METTLER TOLEDO High-Speed Dynamic Checkweighers
METTLER TOLEDO in-line checkweighers are built for demanding production lines. They provide precise weight measurements for every item, without slowing down production speeds. Using advanced digital signal processing and robust weigh cells, these systems offer exceptional accuracy regardless of vibration or line speed variations. Dynamic checkweighers are crucial to helping manufacturers meet net weight specifications on fast-moving production lines, reducing overfill and minimizing product giveaway.
Dynamic Checkweighing Applications

FAQs
Can checkweighers help manufacturers meet regulatory standards?
Yes. Checkweighers play a key role in meeting global weight and measures regulations, such as the U.S. FDA's Fair Packaging and Labeling Act and the EU Pre-Packaged Products Directives. These regulations set Tolerable Negative Error (TNE) limits, which define the maximum allowed underfill before a package is considered non-compliant. METTLER TOLEDO checkweighers automatically reject packages that fall outside the legal weight range and provide a recorded audit trail to prove due diligence.
How do checkweighers support audit traceability and data logging?
Advanced checkweighers continuously log data for every product weighed, including weight, time, date, batch ID, and acceptance status. This makes regulatory inspections easier for agencies like FDA, BRCGS, or IFS, allows quick traceability during investigations, and significantly reduces recall risks by isolating non-compliant batches.
Can checkweighers reduce production costs?
Yes. They mainly cut costs by minimizing giveaway, the extra product that is sometimes added to avoid underweight packages. By weighing each package precisely, checkweighers typically reduce giveaway by 1-3%, delivering a quick return on investment. They also reduce waste by catching underfills before the secondary packaging stage, lower labor costs by automating manual checks, and help avoid costly regulatory fines or customer claims for underweight products.
What checkweigher features suit harsh food production environments?
For demanding environments, a checkweigher should have a rugged, hygienic design. Important features include full stainless steel construction, sealed electronics rated at least IP65 (IP69K for high-pressure washdowns), USDA-accepted design, and smooth surfaces, with minimal crevices, that are easy to clean. METTLER TOLEDO builds its systems to withstand moisture, temperature fluctuations, and corrosive cleaning chemicals common in food processing (e.g., meat and dairy).
What should I look for in a checkweigher for bakery or meat processing?
In bakery and meat processing, prioritize hygiene and product handling. Choose a checkweigher with a USDA-accepted, easy-clean design, IP69K washdown rating, and gentle product handling systems to protect soft goods. Accuracy is key for portion control and cost savings. METTLER TOLEDO offers dynamic weighing solutions designed with these challenges in mind, balancing careful handling, precision, and hygienic durability.
