Bently Nevada 330104-00-02-10-02-00 3300 XL 8 mm Proximity Probes

The Bently Nevada 330104-00-02-10-02-00, also cataloged as the 330104 proximity probe, operates as a dedicated hardware component for shaft‑to‑probe displacement measurement within 3300 XL eddy‑current monitoring systems. The metric M10 x 1 threaded probe establishes a calibrated electrical gap response used for continuous rotor position and dynamic behavior evaluation.

Hardware Specifications

Eddy‑Current Scaling & Gap‑Voltage Validation

The 3300 XL 8 mm metric probe maintains the standardized eddy‑current scaling used across Bently Nevada systems, aligning with the -10 VDC nominal gap‑voltage reference. This ensures consistent displacement interpretation regardless of metric threading or armor configuration. The coaxial ClickLoc connector preserves shielding continuity, suppressing cross‑talk and maintaining stable rotor‑dynamic phase and amplitude measurements. The probe’s PPS tip and SST case materials support predictable thermal behavior across the full operating range.

Frequently Asked Questions

Q: Can the probe be installed while the machine is rotating? A: No. Installation requires a non‑rotating state to ensure correct mechanical positioning and gap verification.

Q: Does the metric M10 x 1 thread affect linearity or calibration? A: Thread type does not affect electrical scaling. Linearity is determined by probe geometry and proximitor matching.

Q: How should shielding be terminated when using armored cabling? A: Shielding should be bonded at the proximitor end only to avoid ground loops and maintain signal stability.

Field Installation Guidelines

• Ensure the M10 x 1 threaded mounting hole is clean and free of debris to maintain proper seating.
• Align the probe face perpendicular to the shaft surface for accurate displacement response.
• Route armored cabling away from high‑current conductors to reduce electromagnetic interference.
• Avoid tight bends; maintain a gentle radius to preserve coaxial impedance.
• Verify gap voltage after installation to confirm correct mechanical alignment.
