Bently Nevada 330102-00-20-10-01-05 3300 XL 8 mm Proximity Transducer System

The Bently Nevada 330102-00-20-10-01-05, also cataloged as the 330102 proximity transducer system, operates as a dedicated hardware component for displacement and rotor‑dynamic measurement within 3300 XL eddy‑current monitoring networks. The assembly uses a 1.0 m coaxial lead and a ClickLoc connector to maintain stable gap‑voltage behavior across standard proximitor interfaces.

Hardware Specifications

Eddy‑Current Probe Scaling and Gap‑Voltage Validation

The 3300 XL 8 mm probe maintains a calibrated −10 VDC gap‑voltage target to ensure linear displacement scaling across its proximitor interface. The 1.0 m cable length is factory‑matched to preserve coaxial impedance, reducing phase distortion during rotor‑dynamic analysis. The armored construction stabilizes signal integrity under vibration, while ClickLoc termination provides repeatable electrical seating and suppresses cross‑talk in multi‑probe installations.

Frequently Asked Questions

Q: Can the probe be removed while the proximitor remains energized? A: Removal should occur only with the channel de‑energized to avoid transient gap‑voltage excursions.

Q: Does the 1.0 m cable length require proximitor recalibration? A: No. The cable length is factory‑matched to standard 3300 XL proximitor modules.

Q: Do hazardous approvals affect electrical performance? A: No. Approvals relate to compliance only; electrical characteristics remain unchanged.

Field Installation Guidelines

• Ensure the mounting surface is clean to maintain stable eddy‑current field alignment.
• Terminate cable shielding at the proximitor end only to prevent ground‑loop formation.
• Avoid sharp bends in the armored cable to preserve coaxial impedance.
• Route probe wiring away from high‑current conductors to reduce electromagnetic interference.
• Verify ClickLoc connector engagement before energizing the monitoring channel.
