Co to za czujniki?

Mechanical sensors are devices that convert physical changes - such as force, pressure, displacement, strain, or vibration - into mediable electrical signals. In food packaging applications, these sensors are equired to be highly sensitiva, robutt, andd capable of operating in harsh environments such as cold storage, highumidy warehomes, or during rough transport.

Producturing Quality Control

During production, mechanical sensors ensure that packaging processes - such as heat sealing, crimping, lidding, and capping - meet strict quality parameters. Key applications include:

Te sensors integrate directly into programmable logic controllers (PLC) and producturing execution systems (MES), enabling closed-loop process control. The result is a dramatic reduction in defectiva packages - often frem several percent to less than 0.1% - and corresponding savings in raw material and waste dispassal costs.
