Low-emissivity (Low-E) glass, widely used in energy-efficient windows and façade components, presents unique challenges for traditional infrared (IR) temperature measurement systems. Designed with a special coating to minimize heat transfer, Low-E glass significantly reduces emissivity on one side. This characteristic complicates temperature measurements during production, particularly as glass exits furnaces. Standard IR devices struggle to provide accurate readings through the coated side, leading to inefficiencies and potential quality issues in the manufacturing process. The Bottom-Up Glass Inspection System (GIS) from Optris offers an innovative solution to overcome these limitations. By strategically placing multiple infrared imagers, such as the Optris PI 450i G7, beneath the tempering line, the system measures the temperature of the glass’s high-emissivity, uncoated side. This novel approach guarantees accurate readings regardless of the emissivity challenges posed by coatings. The compact and uncooled design of the PI 450i G7 cameras makes them ideal for tight installations beneath production lines. Previously, such installations were impractical with traditional line scanners, which are large, cumbersome, and installed above the glass. With Optris’s advanced technology, manufacturers can now achieve consistent and reliable temperature measurements crucial for ensuring product quality. The PI 450i G7 infrared camera is a cutting-edge solution tailored specifically for the glass industry. Its design. Operating at a spectral range of 7.9 μm, the PI 450i G7 is perfectly suited for measuring glass temperatures.
