Optris has announced a new glass inspection system that provides a fresh approach to temperature measurement in the production of low-e glass. Low emissivity glass poses a major challenge for infrared devices which are traditionally measuring the glass temperature from above when the panes moved out of the furnace during production.
The new bottom-up glass inspection system solves this problem by having two infrared imagers installed underneath the tempering line which measure the temperature on the non-coated high emissivity side of the glass.
The combination of two VGA imagers with a maximum field of view of 111° results in an excellent 1600 pixels scan line resolution on maximum 4,3 m scan width.
An ultra-fast CTlaser 4M pyrometer with 90 µs exposure time combined with the digitally controlled lens protection system (DCLP) is a reliable safeguard for both infrared cameras in case of glass breakage.
Important Specifications
- Compact bottom up system for coating independent
underneath measurement - Integrated ultra-fast glass breakage detection combined
with Digitally controlled lens protection system (DCLP) - Pre-assembled system for easy installation on glass
tempering furnaces - Glass area calculation
