Spotlight: Collaboration Between TrueDyne Sensors AG and BAM

In close collaboration with the Bundesanstalt für Materialforschung und ‑prüfung (BAM), TrueDyne Sensors AG has had its MEMS-based gas sensors scientifically evaluated under realistic, standards-compliant conditions. The tests conducted at BAM are based on DIN standards and demonstrate the reliable measurement of gas concentration—including in hydrogen, nitrogen, and carbon dioxide—across relevant temperature ranges. Furthermore, TrueDyne’s cantilever-based sensors demonstrate high suitability for quantifying hydrogen in (hydrogen-enriched) natural gases as well as for directly determining the calorific value. The results show good to very good agreement with reference measurements using GC analysis. Thus, the collaboration confirms not only the metrological performance of TrueDyne’s sensor technology but also its potential for use in safety-critical and future-oriented applications within the gas infrastructure.
