One-sided thickness measurement of container glass

Wall thickness and roundness of the bottles are crucial parameters that define quality in glass production. They must be thoroughly inspected during the production process. The faulty products, if found, should be rejected and directly returned to the glass melt for further processing.

Manufacturers need a fast and automated inspection system due to the high processing speed. This particular measurement application requires a non-contact sensor as any damage to the bottles is not tolerated. The system consisting of confocalDT2422 dual channel measurement system and IFS2406-10 confocal sensors are ideally suited for this measurement task as they are capable to measure the distance and thickness of transparent materials synchronously on two points. The sensors can be easily adapted to different glass colors due to automatic exposure control feature.
