Bently Nevada 330104-00-16-05-02-00 – Proximitor Sensor for 3300 XL 8 mm Displacement & Vibration Monitoring

The Bently Nevada 330104-00-16-05-02-00 is part of the 3300 XL 8 mm proximity transducer system, designed for precise shaft displacement, radial vibration, and thrust position measurements on critical rotating assets. From my experience, it’s the go-to replacement when you want drop-in compatibility with existing 3300/3500 monitors without re-engineering your cabinet or wiring. You might notice that it typically delivers the familiar 200 mV/mil (7.87 mV/µm) output and stable linearity across the standard 80 mil range when paired with the correct 8 mm probe and extension cable.

Key Features

• 3300 XL 8 mm system compatibility: Designed to work with 8 mm probes and extension cables for consistent displacement and vibration readings.
• Standard scale factor: Typically 200 mV/mil (7.87 mV/µm), enabling easy cross-compatibility with existing monitor scaling.
• Stable linear range: Commonly supports up to 80 mils (≈2.0 mm) linear range when matched with the correct probe/cable set.
• Industrial temperature rating: Sensor electronics usually rated for cabinet environments found in turbomachinery applications.
• Robust eddy-current measurement: Proven technology for shaft vibration, position, and runout under harsh conditions (oil, heat, and electrical noise).
• Easy panel or DIN-rail mounting: Installs neatly inside existing protection panels with standard mounting hardware.

Technical Specifications

Application Fields

This model is commonly used on steam and gas turbines, centrifugal compressors, large pumps, gearboxes, fans, and generators. Typical tasks include:

• Radial vibration and shaft position for protection in API 670-style systems
• Thrust position monitoring on high-value turbomachinery
• Shaft runout and slow-roll checks during maintenance windows
• Condition monitoring data for reliability programs tied to 3500 rack systems

Advantages & Value for Procurement

• Form-fit-function compatibility: Simplifies replacements and spares stocking—no need to redesign the panel or re-scale monitors.
• Reliable measurement chain: When matched with 3300 XL probes and cables, it delivers consistent readings that maintenance teams trust.
• Lower lifecycle cost: Stable calibration reduces nuisance alarms and unplanned site work, which, in many cases, is where the real savings show up.
• Broad industry acceptance: Easier internal approvals thanks to widely recognized Bently Nevada standards.

Installation & Maintenance Tips

• Cabinet & environment: Mount the Proximitor in a clean, ventilated cabinet; maintain separation from high-voltage runs and VFD cables to reduce noise coupling.
• Grounding & shielding: Use the recommended grounding scheme and shield terminations; from my experience, this prevents most intermittent noise issues.
• Probe/cable matching: Ensure the probe and extension cable options match this sensor’s configuration; mismatched parts can alter sensitivity and linear range.
• Gap & linearity checks: Verify the mechanical gap and perform a slow-roll or runout check after installation, especially before commissioning protection setpoints.
• Routine care: Periodically inspect connectors and cable integrity; clean terminal areas and verify calibration during planned shutdowns.

Quality & Certifications

• CE and RoHS compliance; UL/cUL recognition is typically available for relevant assemblies
• 365-day warranty coverage as stated above
• Traceable sourcing and testing available on request

Related/Supporting Components

If you’re planning a full channel build or a like-for-like replacement, consider pairing with:

• 3300 XL 8 mm Proximity Probe (e.g., 330103 series)
• 330130 Extension Cable (length to match the installed probe distance)
• Bently Nevada 3500 monitoring modules for protection/condition monitoring

One thing I appreciate is how this model behaves predictably across different machines when the transducer chain is set up correctly. If you need a quick cross-check on option codes or cable lengths for 330104-00-16-05-02-00, share your installed-probe details and cabinet distance—we can validate the stack-up so the scale factor stays on-spec.
