The Instantaneous angular Velocity Converter (IVC) provides instantaneous angular velocity signal to be analyzed.
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.
The instantaneous angular velocity can be converted to angular position or to angular acceleration using the digital integration and differentiation filters. The obtained angular signal is processed as any other input (or recorded track) of the analyzer. The typical analysis modes are FFT, the order tracking, time domain analysis and waterfall/color spectrogram.
Some special features are available for the analysis of this angular signal:
