A sense for see-through bottles

A transparent-object sensor has been introduced, which is specifically designed for the food and beverage industry. It is said to offer better detection of objects such as glass bottles, polyethylene terephthalate (PET) bottles, transparent trays or packaging film.

The E3S-DB from Omron has high-sensing stability, which makes it ideal for detecting all kinds of transparent objects found in today's food and beverage packaging processes. To enable high-precision detection and positioning on conveyors where the smallest of gaps between bottles exists, the E3S-DB is also available in narrow-beam models with a convergent beam that has a focused spot size of just 2mm at a distance of 200mm.

To meet the trend towards the use of thin PET bottles in the beverage industry, the sensors apply a technique known as P-Opaquing, which offers increased detection stability through special polarising filters for PET objects.
