Infrared camera PI 640i G7 series

digitalline-scanindustrial

The Optris PI 640i G7 thermal camera focuses on glass processes in the G7 spectral range (7.9 µm), allowing for reliable temperature readings of glass. It now comes with 120° ultra-wide-angle optics, enabling a single camera to cover large furnaces, float lines, and tempering zones. The lens features a 120° × 100° field of view, making edge-to-edge monitoring possible in tight spaces. Additionally, interchangeable optics ranging from 15° × 11° to 120° × 100° allow users to match pixel coverage and working distance to each task. The detector offers 640 × 480 VGA resolution with a 17 µm pixel size, ensuring that small defects remain visible. Frame rates range from 32 Hz to 125 Hz (in 640 × 120 subframe), allowing fast motion to appear sharp. A 3 × 3 pixel MFOV supports small-spot analysis, making it possible to measure localized hotspots. Furthermore, a software line-scanner mode transforms any detector row into a continuous temperature profile, enabling users to capture both the profile and the full thermal image simultaneously. This setup replaces bulky mirror-based scanners, simplifying installation and maintenance while reducing the overall footprint. Glass measurement relies on emissivity, so the 7.9 µm band matches the high emissivity of typical glass types. This alignment reduces the effects of reflectivity and transmissivity, as well as sensitivity to viewing angles. In its standard range, the camera measures temperatures from 150 °C to 900 °C, covering most glass processes.
