Bently Nevada 330104-00-22-10-02-05 – Reverse‑Mount 8 mm Proximity Probe for Critical Machinery Vibration and Position

The Bently Nevada 330104-00-22-10-02-05 is part of the 3300 XL 8 mm proximity transducer family, designed for reverse‑mount installations where you need a flush, protected probe tip without external threading on the machine face. From my experience, this model is typically chosen for radial vibration, shaft position, and thrust measurements on compressors, turbines, large motors, and gearboxes—especially where a standard front‑mount probe is hard to secure long‑term. You might notice that it pairs with the 3300 XL Proximitor Sensor and a matching extension cable to form a complete, calibrated system with the familiar 200 mV/mil (≈7.87 mV/µm) scale factor.

Key Features

• Reverse‑mount 8 mm probe design – Protects the probe tip and simplifies mounting in tight or harsh locations, reducing accidental damage during maintenance.
• 3300 XL system compatibility – Works with 3300 XL Proximitor Sensors and extension cables for a fully calibrated eddy‑current measurement chain.
• Established scale factor – When used with the matching Proximitor, the system provides the standard 200 mV/mil output, making it easy to integrate with existing monitoring racks or PLC/DCS inputs.
• Industrial robustness – The 3300 XL series is known for reliable performance in oil film bearing machines and variable temperature environments.
• Suffix‑configured build – The 00‑22‑10‑02‑05 options set factory‑defined attributes such as integral cable length and fitting/boot options; it appears this model is tailored for common API‑style machinery layouts.

Technical Specifications

Application Fields

Typical use cases include:

• Radial vibration and shaft position on API 610/611 pumps, process compressors, and steam/gas turbines.
• Thrust position monitoring on large bearings when using the 8 mm system with matching Proximitor settings.
• Keyphasor‑style once‑per‑rev tracking on gear trains where mechanical access favors reverse mounting.
• Retrofitting older 3300 installations to the XL platform while keeping the 200 mV/mil standard for continuity.

Advantages & Value

• Reliability in harsh service – The 3300 XL lineage is proven on critical rotating assets, which, in many cases, translates to fewer nuisance trips and lower lifecycle cost.
• Compatibility – Drop‑in with 3300 XL Proximitor Sensors and monitors; keeps the standard scale factor your team already trusts.
• Flexible configuration – Suffix options define cable length and accessories, helping you hit the exact routing and panel distances you need.
• Procurement confidence – Standardized parts make spares planning simpler across multi‑site fleets; from my experience, that reduces downtime during outages.

Installation & Maintenance

• Mounting: Use the specified reverse‑mount hardware and a properly machined bore/counterbore. Maintain recommended probe‑to‑target gap; set the Proximitor bias near mid‑range (typically around −10 VDC) during commissioning.
• Cabinet & wiring: Place the Proximitor in a ventilated control cabinet; route probe/extension cables away from high‑EMI power lines; maintain correct cable lengths per Bently Nevada guidelines.
• Safety: De‑energize associated equipment, lockout/tagout, and verify hazardous area approvals for your exact suffix combination if the site is classified.
• Routine care: Periodically verify gap and scale factor, inspect cable strain relief/boots, clean the probe tip area if oil varnish builds up, and record baselines after outages.

Quality & Certifications

• Conformity: CE marking and RoHS compliance are typical for this family.
• Hazardous locations: ATEX/IECEx/CSA options exist on selected suffixes; the 00/22/10/02/05 combination should be confirmed for your site classification.
• Warranty: 365‑day warranty coverage as standard.

Related/Supporting Components

• 3300 XL Proximitor Sensor (8 mm system) – Required for drive and signal conditioning.
• 330130 Extension Cable – Standard extension cable used with 5 mm/8 mm 3300 XL probes.
• Mounting hardware and reverse‑mount adapters – Selected to match your machine bore and sealing method.

If you’re replacing a like‑for‑like probe, this exact suffix set keeps your calibration chain consistent. If you’re standardizing across assets, share your extension cable length and proximitor location—matching those details typically saves commissioning time and avoids scale mismatches.
