| Abstract Scope |
In this work we report the development of an optimized magnetoelastic sensor designed for operation in harsh atmospheric conditions. We studied the effect of incorporating chromium and nickel into the sensor composition to improve its corrosion resistance. We have fabricated a rhombus-shaped sensor and driven the sensor to the crystallization by thermal annealing to maximize its sensitivity. We have achieved an increase of 80% in the resonance frequency value compared to the traditional rectangular and as quenched sensor. The resulting sensor exhibits a sensitivity of 13 Hz/µg, representing an improvement over magnetoelastic sensors with similar dimensions. In addition, temperature calibration was performed to assess thermal effects on the sensor response. Corrosion tests were also carried out on both crystallized and non-crystallized sensors to evaluate the impact of thermal treatment. The obtained results demonstrate a clear enhancement in the performance, making these sensors promising candidates for applications in adverse environmental conditions. |
