New Optris bottom up system for glass tempering plants

In order to achieve high energy efficiency in buildings, Low-E glass is used for windows and facade components.

The low emissivity poses a major challenge for infrared devices which are traditionally measuring the glass temperature from above when the panes move out of the furnace.

The new Bottom up GIS solves this problem with a new approach.

By having two infrared imagers installed underneath the tempering line they always measure the temperature on the uncoated high emissivity side of the glass (1,600 pixels scan line resolution and maximum field of view of 111°/4.3 m scan width).

Both infrared cameras are reliably protected against glass breakage by an optris CTlaser 4M pyrometer in combination with the digitally controlled optical protection system (DCLP - two automatic shutters).

The installation is possible in a very small space and an exact mechanical positioning of the system, which was previously done with old, bulky line scanners, is no longer necessary.

The exact alignment of the scan line can be conveniently performed using the Optris software supplied.
