Bently Nevada 330106-05-30-10-02-05 Proximity Probe – Non‑contact shaft vibration and displacement sensing for critical rotating machinery

The Bently Nevada 330106-05-30-10-02-05 is a 3300 XL-series proximity probe assembly used to monitor shaft vibration, axial position, and rotor-to-stator clearance on turbines, compressors, pumps, and similar assets. It’s built for harsh industrial environments and works with a matching 3300 XL Proximitor Sensor and extension cable to provide reliable eddy‑current measurements. From my experience, this combination is the default choice in many API 670-compliant installations when you need stable readings across temperature swings and tight mounting spaces.

Company’s Order Placement Process and Guarantees

• Express options: FedEx, UPS, DHL

Key Features

• Non-contact eddy-current sensing – Measures shaft vibration and displacement without mechanical loading, ideal for high-speed rotors.
• 3300 XL system compatibility – Designed to operate with the corresponding 3300 XL Proximitor Sensor and extension cable for a calibrated chain.
• Robust probe construction – Typically rated for elevated temperatures and oil-rich environments commonly found in bearing housings and seal areas.
• Threaded mounting – Simplifies installation through holders or tapped holes; allows fine adjustment of probe gap.
• Coded configuration – You might notice “-05” in the code; in many cases it denotes a 5 m probe lead, while other digits define thread, tip, connector, or armor options.
• Stable gap voltage – When paired with the proper Proximitor, you get a steady -10 V to -2 V gap voltage window and a dynamic voltage proportional to motion.
• API 670 condition monitoring workflows – Works seamlessly with Bently Nevada monitors and historians for trip, trending, and protection logic.

Technical Specifications

Application Fields

Typically deployed on steam and gas turbines, centrifugal compressors, gearboxes, motors, fans, and critical pumps. Use it where non-contact vibration, shaft radial position, or thrust measurements feed into protection relays or condition monitoring systems. One thing I appreciate is how it holds calibration even in oil splash zones, which reduces drift in long-term trending.

Advantages & Value

• Reliability under heat and oil – The 3300 XL design is known for stable output across temperature and contamination, which cuts nuisance alarms.
• Compatibility and scalability – Works with mainstream Bently Nevada racks and distributed systems; easy to add channels as assets grow.
• Lower lifecycle cost – Durable probe and cabling typically mean fewer shutdowns for replacement, saving labor and production time.
• Technical support continuity – Widely used in API 670 environments; documentation and field know-how are straightforward to source.

Installation & Maintenance

• Mounting – Install in a rigid probe holder or tapped hole; ensure the tip faces a clean, conductive target surface. Maintain clearance and avoid probe bending during routing.
• Cabinet & wiring – Place the Proximitor in a ventilated cabinet; route probe and extension cables away from high-voltage lines and VFDs. Use proper grounding and shielding.
• Gap set – With the system powered, adjust probe until the monitor indicates a mid-range gap voltage (commonly around -8 to -10 V to -2 V window, depending on the setup).
• Safety – De-energize associated equipment before mechanical adjustments. In hazardous areas, ensure the exact probe option code meets the zone requirements.
• Routine care – Periodically inspect connectors, clean the probe tip if fouled, verify tightness of mounts, and review calibration in your monitoring software after outages.

Simulated feedback: “We swapped two older probes on a hot-end turbine bearing with this model code, kept the existing Proximitor and cable spec, and the noise floor dropped immediately—trending stabilized within a day.”

Quality & Certifications

• Typically conforms to CE requirements; RoHS-compliant materials are common in the 3300 XL family
• Manufactured under ISO 9001-quality systems
• Hazardous area approvals (e.g., ATEX/IECEx) may be available depending on option codes; verify against the product nameplate
• Manufacturer’s warranty practices apply; our supplied units carry a 365-day warranty as stated above

Notes on Configuration Code

The sequence “-05-30-10-02-05” defines specifics such as cable length, thread type, tip style, connector orientation, and armor or protection options. “-05” is commonly a 5 m probe lead. If you share your existing part code or machine drawing, we can double-check thread and connector options to ensure drop-in compatibility with your installed Proximitor and extension cable.
