Accurately measuring noise and vibrations on rotating and reciprocating machines requires high performance instruments featuring the right functionalities: especially when machines are investigated during run-ups and coast-downs. You will find the adapted analyzing techniques in OROS Rotating Solutions ideal for your machine's variabilities.

Troubleshooting? Investigating?
Accurately and efficiently measuring vibrations requires a simple and comprehensive solution based on precise FFT results.
In the vibration solution, based on OROS analyzers, all the required tools for vibrations analysis are there. In particular, placing automatic max and peak markers will let you spot and report the main frequencies of interest directly.
Furthermore, the multi-analysis and a set of adapted tools open new perspectives to your measurements:
- Increase your comfort and data security with the ability to process FFTs in multiple bandwidths, resolution. Focus your attention on the bandwidth of interest while having an eye on the wide band spectrum.
- Isolate defects from multiple rolls, processing time averaging synchronized simultaneously by 4 different keyphasors. At the diagnostic stage, you will need to go deeper in the determination of the vibration signature. For that purpose, tools such as envelope analysis, zoom analysis, power and side band markers, kurtosis levels, cepstrum, correlation, and more are included.
When studying non-stationary phenomena, looking at their evolution in time or as a function of measured static parameters such as oil pressure or temperature will let you analyze them with a new dimension.

The machine behavior can be somehow different in the field because of the structural coupling with the foundation. Under those circumstances a field test has to be carried out to determine the mechanical impedance of the foundation. ORBIGate® is used for the rotating tests and benefits of the OROS solutions range such as OROS Modal 2 for the other tests. The portability and ruggedness of OROS analyzers is key when realizing these on-site tests. A user-friendly software interface as well as customized report templates are also important in these measurement environments.

A machinery delivery is more than the installation and the start up. For large industrial pumps, turbines, or even compressors the first days must be monitored carefully. During this critical time, misalignments, unbalance or a bearing fault may appear. The same situation occurs when an installed engine or generator shows unpredictable behavior that must be identified prior to stop its exploitation. In order to keep an advanced analysis measurement on such machinery, vibration service test engineers use VibeMaster and additional tools proposed by OROS such as ORBIGate® or Balancing. It operates autonomously, controlling any degradation signs. Automatic alarms, e-mail notifications and, of course, a remote internet control of the current acquisition are some of the VibeMaster features that give them the expected peace of mind.
