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. The scanning of a glass part is initiated by the measured temperature, or an external “trigger’ signal. As each heated glass part traverses the field-of-view, a two-dimensional thermal image or “thermogram” is formed. The system software provides features to sub-divide thermal images from MP150 into portions of specific interest, the zones. The zone grid overlaid on the thermal image represents the heating elements in the furnace. Temperatures in each zone can be processed for a certain math function like average, maximum, or minimum temperatures. In case of a thermal defect, the software triggers an alarm. For later analysis, the thermal image is automatically stored in a separate file. The alarm can also be output with an optional digital output module. Through the use of OPC (OLE for Process Control), the GS150/GS150LE system acts as an OPC server and communicates with many common process control systems. This feature allows the GS150/GS150LE to move beyond being just a measurement tool and to become an integral part of the total process control system.
