure proper web temperatures for strong film-to-substrate adhesion ■ Automate quality monitoring for ISO 9000 ■ Improve profitability and product quality ■ Reduce scrap Quality Monitoring for Extrusion Processes ■ Detailed web temperature profile based on 40,000 measurement points per second ■ Define product-specific configurations (recipes) ■ Automatically analyze “automatic sector” temperature distributions ■ Play back stored files as “movie” ■ PC independent alarms ■ Integrated OPC server for remote system control ■ Analog or digital output modules ■ On board Ethernet TCP/IP communication ■ Built-in laser sighting ■ Multiple language support The EC150 system is an automated surface inspection system for detecting, measuring, and classifying defects occurring in extrusion coating, co-extrusion and laminating processes. Surface temperature measuring of the melt curtain supplies the information about available temperature distribution at the die exit. The EC150 measuring system offers a noncontact temperature measurement covering the entire width of the polyethylene film. The linescanner scans the melt curtain directly. For a better alignment the linescanner is equipped with a line laser. Core of the system is the MP150 linescanner. The MP150 measures a line of up to 1024 points using a rotating mirror that scans a 90° field-of-view up to 150 times per second. The high scan rate allows rapid detection of temperature non-uniformities and hot spots. As the band traverses the field-of-view, a two-dimensional thermal image is formed. Through the use of OPC (OLE for Process Control), the EC150 system acts as an OPC server and communicates with many common process control systems. This feature allows the EC150 to move beyond being just a measurement tool and to become an integral part of the total process control system. SIRaytek Fluke

EC150 Infrared Temperature Measurement for Extrusion Processes - 2

System Description Melt Curtain Optical Resolution 225:1 (50% energy) Ambient Temp. 0 to 50°C (32 to 122°F), with Substrate Unwind Chill Roll Points per Line 256 pixels @ 150 Hz Automatic Edge Detection The “Automatic Sector” feature, unique to EC150, continuously monitors the whole melt curtain and provides automatic edge detection. The “Automatic Sector’ automatically adapts to measuring a plastic film of varying width. Temperature gaps or unacceptable “waving” or “edge running” are detected automatically from one scanned temperature line to the next. If a fault or defect occurs, an...
