Hardware Specifications

Eddy‑Current Scaling & Rotor Dynamics Signal Integrity

The 3300 XL 8 mm probe maintains the standardized eddy‑current scaling used across Bently Nevada systems, aligning with the -10 VDC nominal gap‑voltage reference. The armored cable assembly preserves impedance stability, ensuring consistent displacement interpretation across proximitor channels. The ClickLoc connector maintains coaxial shielding continuity, suppressing cross‑talk and preventing phase distortion during rotor‑dynamic measurements. The Viton O‑ring provides differential‑pressure sealing between the probe tip and case, supporting stable operation in enclosed machine housings.

Frequently Asked Questions

Q: Can the probe be replaced while the proximitor remains energized? A: Replacement should occur only when the monitoring channel is de‑energized to avoid transient gap‑voltage excursions.

Q: Does the 50 mm case length affect electrical linearity? A: Case length does not affect electrical scaling. Linearity is determined by probe geometry and proximitor matching.

Q: How should armored cabling be routed to minimize noise? A: Route the cable away from high‑current conductors and maintain shielding termination at the proximitor end only.

Field Installation Guidelines

• Ensure the mounting surface is clean to maintain proper thread engagement and probe alignment.
• Align the probe face perpendicular to the shaft surface for accurate displacement response.
• Avoid tight bends; maintain a gentle radius to preserve coaxial impedance.
• Bond shielding at the proximitor end only to prevent ground loops.
• Verify gap voltage after installation to confirm correct mechanical positioning.
