Un capteur acc\u00e9l\u00e9rom\u00e8tre<\/strong> convertit les vibrations en un signal \u00e9lectrique.<\/p>\n

Le type de sortie<\/strong> d\u00e9termine la mani\u00e8re dont ce signal est transmis et la fa\u00e7on dont il r\u00e9siste au bruit ou \u00e0 la perte de signal.<\/p>\n

Les acc\u00e9l\u00e9rom\u00e8tres MEMS<\/a> Recovib\u00ae de Micromega Dynamics<\/strong> supportent les principaux formats industriels – boucle de courant 4-20 mA<\/strong>, tension<\/strong>, tension diff\u00e9rentielle <\/strong>– garantissant des donn\u00e9es pr\u00e9cises et stables du courant continu \u00e0 plusieurs kilohertz.<\/p>\n

Sortie analogique<\/h2>\n

Un acc\u00e9l\u00e9rom\u00e8tre analogique<\/strong> d\u00e9livre un signal continu proportionnel \u00e0 l’acc\u00e9l\u00e9ration.<\/p>\n

C’est le format le plus courant et le plus polyvalent, compatible avec la plupart des syst\u00e8mes d’acquisition et offrant une r\u00e9ponse en temps r\u00e9el sur une large gamme de fr\u00e9quences.<\/p>\n

Micromega fournit des sorties analogiques en tension<\/strong>, en tension diff\u00e9rentielle<\/strong> et en boucle de courant 4-20 mA<\/strong>, ce qui permet aux ing\u00e9nieurs de s’adapter \u00e0 la distance, \u00e0 l’environnement sonore ou aux besoins d’int\u00e9gration des automates programmables.<\/p>\n

Gr\u00e2ce \u00e0 cette flexibilit\u00e9, les capteurs Recovib\u00ae conviennent aux applications de g\u00e9nie civil<\/strong>, de surveillance des machines<\/strong> et d’\u00e9oliennes<\/strong>.<\/p>\n

Sortie courant (4-20 mA)<\/h3>\n

La boucle de courant 4-20 mA<\/strong> est id\u00e9ale pour les environnements industriels n\u00e9cessitant de longs c\u00e2bles<\/strong> ou une grande immunit\u00e9 au bruit.<\/strong><\/p>\n

Le signal reste stable sur des distances sup\u00e9rieures \u00e0 150 m et se connecte directement aux syst\u00e8mes de surveillance standard.<\/p>\n

Micromega int\u00e8gre cette sortie sur les capteurs Recovib\u00ae pour simplifier le d\u00e9ploiement sur le terrain et r\u00e9duire les probl\u00e8mes d’interf\u00e9rence.<\/p>\n

Tension de sortie<\/h3>\n

Un acc\u00e9l\u00e9rom\u00e8tre \u00e0 sortie tension<\/strong> (par exemple, 0-5 V ou \u00b110 V) est simple \u00e0 utiliser et facile \u00e0 interfacer avec des installations de laboratoire ou de surveillance locale.<\/p>\n

\u00c9galement int\u00e9gr\u00e9 dans les acc\u00e9l\u00e9rom\u00e8tres micromega, il offre une haute r\u00e9solution et une r\u00e9ponse rapide pour des longueurs de c\u00e2ble courtes \u00e0 moyennes<\/strong>, ce qui en fait un choix privil\u00e9gi\u00e9 pour les bancs d’essai et les mesures sur site.<\/p>\n

Sortie de tension diff\u00e9rentielle<\/h3>\n

Un acc\u00e9l\u00e9rom\u00e8tre \u00e0 tension diff\u00e9rentielle<\/strong> envoie deux signaux compl\u00e9mentaires – l’un positif, l’autre invers\u00e9 – et mesure leur diff\u00e9rence.<\/p>\n

Le bruit \u00e9lectromagn\u00e9tique est ainsi annul\u00e9, ce qui garantit une grande pr\u00e9cision, m\u00eame avec de longs c\u00e2bles.<\/p>\n

Il est id\u00e9al pour les applications \u00e0 faible bruit ou \u00e0 haute r\u00e9solution<\/strong>, telles que la fabrication de semi-conducteurs ou la surveillance de l’\u00e9tat des structures.<\/p>\n

Les mod\u00e8les IAC-HiRes<\/em> et IAC-UHRS<\/em> de Micromega peuvent \u00eatre param\u00e9tr\u00e9s avec cette sortie pour une stabilit\u00e9 et une pr\u00e9cision exceptionnelles.<\/p>\n

Sortie num\u00e9rique<\/h2>\n

Un acc\u00e9l\u00e9rom\u00e8tre \u00e0 sortie num\u00e9rique<\/strong> convertit les donn\u00e9es analogiques en donn\u00e9es num\u00e9riques (SPI, I\u00b2C, RS-485) avant de les transmettre.<\/p>\n

Elle offre une forte immunit\u00e9 au bruit et une int\u00e9gration transparente dans les syst\u00e8mes embarqu\u00e9s, mais elle est moins adapt\u00e9e aux longues distances.<\/p>\n

Les sorties analogiques (tension ou courant) restent la norme pour la surveillance industrielle robuste.<\/p>\n
