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.

Sub miniature load cells accuracy

Miniature Load Buttons or Load Cells are traditionally not known for their high accuracy.  However, FUTEK engineers have dispelled this concept by improving the accuracy of this type of product to a Non Linearity of ±0.5% and Deflection of 0.002” nominal.  

Thereby, announcing the FUTEK LLB130, an accurate sub miniature light weight load button load cell.  It has a capacity range from 1000g to 22.6 kg (50 lb), made from a robust 17-4 PH Stainless Steel, it is RoHS Compliant and only weighs 8.5g with a 3.30mm profile height. It is ideal for Press or Inline compression applications.

LLB130 Highlights include

• Fully Internally Temperature Compensated (NO external conditioning circuitry)
• Low Weight
• Low Deflection
• 17-4 Stainless Steel Construction
• Sub miniature size
• Compression
• Uses Metal Foil Strain Gauge Technology
• Also Available with TEDS/IEEE1451.4 Option
