Abstract
La présente invention se rapporte à un dispositif de surveillance de bruits de vibrations dans les corps solides d'une installation. Selon l'invention, on forme dans le canal de mesure du système de surveillance un seuil Ug correspondant à un multiple de la valeur moyenne amplifiée Um de la valeur de mesure U8 . Lorsqu'un nombre réglable d'amplitudes Us , de la valeur de mesure a dépassé le seuil pendant un temps réglable, il y a production d'un signal d'alarme U120 . L'avantage de ce système réside dans le fait que le déclenchement du signal s adapte automatiquement aux variations du niveau du bruit de fonctionnement. Application : réacteurs nucléaires.
