This handbook is intended to provide you, the user, with a sol-id basis of vibration knowledge and a useful reference for put-ting this knowledge into practice. Thisguiding principle was first confirmed by OPTALIGN, theworld's first laser shaft alignment system. PRFTECHNIK has a long history of putting innovative techno-logical ideas into industrial maintenance practice - with thepractical advantage for the user always foremost in mind. Vibration measurementis one of the primary measurement methods for determiningactual machine condition and allows a comprehensive evalua-tion through the potential of Fourier transformation. The German DIN Standard 31 051 defines maintenance as allmeasures for retention and re-creation of the specification con-dition as well as for determining and evaluating the actual con-dition of technical aspects of a system. In addition, conscientious maintenance practiceshelp avoid unplanned machine stoppage and the resulting pro-duction downtime while improving production quality andplant safety. Maintenance plays an increasingly important economic role inmodern industry, as managers realize that the key to retaininglong-term investment capital value lies in regular service andinspection.
