Fill Level Monitoring of Packaged Food Products in Checkweighers with Retro-Reflex Sensors for Transparent Objects
In the food industry, goods that do not meet quality standards are sorted out into checkweighers and placed in containers after the weighing process. In order to check their fill level, a retro-reflex sensor for transparent objects is installed. The set, consisting of retro-reflex sensor and reflector, is aligned in such a way that the light beam is only permanently interrupted at a certain fill level. The sensor then switches and sends the signal to empty the container. Transparent objects made of glass, PET, laminated packaging or trays are reliably detected.
