RMP-FoU Repeatable Shocks

Aim and goal

The project aimed to enhance the capability of the National Laboratory to realize dynamic pressures. The goal was to give the National Laboratory equipment greater freedom in realizable pressures and better repeatability in realized amplitude.

Challenge

In metrology the ability to make traceable measurements with low uncertainties of rapidly varying (dynamic) pressures is highly aimed at. Difficulties include realizing dynamic pressures with known and well-defined amplitude and phase. Presently, accepted international comparisons validating the capabilities are also lacking.

To attain well-defined realizations of highest international relevance precision of the present National Laboratory equipment must be improved.

Solution

This project aimed to developing new components that improve the repeatability and decrease the uncertainty in input parameters thus increasing the knowledge of the realized dynamic pressures.

Effect

After this project Swedish National Laboratory for pressure becomes able to deliver high quality dynamic pressure measurements. The project results is published in the scientific journal Sensors. In the long run this implies that traceability in dynamic pressures could be distributed and thereby  enabling more accurate measurements that in turn could lead to more effective use of chemical fuels.
