In growing numbers, paper companies are realizing the benefits of Infrared Thermography as a troubleshooting tool, especially as it relates to determining the source of cross direction moisture variations in the sheet. The detailed Infrared Analysis, in most cases, can quickly determine the origin of the process-related problem causing the moisture variation. The variations in sheet moisture at the reel are usually found to be occurring at the wet end, directly correlate with temperature differences.
