Presence check of the best-before date on the neck of the bottle
The precise inspection of the best-before date at high speed places high demands on image processing – especially when changing products. This article describes how the combination of a powerful control unit, machine vision camera and optimized print positioning creates stable contrast even in dark liquids, enabling reliable high-speed control.
How can steel and stainless steel sheet metal strips be reliably detected?
Inductive sensors can be used to detect steel and stainless steel sheet metal strips reliably, contactlessly and reliably. Correction factor 1 sensors ensure identical sensing distances for different metals.
How can scratches and dents on large metal surfaces be reliably detected?
2D/3D profile sensors enable the precise detection of scratches, dents and other irregularities on large metal surfaces – even in the presence of movement and reflective materials. They deliver micrometer-precise measurements, cover wide areas and ensure reliable quality control in industrial production.
Precise sensor technology for secondary packaging
wenglor shows how sensor solutions reliably detect cartons, boxes and transparent objects in secondary packaging and thus ensure process reliability.
