Checkweighers are a vital piece of weighing equipment for manufacturers globally and are a robust piece of equipment used by many of our food manufacturing customers who rely on them daily to meet legal product requirements.

This article explains five key reasons your business should invest in a checkweigher system , which include:

  • Information instantly available
  • Improved production efficiency
  • Comprehensive, 100% sampling
  • Monitoring standard deviation
  • Legal compliance

Read on below to learn more about the benefits of having a checkweigher machine on your production line.

Information instantly available

A checkweigher is an electronic weighing machine with software that measures and records the machine’s workings. When in use, all product weights are captured on the loadcell that communicates to a PLC which is interfaced with the software. This data is captured in real-time and is available via the control panel interface, terminal, or software via a management pc.

Improved production efficiency via Count/Weight

Using a checkweigher, you can be assured that every product from your batch will be counted with weights recorded. In addition, any underweight, overweight, or rejected products will be weighed and recorded, giving you electronic data records that are available in real-time for decision-making, as well as accessible electronic records available at the touch of a button for audits.

Comprehensive, 100% sampling

Unlike sporadic manual sampling offline, a checkweigher conducts 100% sampling of all products in the production batch which pass through the checkweigher. This gives the manufacturer complete peace of mind that the product weights within the batch are within tolerance, meet average weight legislation and any deviations can be highlighted and managed quickly and accordingly.

Monitoring of standard deviation

Checkweighers will monitor and record standard deviation data for the weights of products in a batch. Unlike the Mean calculation, which may result in an under or overweight average weight of a batch, standard deviation provides a better measure of the batch and focuses on the data around the Mean. This gives manufacturers more flexibility particularly when dealing with vast volumes of products and allows them to reduce the standard deviation, if required, for a better result, reducing product giveaway.

Legal compliance

Meeting legal compliance with checkweighers typically involves adhering to regulations and standards set by local authorities or relevant industry bodies. While specific requirements may vary depending on the intended application of the checkweigher, here are six ways a checkweigher can meet legal compliance:

  • Weighing Regulations
  • Documentation and Records
  • Quality Assurance Systems
  • Labeling and Packaging Requirements

It is important to note that the specific requirements for legal compliance may vary based on factors such as the industry and product type in which the checkweigher is being used. We recommend always speaking to and seeking advice from your local authority for guidance on requirements in your industry.
