This white paper details the main factors influencing the effectiveness of dynamic weighing, and presents several methods of weighing products in motion. The paper looks at the interplay of three key parameters: production throughput, product center distance, and standard deviation. It goes on to explore how these factors are linked in influencing the actual weighing result. We discuss two different load cell types: Strain Gauge Cells and Electromagnetic Force Restoration (EMFR) Load Cells.
The white paper focuses on the following areas in detail:
- The relationship between production throughput, product center distance and standard deviation
- Methods of dynamic precision weighing, including load cell technology and x-ray radio-graphic mass
- Other factors influencing dynamic weighing results
- Weighing technology improvement drivers

While standard deviation, product center distance and production throughput are the three largest factors that determine the quality of the weighing result, other factors can also have a significant impact. Dynamic checkweighing technology takes those factors into account and compensates for them through various technologies including frame construction and the use of software algorithms and sensors.
Improving weighing technology means manufacturers can achieve better weighing results on the one hand, but also grants benefits such as reduced space requirements or better energy efficiency. Software developments mainly focus on improving the algorithms to reduce the standard deviation of the load cell under ideal circumstances. Hardware improvements have mostly centered around the continued miniaturization and speed increases of microprocessors. Regardless of what improvements there are in weighing technology, in the end it all comes down to one thing: finding the right balance between precision and efficiency to deliver the best possible weighing results quickly.
