Eddy-Current Probe Scaling and Gap Voltage Validation
The 102351-04-01 unit supports eddy-current probe scaling for precise displacement measurements. Gap voltage validation against -10 VDC reference targets ensures probe linearity during vibration diagnostics. Rotor dynamics fidelity is preserved through high-frequency sampling, while cross-talk suppression minimizes interference between simultaneous input channels.
Frequently Asked Questions (FAQ)
Q: Can the 102351-04-01 unit be hot-swapped during operation? A: No, insertion or removal under power is not recommended due to bus stability and signal integrity requirements.
Q: What is the maximum sampling rate supported per channel? A: Each channel supports up to 20 kHz sampling, allowing high-frequency vibration capture.
Q: Is the -04 option compatible with modern USB interfaces? A: No, the -04 option provides Enhanced Parallel Port (EPP) connectivity only, requiring compatible field laptops or PCs.
Field Installation Guidelines
- Mount the unit securely in vibration-protected enclosures to avoid mechanical resonance.
- Use shielded cabling for dynamic sensors, grounding shields at a single point to prevent ground loops.
- Maintain separation between sensor wiring and high-voltage conductors.
- Verify polarity and connector integrity before energizing the 24 VDC supply.
- Ensure ambient conditions remain within -40 to +85 deg C for stable operation.
