Infrared camera for temperature measurement in the glass industryHigh-resolution IR camera optris PI 640 G7 from 5572 £

The optris® PI 640 G7 infrared camera is the first industry-specific thermal imaging camera in the PI series. Designed specially for the glass industry, this camera measures in only one spectral range.

The typical parameters of Optris cameras – high measurement speed (80 Hz), high optical resolution (640 x 480 pixels) and compact design – were kept to allow for the capturing of real-time thermal images of everything from glass beads right up to large panes.

The IR camera is used as a line-scan camera in the field of sheet glass production and offers various possibilities for documenting and controlling the process.

This compact, high-performance infra-red camera for the glass industry is available with interchangeable lenses and industrial accessories. The comprehensive license-free software package “optris PIX Connect” is included in the price.

Thermal imaging camera optris PI 640 G7 – Areas of applications

The optris PI 450/640 G7 infrared camera, which was specially designed for the glass industry, can be used for various tasks in the production, refinement and processing of glass panes, glass bottles and other glass products.

The software offers a line-scan camera function which, in the tempering of toughened glass for instance, measures the temperature distribution between the heating zone and the cooling zone, and automatically regulates heating or cooling elements where necessary.

Thermography software optris PI 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.
