Abstract. Two alternative experimental procedures for the calibration of tri-axial accelerometers have been compared with traditional methods, performed according stated in standard ISO 16063-21. Standard is carried out by comparison a laser Doppler vibrometer (LDV), used as primary reference transducer. The main sensitivities investigated and, where applicable, also transverse ones. Many aspects evaluated: hypotheses about sensitivities, simplicity procedure, number measurements needed, and...
In the field of vibration monitoring and control, use low-cost multicomponent MEMS-based accelerometer sensors is nowadays increasingly widespread. Such allow implementing lightweight systems with low management costs, power consumption a small size. However, for to provide trustworthy meaningful data, high accuracy reliability are essential requirements. Consequently, metrological approach calibration multi-component sensors, including appropriate uncertainty evaluations, necessary...

Mechanical calibration and traceability of seismometers in operating conditions are still a technical challenge, since very low-frequency ranges (below 0.1 Hz) involved, sensors under investigation generally heavy bulky. Recently, within the vibration metrology field, some pioneering works proposed to evaluate seismometers' sensitivity by applying laboratory mechanical procedures, against primary or secondary standards, according ISO 16063 methods. By following this path, at INRIM, it has...

In spring testing machines, measurement of transversal forces and bending/torsion moments, as well vertical force, is crucial for characterization. For this purpose, the more advanced industrial machines are typically equipped with multicomponent force transducers (MFTs), composed by different sensors each one dedicated to a single component. However, such assembled MTFs present unsolved technical problems, i.e. moment measurements not performed periodic calibration hard manage. To overcome...
