<p>Seismo Wave Company is ongoing improving metrological processes and quality surveys to guarantee the best Infrasound sensors technology. In accordance with our quality approach, a running-in step for infrasound sensors has been investigated and implemented. Once the metrology process is completed (acoustical and electrical calibration, self-noise measurement), objective is to keep monitoring on sensitivity of MB3a sensors during several days, using the in-situ electrical calibration capability. For this purpose, a new bench has been designed and characterized in our laboratory. Different sensitivity assessment methods have been compared. Testing conditions, bench design, methodology and results are laid out in this poster.</p>

Kibble balance experiments have allowed the kilogram to be redefined in terms of the Planck constant. Now that the redefinition is in place, the Kibble balance will allow SI traceable mass (or force) to be realised at any value and at any location. A feasibility study for a novel, scalable electrostatic ‘µKibble balance’, based on the National Physical Laboratory (NPL) next-generation Kibble balance system is presented and its expected performance calculated. A µKibble will allow in-situ, dynamic, small-scale (< g) mass measurements without the current precision limitation caused by subdivision of the kilogram. The measurements will be traceable through electrical calibration rather than transferable mass standards. The instrument will have a wide range of applications in both industry and research.
