A source of vibration of rotating machinery comes from the instantaneous angular velocity variation of the rotating parts, called torsional vibrations. This widespread phenomenon appears on reciprocating machinery (diesel engines, pumps, compressors), air/water propellers, wind turbines and their transmission. Such vibrations have to be checked for test, validation and diagnostics. OROS, as a specialist of dynamic measurement on rotating machinery, offers torsional vibration measurement as an integrated in the 3-Series analyzers range.
Integrated frequency to voltage converters
The 3-Series analyzers integrate the frequency to voltage converters based on the existing external synch. inputs, used for the measurement of torsional vibration. The Instantaneous angular Velocity Converter software option converts it in an instantaneous angular velocity signal available for the analysis plug-ins. With NVGate, the software platform for OROS 3-Series analyzers, the analyses can be real-time and/or post-processed.
Shaft View and Cross Phase Tracking
Some special features are available for the analysis of this angular signal:
