4. Measurement precautions

The file des Techniques de l'Ingénieur (reference [2] ) has highlighted the causes of the main faults that threaten machines, faults that are taken up and illustrated by their vibration image in [BR 5 145] reference [3] , and we have seen, with the preceding examples, the relevance and quality of the interpretations that can be obtained with vibration analysis when the appropriate tools and techniques are used and chosen according to the diagnostic difficulties and economic issues encountered. However, analysis can only be correct if it is based on good measurements, carried out in the best possible conditions for representing the signal emitted by the forces...
