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.

TomoView è un software per PC potente e flessibile, usato per la preparazione, l'acquisizione dei dati, la visualizzazione e l'analisi dei segnali ultrasonori.
Il trasporto ferroviario continua ad avere un ruolo primario nel settore dei trasporti, principalmente grazie a tre fattori: velocità, affidabilità e costi contenuti. Per mantenere tale ruolo è quindi fondamentale assicurare ai sistemi ferroviari un alto standard di sicurezza e di integrità. Nel settore produttivo e manutentivo vengono imposte norme restrittive per l'ispezione di ruote e assili di veicoli ferroviari. Per soddisfare appieno questi severi standard, Olympus fornisce il proprio potente e flessibile sistema FOCUS PX/PC a partner integratori di sistemi di comprovata esperienza e competenza. Questi sono quindi in grado di fornire sistemi di ispezione conformi ai diversi standard.
La modulabile unità di acquisizione FOCUS PX e il software FocusPC integrano le ultime tecnologie a UT convenzionali e phased array per una semplice implementazione nei sistemi automatizzati e semiautomatizzati. Il FOCUS PX, in combinazione con la capacità del relativo software di generare e salvare i dati grezzi C-scan e A-scan, rappresenta la scelta perfetta per le applicazioni nelle quali i risultati di ispezione sono basati sull'analisi dei dati post-ispezione. Questo include applicazioni nell'ambito di diverse industrie: aerospaziale (laminati compositi), produzione energetica (pale eoliche), trasporti (ruote di treni), metallurgia (componenti forgiate) e altre.
Gli opzionali kit di sviluppo (SDK - software development kit) FocusControl, FocusData e OpenView sono compatibili con l'unità FOCUS PX in modo che i clienti possano sviluppare il proprio software applicativo.
