Rotor Dynamics Data Synchronization
The interface unit performs synchronous sampling across all active channels to maintain phase relationship integrity during rotor dynamic analysis. Simultaneous acquisition minimizes timing skew between vibration, Keyphasor, and pressure signals during transient machine events.
When connected to eddy-current proximity probes, the unit preserves probe scaling characteristics required for shaft displacement and orbit analysis. Gap voltage stability near standard -10 VDC operating regions supports accurate waveform capture and spectral processing.
Internal signal routing and DSP processing architecture are arranged to reduce channel cross-talk during high-frequency acquisition cycles and FFT computation tasks.
Frequently Asked Questions
Q: Can the 102351-04-01 operate directly from a 24 VDC field power source?
A: Yes. The unit supports portable operation using a 24 VDC battery or compatible DC supply source.
Q: Does the interface unit support simultaneous acquisition on all channels?
A: Yes. The hardware performs synchronized multi-channel sampling to maintain phase correlation between measurement inputs.
Q: Are mixed transducer types supported within the same acquisition session?
A: Yes. The unit accepts multiple supported sensor types simultaneously, including proximity probes, accelerometers, velocity transducers, and Keyphasor inputs.
