Areas of application for the Bottom up glass inspection system

The Bottom up glass inspection system solves the problems with temperature measurement of Low-E glass with a new approach. By having two infrared imagers installed underneath the tempering line they always measure the temperature on the non-coated high emissivity side of the glass. IR technology development resulting in those new compact designed imagers made this underneath installation possible which was not thinkable before with old bulky line scanners.

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.

In addition to determining the temperature distribution, the system also calculates the glass surface area.

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. These shutters also significantly increase the maintenance intervals for cleaning the optics and completely eliminate the need for additional and time-consuming blowing of the optics with compressed air.

Thermography Software optris PIX Connect included

All IR cameras are delivered with the thermography software optris PIX Connect, which has been developed specifically for the extensive documentation and analysis of thermal images. It allows you to analyse temperature data in real time as well as the remote control of your infrared camera. Furthermore, you can setup individual alarm levels for your process and define visual or acustic alarm signals.

Our thermography software is licence free and can easily be adjusted to your requirements.

All optris infrared cameras are compatible with the Data Aquisition (DAQ) Software Dewesoft X by
