{"title":"Série EPRO MMS 6000","description":"\u003cp\u003eLa série EPRO MMS 6000 est un système de surveillance des machines haute performance conçu pour la protection continue des équipements rotatifs à grande échelle. L'architecture repose sur un système modulaire en rack 19 pouces, intégrant des cartes spécialisées pour l'analyse des vibrations, de la vitesse et de la position. Les principales caractéristiques techniques incluent un traitement double canal, des seuils d'alarme programmables et une intégration fluide des données avec les plateformes DCS via Modbus ou sorties analogiques.
