HBM is a Member of the Western Regional Strain Gage Committee

As a member of the Western Regional Strain Gage Committee (WRSGC), HBM is committed to an open discussion on current topics, future technologies, and challenges around strain measurement. These include the strain gauge as a sensor, data acquisition hardware and software as well as the analysis tools. 

Thanks to the unique exchange of knowledge, we can align our solutions with future requirements to serve our customers’ needs in the best possible way. 

What is the WRSGC?

The Western Regional Strain Gage Committee is a consortium of companies and government agencies mostly from the Western United States devoted to the promotion of a free interchange of information about strain measurement techniques using strain gauges.

The Committee is a technical division of the Society for Experimental Mechanics (SEM), which was founded in 1943. The members of the WRSGC range from strain gauge, transducer and instrumentation manufacturers such as HBM, aircraft companies, national laboratories, propulsion engine manufacturers, government facilities as well as aerospace research and development firms. 

What does the WRSGC do?

The Western Regional Strain Gage Committee organizes two conferences per year to learn more about new developments and research in strain gauges and mechanical testing, and to provide access to networking and discussions with experts in this field.

Presentations and Technical Papers are vital for the WRSGC conferences. They cover a wide range of topics: 

  • Research in the advancement of strain gauge measuring
  • New product development
  • Applications and techniques of measurement
  • Refreshers on core aspects of testing and measurement

HBM: A Member of the WRSGC

Starting with Manfred Kreuzer (former Head of Research and Development at HBM) in the 1980s, HBM is still actively involved in the committee’s conferences. In order to maintain the tradition and the knowledge transfer, HBM product managers Sandro Di Natale and Malte Grieme participate in the conference and present current trends and developments in measurement technology.

HBM Presentations at the WRSGC Conferences

Online, 7October 2020:

Design engineers push designs and materials to their limits to save weight, increase performance or lifetime. To draw watertight conclusions, thousands of strain gauges might be applied to acquire measurement data. But what about the quality of the measurement values?

To assess the quality, the measurement uncertainty needs to be determined. Therefore, all relevant aspects need to be considered. This includes the right choice of gauge, installation, test conditions, influence of data acquisition systems and environments, and many more.

The presentation was held by Sandro Di Natale and gives an overview of measurement uncertainty in strain measurements, showing an exemplary calculation, outlining the biggest contributors and how to minimize their impact.

St. Louis, 10 September 2019: 

In recent years, many industries have shown an increasing interest in composite-based structures in recent years, as there are a lot of advantages such as design flexibility, light weight, high stiffness, lower cost than alloys, and improved productivity. Typical composite materials can resist high strains and it is a challenge to measure these strains with foil strain gauges and adhesives. This presentation shows a new approach to working with strain measurement and the necessary adhesives.

Another challenge is the self-heating effect of measurement points used in composite and plastic materials. Strain gauge construction, excitation voltage, resistance and other parameters influence this self-heating effect and the measurement results. HBM did a Design of Experiment (DoE) study focusing on these effects. Results and recommended best practices will be shown in this presentation by Manuel Schultheiß.

Huntsville, 9 April 2019:

The 'classic' electrical strain gauge has been used for durability testing for 80 years. While the results are accurate and trusted, strain gauge application, wiring and documentation takes a lot of time, especially when testing large structures with hundreds or even thousands of sensors. Various other approaches are now available to determine strain and stress in materials or components: simulation with virtual sensors, camera-based stereoscopy or fiber-based technologies (FBG, OFDR).

With all these technologies available, why should the test engineer bear the time-consuming effort of electrical strain gauge installation?

The presentation was held by Sandro Di Natale and shows the advantages and disadvantages of the different approaches to acquiring strain and stress.
