Product overview
The ES150 Sheet Extrusion Process Imaging System is an automated inspection system for detecting, measuring, and classifying defects occurring in sheet extrusion, cast film and web processes. The ES150 system continuously monitors the web process allowing temperature data to be visualized as a line graph (profile) and a thermographic image. Profiles and images may be printed or archived for analysis.
Through the use of OPC (OLE for Process Control), the ES150 system acts as an OPC server and communicates with many common process control systems. This feature allows the ES150 to move beyond being just a measurement tool and becomes an integral part of the total process control system.
Software
The ES150 System provides the capability to define any number of sectors corresponding to specified areas across the sheet. Sectors are defined by name, location, and the desired processing of temperature data within the sector (e.g., average, minimum, or maximum temperature).
This capability is very useful in sheet and cast film extrusion processes where sectors can be configured to provide temperatures corresponding to each die bolt heater. In case of an alarm, information is automatically saved indicating the time, alarm duration, and the defect position. When an alarm trigger occurs, 500 temperature lines are automatically stored in an alarm log file.
