Bently Nevada 330195-02-12-10-00 Proximity Probes Sensor

The Bently Nevada 330195-02-12-10-00, also cataloged as the 330195 proximity probe sensor, operates as a dedicated 8 mm eddy‑current sensing element for displacement and rotor‑dynamic measurement within 3300 XL transducer networks. The assembly implements a factory‑matched coaxial lead, ClickLoc termination, and standardized probe geometry for stable gap‑voltage behavior.

Hardware Specifications

Gap Voltage Validation and Eddy‑Current Scaling

3300 XL probes maintain a −10 VDC nominal gap‑voltage reference, enabling predictable displacement scaling across the 8 mm sensing range. The 1.0 m coaxial cable is factory‑matched to preserve impedance stability, supporting consistent rotor‑dynamic phase tracking. ClickLoc termination ensures repeatable electrical seating and reduces cross‑talk in multi‑probe installations.

Frequently Asked Questions

Q: Can the 330195 probe be replaced while the proximitor remains energized? A: Replacement 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 recalibration is required; the cable length is factory‑matched for standard 3300 XL proximitor modules.

Q: Are there firmware dependencies when installing this probe? A: No firmware resides in the probe. Configuration remains at the monitoring module.

Field Installation Guidelines

• Maintain clean mounting surfaces to ensure stable mechanical seating.
• Terminate cable shielding at the proximitor end only to prevent ground‑loop formation.
• Avoid sharp bends that may alter coaxial impedance.
• Route cable away from high‑current conductors to reduce electromagnetic interference.
• Verify ClickLoc connector engagement before energizing the monitoring channel.
