Measurement at 1,700 degrees Celsius shown at Hanover Messe

1 min read

​The measurement of parts at temperatures up to 1,700 degrees Celsius has been demonstrated for the first time by Germany’s Bundesanstalt für Materialforschung und -prüfung (BAM) organisation, at the Hanover Messe. BAM is a departmental research institute of the German Federal Ministry for Economic Affairs and Energy.

The technology allows the size and form of complex components to be measured during burning or annealing, with changes that emerge during the process can be detected. Any deviations that may later result in the component failing can thus be identified.

The measuring device can be put to use for various manufacturing processes in the future including: the production of additive or conventionally manufactured ceramic components and also the development of metallic components for high temperature applications.

BAM has developed an innovative high temperature laser profilometer, which involves a laser beam being widened and directed onto the sample that rotates within the measuring chamber. The scattered light trace reveals the shape of the sample.

The measuring device is currently being brought to market maturity. BAM will continue to use its expertise in high temperature laser profilometry to test practice-relevant questions, to deepen the scientific basis of the process and to support the dissemination of the method through publication activities
