Présentation du produit
The Bently Nevada 330104-00-04-10-02 is a rugged 3300 XL series 8 mm proximity (eddy-current) probe built for continuous shaft vibration and position monitoring on critical rotating machinery. Designed to pair with 3300 XL Proximitor® sensors, this metric probe delivers clean, high-fidelity signals for protection, vibration analysis and condition-based maintenance. Its compact tip and industrial-grade cable construction make it suitable for installation in turbine, compressor, pump and motor applications where accurate displacement and dynamic vibration data are required.

Predictive maintenance enabler — stable readings reduce false alarms and improve trending for condition-based decision making.
FAQ
What signal chain is required to use this probe?
This probe must be paired with a 3300 XL Proximitor® sensor (or equivalent eddy-current conditioner) and the recommended low-noise extension cable to maintain calibrated linearity and frequency response.
What linear range and sensitivity can I expect?
When used with the matching XL Proximitor®, the typical linear range is 2 mm (80 mils). Exact sensitivity depends on the Proximitor® model and setpoint gap.
How should I set the probe gap during commissioning?
Set the mechanical gap to the mid-bias recommended by the Proximitor® instructions (use a precision feeler or dial indicator), then verify signal bias and linearity under slow roll and run conditions.
Can this probe capture high-frequency events on fast machines?
Yes — in a properly matched probe + cable + Proximitor® chain, usable frequency response extends up to ~10 kHz, sufficient for typical vibration and transient detection.
Are there special grounding or cable routing practices?
Minimize loops, keep probe cable separate from power cables, use continuous shielding, and ensure proper connector seating to reduce EMI pickup and maintain signal integrity.
Can I use multiple probes on the same shaft for orbit analysis?
Yes — orthogonal probe pairs (X/Y) at the same axial plane enable orbit plotting and phase analysis; maintain identical gaps and orientations for best results.
How does target material or surface finish affect readings?
Eddy-current probes assume a conductive target. Changes in metallurgy, surface coating or taper can alter scale factor; calibrate or compensate when target properties differ from standard ferromagnetic steel.
What mounting practices avoid mechanical errors?
Use solid threaded mounting with proper locknuts, avoid cantilever runs, and locate probes where access and axial stability are guaranteed to prevent micro-movement.
How do I verify probe performance in the field?
Perform loop checks with calibrated displacement standards or simulated signals, confirm bias voltage at the Proximitor®, and compare spectral results to baseline measurements.
Can this probe be used on steam or high-temperature casings?
Yes, but verify the complete probe/cable/Proximitor® temperature ratings and select the appropriate high-temperature variant or thermal protection if the installation exceeds standard tip ratings.
