L’acc\u00e9l\u00e9rom\u00e8tre de si\u00e8ge SV38V est un acc\u00e9l\u00e9rom\u00e8tre de si\u00e8ge triaxial<\/strong> pour l’ensemble du corps, bas\u00e9 sur des transducteurs MEMS d\u00e9di\u00e9s \u00e0 l’instrument SV106 pour les mesures de vibrations humaines conform\u00e9ment aux exigences de la norme ISO 2631-1,<\/strong> \u00e0 la fois sur un coussin de si\u00e8ge ou un dossier de si\u00e8ge.<\/p>\n

Le SV38V utilise une faible tension et consomme beaucoup moins d’\u00e9nergie<\/strong> que les acc\u00e9l\u00e9rom\u00e8tres IEPE, ce qui prolonge la dur\u00e9e de vie de la batterie de l’instrument SV106. La m\u00e9moire TEDS int\u00e9gr\u00e9e<\/strong> stocke des informations sur la sensibilit\u00e9 de l’acc\u00e9l\u00e9rom\u00e8tre qui sont automatiquement transf\u00e9r\u00e9es \u00e0 l’analyseur de vibrations SV106, ce qui permet d’\u00e9viter les erreurs de configuration.<\/strong><\/p>\n

Le calibrateur de vibrations portable SV111 permet d’effectuer une v\u00e9rification compl\u00e8te de l’\u00e9talonnage in situ selon la norme ISO 8041<\/strong> avant et apr\u00e8s la mesure.<\/p>\n
