Function – efector octavis supports machine-integrated condition monitoring. The target was to develop machine-oriented vibration monitoring. efector octavis should not only detect vibration data but also perform the requested signal analysis and machine diagnosis already on the machine. The machine condition can be determined right on the site of measurement and be signalled via binary alarms or as a diagnostic protocol to higher-level controllers. Three requirements of modern machine monitoring are met: compatibility, scalability and repeatability. Compatibility with existing data structures enables full integration of condition information in higher-level systems. Scalability is an important requirement which allows companies to obtain modular extension of condition monitoring of machinery and plant. High repeatability of < 5 % as well as a linearity error < 1 % provide optimum prerequisites for reliable (online) monitoring of long-term stability. It is also important that monitoring is permanent and in real time to enable quick action in the events of slow development of damage such as rolling element bearing damage and of quick development of damage such as unbalance on spindles.

Vibration diagnosis Vibration diagnosis provides most comprehensive information for early damage diagnosis and for judging operating conditions. efector octavis continuously detects, analyses and evaluates vibrations on the machine surface. The following damages and operating conditions can be reliably detected already at an early stage by means of vibration diagnosis: Rolling element bearing damage Damage to Couplings Rubbing Gear-mesh damage Unbalance Alignment condition Cavitation External influences (e.g. crash) Metal cutting operations (on machine Tools) etc.
