Fluke Process Instruments combines two devices using two different temperature measurement technologies, the Datapaq Furnace Tracker and the Raytek MP150 infrared linescanner. Datapaq profiling systems travel through heat-treatment and quench processes, recording the product temperature curves via up to 20 thermocouples cemented to the glass pane. The Raytek MP150 infrared linescanner scans each glass pane when it exits the furnace and generates a thermal image that displays hot and cold spots.
