Check Weighing

Packaging Line.jpg

At Kanta King, we offer a range of load cells and instrumentation / electronics designed for accurate, high speed weight measurement and detection of over- or under-weight in check weighing applications.

No matter what type of check weighing system you are designing, Kanta King can offer cost-optimised, reliable, repeatable load cells with the IP rating and level of precision to suit the application ­and high speed, dedicated check weighing electronics ­all with the appropriate trade approvals.

Our Solution

Successful check weighing is the suppression of undesirable dynamic effects.

The advanced fluid damping properties of our load cell will suppress the majority of vibrations, allowing the static weight of the package to be accurately measured while it's in motion.

Furthermore, the weight transmitters are perfect for check weighing systems thanks to their high speed data acquisition rate, their advanced dynamic filtering and their dedicated check weighing software offered as standard.​​

The Background

A check weigher is an automated system designed to check the weight of packaged commodities, to satisfy internal controls and external trade applications.  They are usually found at the end of a production line in many industries, or in the despatch area of eCommerce warehouses.

Check weighers used in legal-for-trade applications require the use of approved components such as load cells and measuring electronics.

There are 2 main types of check weigher;

  • Only the package content is checked; this is needed to calculate a price based on the content

  • The package content is checked and compared with defined upper and lower tolerances in order to accept or discard the package.  These tolerances are mandated, often in accordance with the e-mark legislation.  If a package has a weight outside the tolerance, it is removed from the production line.

For both of these types, the check weighing process can be static (manual) or dynamic.  In dynamic check weighing, the package will be moving along a conveyor belt or roller system.  Therefore, the package’s static weight will be affected by the accelerations and vibrations occurring in the mechanical components of the conveyor.

Typical items that are check weighed for trade purposes:

  • Bottles

  • Cans

  • Pots

  • Bags

  • Big-bags (FIBC)

  • Boxes

  • Packaged meat and fish products
