Application 158: Bag Sealer Verification using Subminiature button Load Cells

Application Summary

For sterilized and other sealed pouches and packaging, leaks and partially broken seals are not always apparent. To mitigate seal failure and ensure seal integrity, verification of the heat sealing force is critical, as over/under applied sealing force can cause premature failure of the seal. This application utilises a pair of LLB130 load cells to monitor the force applied to pouch during the pouch sealing process.

Products in Use

FUTEK’s Subminiature Button Load Cell (LLB Series) paired with the IAA series analogue amplifier for feedback into a PLC. View Product Details

How it Works

1. In this application, a pair of Subminiature Button Load Cells is placed so the force exerted on the heater bars by the packaging can be measured.
2. As the pouch moves through the heater bars for sealing, the bars are forced outward, resulting in the load cell buttons measuring the applied force.
3. Utilising two load cells ensures that the heater bars are spread apart evenly and functioning correctly mechanically.
4. The resulting load cell output is then amplified by the IAA series analogue amplifiers for input into the PLC allowing for fault monitoring and pouch seal verification.
