Railway transport continues to play an important role in the transportation industry; due in large part to its speed, reliability, and affordability. To maintain this viability, ensuring train safety and integrity is key. Stringent regulations are imposed on the inspection of train wheels and axles in both the manufacturing and service sectors. To meet and exceed these strict criteria, Olympus provides the power and flexibility of its FOCUS LT/TomoView package to experienced and knowledgeable integrators, who are then able to deliver fully code-compliant inspection systems.

Le chemin de fer occupe une place importante dans l’industrie des transports, notamment en raison de sa vitesse, de sa fiabilité et de son coût abordable. Il est donc crucial de préserver cette vitalité économique en garantissant la sécurité et l’intégrité des systèmes ferroviaires. L’inspection des roues et des essieux des trains est soumise à une réglementation stricte, tant dans le secteur de la fabrication que dans celui des services. Pour répondre à ces critères rigoureux, et même les dépasser, Olympus offre le système FOCUS PX et le logiciel FOCUS PC qui garantissent toute la souplesse et la puissance requises par les intégrateurs de système chevronnés pour déployer des systèmes d’inspection tout à fait conformes aux différentes normes.
L’unité d’acquisition évolutive FOCUS PX et le logiciel FocusPC sont dotés de la toute dernière technologie par ultrasons multiéléments et conventionnels pour une intégration facile aux systèmes d’inspection automatisés ou semi-automatisés. La capacité du FOCUS PX et de son logiciel à générer et à enregistrer des données brutes C-scan et A-scan en fait le choix idéal pour les applications où le résultat de l’inspection repose sur l’analyse post-inspection des données. Cela inclut notamment les applications des secteurs de l’aérospatiale (stratifié composite), de la production d’énergie (pales d’éolienne), du transport (roues de train), du traitement du métal (pièces forgées), et plus encore.
Offertes en option, les trousses de développement logiciel (SDK) FocusControl, FocusData et OpenView sont compatibles avec l’unité FOCUS PX pour permettre aux clients de développer leur propre logiciel d’application.
