Increase machine’s accuracy and throughput by selecting automation components that significantly improve dynamic weighing through faster signal processing and a holistic view of the control chain.

Weight–based control is an excellent choice for many machine builders and system integrators due to higher productivity and consistency of results when compared to other means. Moreover, an added benefit is that weight sensors or scales do not physically contact the products that they are measuring; this avoids cleaning and risk of cross contamination.

While this method can be used for processes measured in minutes or hours, it can also offer significant advantages for high-throughput systems with processes measured in seconds or less.

If your company is developing the latter, there are six key considerations to take into account when crafting machines that function along the automation measuring chain. These considerations are:

  • Latency
  • Filtering method
  • Communication type
  • Networking requirements
  • Controller capabilities
  • Actuator optimization and material

This paper provides detail on all of the above, along with notes that will help you avoid many of the most critical pitfalls when using weight-based control.
