Our checkweighers automatically verify product weights during continuous production and packaging processes. Products outside the defined weight limits can be detected and automatically removed from the production line using a suitable reject system.
Modern weighing technology and digital signal processing enable reliable weight control even at high production speeds. The touchscreen control allows product parameters to be managed efficiently and facilitates quick product changeovers.
Depending on the application, our checkweighers can be used as stand-alone systems or combined with metal detectors, conveyor systems, vision systems and additional inspection equipment.
A checkweigher automatically determines the weight of a product while it moves through the production line. The product is transported through the weighing section by conveyor and weighed during the process.
The measured weight is compared with predefined target and tolerance values. If a product falls outside the specified weight limits, it can be automatically removed from the production line using a suitable reject system.
The collected weight data can also be used for statistical analysis and production process monitoring.
The C Series is a versatile checkweigher for automatic weight control of packaged products. Its compact design and flexible configuration options make it suitable for food, consumer goods and packaging lines with high throughput requirements.
Typical Applications
Key Features
The H Series is designed for automatic weight control of large and heavy products. Its robust stainless steel construction and heavy-duty conveyor system enable reliable weight inspection of packaged products weighing up to 60 kg.
The series is particularly suitable for heavy packaging units and industrial applications.
The S Series is designed for precise weight control of small and lightweight products. It is particularly suitable for applications involving small package sizes and demanding requirements for weighing accuracy and throughput.
Typical applications
Our checkweighers can be configured with different conveyor, inspection and reject systems depending on the product and production process.
A checkweigher can be combined with a metal detector to create an integrated inspection system. This allows products to be checked for both correct weight and metal contaminants within the same production line.
Depending on the system configuration, both inspection processes can be combined with conveyor and reject systems as well as additional inspection or labelling equipment.

Weighing & Filling Systems
High-precision dosing and filling technologies for consistent product quality and minimal material losses.
A checkweigher checks the weight of packaged products inline on the production line – fully automatically, precisely, and quickly. It compares the actual weight with a defined target value and rejects products that are too light or too heavy if necessary.
Checkweighers are suitable for:
They are versatile—depending on weight, speed, and line requirements.
A checkweigher measures the final weight of an already packaged product for quality control purposes. A multihead weigher, on the other hand, weighs and combines product quantities before filling in order to achieve the target weight exactly.
Our checkweighers are calibrated (MID-compliant) and meet the requirements of the Prepackaged Goods Regulation (FPVO), LMIV, and EU directives. They automatically document measurement results and are equipped for audits (IFS, BRC, etc.).
Yes—we offer both stand-alone solutions and inline checkweighers that can be easily integrated into sleeve bag machines, filling systems, labeling lines, or metal detectors.
The achievable accuracy of a checkweigher depends on factors such as product weight, product characteristics, conveyor speed, environmental conditions and the specific machine configuration.
Different weighing ranges and levels of accuracy are available depending on the checkweigher series and application. Product characteristics and required throughput should therefore be considered when selecting the appropriate system.
Products outside the specified weight limits can be automatically removed from the production line. Depending on the product, weight and production speed, reject systems can include pneumatic pushers, air jets, drop flaps or diverter systems.
Yes. A checkweigher and metal detector can be combined to create an integrated inspection system. This allows products to be checked for both correct weight and metal contaminants within the same production line.
