Technical Specifications

Solving the Discontinued Hardware Crisis

The Bently Nevada 3300 XL proximity transducer system was the industry standard for shaft vibration, position, and speed measurement on critical rotating equipment — steam turbines, gas compressors, centrifugal pumps, and large motors — for over two decades. Its eddy-current sensing principle, combined with the 3300 Series signal conditioning drivers, delivered the measurement accuracy and reliability that API 670 machinery protection standards demand.

Bently Nevada has since transitioned its product portfolio toward the 3500 Series and newer Orbit 60 platform. The 330104-00-06-05-11-05 probe, along with its companion drivers and extension cables, is no longer manufactured. Plants that built their machinery protection systems around the 3300 XL architecture now face a binary choice: source genuine spare probes from the secondary market, or undertake a full system replacement.

This is the operational logic behind maintaining a strategic spare inventory of the 330104-00-06-05-11-05. One probe on the shelf eliminates the risk of an unplanned shutdown on a machine that is otherwise fully functional and monitored.

How to extend your 3300 Series asset life by 5–10 years — a practical framework for plant management:

Plants that execute this framework consistently report 7–10 additional years of productive life from their 3300 Series machinery protection infrastructure — with total maintenance costs that are a fraction of a platform migration.

Condition & Reliability Assurance

Sourcing discontinued proximity probes from the secondary market carries inherent risk. DriveKNMS applies a structured 5-step qualification process to every 330104-00-06-05-11-05 unit before it is offered for sale.

1. Physical inspection. Full visual examination of probe tip, cable jacket, and connector body. Units with tip damage, jacket cracking, or connector pin deformation are rejected.
2. Connector pin integrity check. Each 11-pin connector is inspected for corrosion, bent pins, and contact resistance. Corroded contacts are a primary failure mode for probes stored in humid environments.
3. Gap voltage verification. Each probe is bench-tested with a compatible 3300 Series driver against a certified target material (AISI 4140 steel) to verify output voltage linearity across the specified gap range. Probes that fall outside the published sensitivity specification are rejected.
4. Cable continuity and insulation resistance test. Full cable length is tested for conductor continuity and insulation resistance. Degraded cable insulation — a common aging failure in probes stored beyond 10 years — is a disqualifying condition.
5. Firmware and label verification. Part number, date code, and revision markings are cross-referenced against Bently Nevada documentation to confirm authenticity and revision compatibility.

Key Features for System Maintenance

• Drop-in replacement. The 330104-00-06-05-11-05 installs directly into existing 3300 Series probe mounts. No mechanical modification, no driver reconfiguration, no setpoint adjustment required when replacing a like-for-like unit.
• No reprogramming. Unlike platform migrations that require monitor rack reconfiguration and setpoint re-entry, a probe swap is a maintenance task — not an engineering project. A qualified instrument technician can complete the replacement and gap verification in under two hours.
• Avoids engineering rework costs. Retaining the 3300 Series architecture eliminates the need for new loop drawings, updated P&IDs, revised cause-and-effect matrices, and management of change documentation that a platform migration would require.
• API 670 compliance maintained. Replacing with a genuine Bently Nevada 330104-00-06-05-11-05 preserves the original system's API 670 compliance status. Third-party probe substitutions may require re-validation of the entire measurement loop.

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

Q: Can you support multi-unit or repeat RFQ requests?
A: Yes. Send the model list, target quantity and destination so DRIVEKNMS can review sourcing options and quote the requirement as a project RFQ.

Can this probe be used with the Bently Nevada 3500 Series?
The 3300 XL 8mm probe family can be used with 3500 Series monitors when paired with the appropriate 3500/42 or 3500/44 monitor modules and compatible drivers. Confirm driver compatibility with your system documentation before installation.
