Bently Nevada 330103-00-03-05-12-00 3300 XL 8 mm Proximity Probe
The Bently Nevada 330103‑00‑03‑05‑12‑00, also cataloged as the 330103 3300 XL 8 mm Proximity Probe, operates as a dedicated sensor for static shaft position and dynamic vibration measurements within machinery protection systems.
Miniature coaxial ClickLoc with Proxpact molded protection
Agency Approval
None

Standard 3300 XL extension cables and Proximitor sensors
Eddy-Current Probe Scaling
The 330103 probe employs eddy‑current scaling to convert shaft displacement into a proportional voltage signal. Gap voltage validation (targeting approximately ‑10 VDC reference) ensures linearity across the 2 mm measurement range. This scaling behavior is critical for rotor dynamics analysis, enabling accurate vibration diagnostics and suppression of cross‑talk between adjacent probes in multi‑channel monitoring systems.
Frequently Asked Questions
Q: Can the 330103 probe be hot‑swapped during operation? A: No. Probes must be disconnected only when the system is de‑energized to preserve calibration integrity.
Q: How does the probe maintain interchangeability? A: It is factory‑calibrated and fully compatible with 3300 XL extension cables and Proximitor sensors without requiring bench recalibration.
Q: What is the typical output sensitivity? A: The probe provides 200 mV/mil across its defined linear range.
Field Installation Guidelines
Do not cut or modify the probe cable; factory termination preserves calibration.
Maintain proper bend radius to avoid altering coaxial geometry.
Route cables away from high‑frequency switching conductors to reduce induced noise.
Ensure ClickLoc connector is fully seated before energizing the system.
Avoid mixing XL probes with NSv probes to prevent impedance mismatch.
