Bently Nevada 330104-00-06-10-02-00 Proximity Probe – Cost‑Effective 8 mm Eddy-Current Sensing for Budget-Conscious Projects

If you’re standardizing on Bently Nevada’s 3300 XL platform, the 330104-00-06-10-02-00 hits a sweet spot: true OEM performance with the familiar 8 mm tip, yet priced to keep maintenance programs on track. One thing I appreciate is how it drops straight into existing 3300/3500 monitoring systems when paired with the proper Proximitor sensor—no rewiring gymnastics, no guessing the scale factor.

Company’s Order Placement Process and Guarantees

Key Features

• 8 mm 3300 XL probe head – General‑purpose tip size for shaft vibration and axial position on medium to large machinery.
• Designed for 3300/3500 systems – Delivers the standard 200 mV/mil (≈7.87 mV/µm) output when used with a compatible 3300 XL Proximitor sensor.
• Robust, factory‑terminated integral cable – The -06 variant is typically selected for mid‑length runs, helping reduce slack and junction points.
• High temperature capability – Probe and cable assemblies are engineered for elevated temperatures found near bearings and seals.
• API 670‑style measurement approach – In many cases meets plant specifications for critical machinery protection when used with correct drivers and monitors.
• Shielded for electrical noise – Stable readings around VFDs and large motors, which seems to be where cheaper probes struggle.
• Drop‑in mechanical fit – Threaded body works with standard Bently Nevada probe brackets and mounting hardware.

Application Fields

From my experience, this probe ends up on rotating assets where reliability beats features creep: steam turbines, gas compressors, process pumps, blowers, fans, and large electric motors. You might notice the 8 mm tip gives you forgiving installation tolerances on thicker bearing housings and pedestal mounts. Typical uses include:

• Shaft radial vibration on journal-bearing machines
• Thrust position on compressors and turbines (with appropriate axial mounting)
• Runout and rotor-to-stator clearance checks during startup commissioning
• Condition monitoring upgrades where a direct Bently Nevada replacement is expected

Advantages & Value

• Budget‑friendly without surprises – In many cases, it’s a drop‑in replacement that reuses your existing Proximitor and wiring.
• Reduced downtime risk – Standard 3300 XL behavior means your 3500 rack thresholds and API 670 alarm settings stay valid.
• Compatibility assurance – Works with Bently Nevada extension cables and mounting hardware, avoiding one‑off adapters.
• Supported through lifecycle – We stock common variants and provide configuration checks before shipment; field notes help you avoid the usual gap/length pitfalls.

Quick feedback from a maintenance lead at a gas compressor station: “We chose the -06 variant to tidy cable runs inside the bearing housing. No retraining, readings matched our previous baselines within a few microns.”

Installation & Maintenance

• Environment – Mount the probe in a rigid bracket/sleeve; keep cable away from hot exhausts and moving parts. Maintain gentle bends (large radius) and secure at intervals.
• Wiring – Route to the 3300 XL Proximitor in a protected conduit where possible. Good practice is to separate from high‑power cables to minimize EMI.
• Gap setting – Set mechanical gap per machine spec (typically mid‑range of the Proximitor’s linear range). Verify zero/span at the monitor after warm‑up.
• Safety – Lock‑out/Tag‑out before touching any proximity hardware. Use ESD precautions when connecting/disconnecting coax.
• Routine care – Inspect tip face for debris during outages; clean gently with lint‑free swab. Confirm tightness of the locknut, check cable strain relief, and review trending for drift. Firmware updates apply to the monitor, not the passive probe, but keeping 3500 rack firmware current is wise.

Quality & Certifications

• Typically CE compliant and RoHS conformant for industrial use
• Manufactured under ISO 9001 quality systems (typical for Bently Nevada production)
• Commonly applied in API 670 compliant protection systems when used with matching components
• Seller warranty: 365 days; manufacturer’s standard policy applies when purchased new

Recommended Supporting Components

• Bently Nevada 3300 XL Proximitor Sensor (8 mm) – Required driver that provides the calibrated 200 mV/mil output to your monitor.
• Bently Nevada 330130 Extension Cable – Select to achieve standard system lengths (typically 5 m / 7 m / 9 m total) matching your monitor configuration.
• Probe Brackets/Sleeves – Use standard Bently Nevada hardware to ensure stable mounting and repeatable gap.

If you want us to double‑check the exact thread type and total system length for 330104-00-06-10-02-00 against your existing racks, share your current Proximitor and extension cable part numbers—we typically confirm compatibility in a few minutes and prevent mix‑and‑match headaches.
