What is Checkweighing?

Checkweighing means to compare the weight of a product against preset limits. The Checkweighing system will check weights of products whilst in motion, rejecting any products that are over or underweight. For example, if you’re selling a box of chocolates, you want to ensure all boxes are the same weight so that people pay the same price for the same amount. So, if the boxes are labelled 500g, you can put each box on the scale to find out if it’s under, over, or within a weight range of your choosing. The machines can achieve in min weight operation or average weight modes. It allows you to tighten up on current average weight legislation but won’t allow you to go outside keeping our customers compliant. Checkweighers can also be integrated with other inspection equipment such as Metal Detectors, X-Ray and Label Verification to help save valuable production space.

How does a checkweigher weigh a product?

The product is weighed and monitored whilst it is moving on the production line usually at the end of the line when the product is packed and finished. Generally, the product enters the checkweigher via an infeed conveyor to ensure the pitching between products is correct. It is then dynamically weighed on the weigh table before being moved on to the outfeed where good products will pass through or out of tolerance products will be rejected from the line. The product is weighed multiple times whilst travelling across the weighing conveyor and the average is calculated.

What industries use Checkweighers?

They are seen in the largest volumes in the food and pharmaceutical sectors. However, they are used in all industries where a product is being sold by a declared weight or count. They can also be configured and integrated with other inspection equipment such as Metal Detectors, X-Ray machines, seal testers & label Verification systems are used and sold based on weight, the food industry relies heavily on Checkweighers.

Why are so many companies now using Checkweighers?

They also have a number of fail-safe features that are insisted upon by the major supermarkets and BRC etc. When used in conjunction with Metal Detection and X-Ray equipment they form a Critical Control Point (CCP) to ensure consistent quality even on the highest volume lines.
