Bently Nevada 330710-000-60-10-02-00 – 3300 XL 11 mm Proximity Probe for Machinery Protection

The Bently Nevada 330710-000-60-10-02-00 is a specific configuration of the 3300 XL 11 mm proximity probe, used with a matching extension cable and 3300 XL Proximitor sensor to measure shaft vibration and axial position. From my experience, the 11 mm tip is chosen when you need extra mechanical robustness and a wider linear range on heavy-duty assets—think steam or gas turbines, large compressors, gearboxes, and paper machine rolls. It’s the reliable, field-proven setup that maintenance teams tend to standardize on for continuous condition monitoring.

Key Features

• 11 mm probe tip – Extra mechanical robustness and a wider linear range for large-shaft machinery.
• Part of the 3300 XL system – Works with 3300 XL extension cables and Proximitor sensors for complete proximity transducer chains.
• Wide linear range – Typically up to 4 mm (≈160 mil), suitable for both dynamic vibration and DC shaft position (gap) measurement.
• Industry-standard scale factor – About 7.87 mV/µm (200 mV/mil) for easy integration with Bently Nevada monitors.
• High-temperature capability – Probe and cable assemblies are designed for hot, oily machine environments; the Proximitor sits in a cooler enclosure.
• Calibrated for AISI 4140 steel – Consistent, repeatable results on the most common target material; correction factors apply for others.
• System length flexibility – Typically available in 5 m or 9 m system lengths (probe + extension cable) to suit cabinet locations.
• Drop-in compatibility – In many cases, a like-for-like replacement on existing 3300/3500-based protection systems.

Technical Specifications

Application Fields

Typically specified for critical rotating equipment where continuous protection is non-negotiable:

• Steam/gas turbines, hydro units, and large motors
• Process compressors, pumps, and gearboxes
• Paper machines, centrifuges, and fans
• API 670-compliant vibration and axial position monitoring schemes

One thing I appreciate is how forgiving the 11 mm probe is in tough environments—oil splash, heat, and tight mounting clearances. A maintenance lead at a power plant told us they prefer this size on turbine bearings because it “just stays stable across outages,” which seems to be consistent with what many sites report.

Advantages & Value

• Reliability under heat and oil – Proven 3300 XL construction holds calibration and signal integrity in harsh conditions.
• Compatibility – Designed for 3300 XL Proximitor sensors and typically used with Bently Nevada monitoring systems (e.g., 3500 Series), reducing integration risk.
• Lifecycle savings – Drop-in replacements minimize downtime; consistent scale factors simplify spares and calibration.
• Technical support – Clear part-numbering helps match existing system lengths and thread types, which speeds up procurement.

Installation & Maintenance

• Mounting – Install the probe through a rigid, properly aligned bracket or bearing housing; lock with the jam nut and set the nominal gap to spec using feeler gauges.
• Cabling – Route the probe cable to the extension cable and then to the 3300 XL Proximitor; avoid sharp bends and high EMI sources; maintain proper shielding and grounding.
• Enclosure – Place the Proximitor in a ventilated, dry control cabinet (IP-rated) within its temperature limits; provide clean power (−24 VDC typical).
• Safety – Follow lockout/tagout; confirm hazardous area approvals for the exact configuration before installation.
• Routine checks – Periodically verify probe gap, clean the probe tip if fouled, confirm tight mechanical mounting, and validate the monitor’s reading against a known displacement. Firmware updates apply to the monitoring rack, not the probe.
• Calibration – System is factory-calibrated to AISI 4140 steel; if target material differs, apply the correct material factor in the monitoring system.

Quality & Certifications

• CE marking and RoHS compliance in most configurations
• CSA/ATEX/IECEx hazardous area approvals available on selected setups (verify against the exact part code)
• Manufacturer-grade build standards for API 670 applications
• Warranty: 365 days
