Bently Nevada 330904-00-10-05-01-BR Proximity Probe – 3300 NSv Series
When a critical rotating machine — a gas turbine, steam turbine, or high-speed compressor — loses its shaft vibration monitoring capability, the consequences are immediate and severe. Without a functioning proximity probe, operators are blind to rotor displacement, bearing wear, and impending mechanical failure. Unplanned shutdowns, catastrophic equipment damage, and significant safety risks follow. The Bently Nevada 330904-00-10-05-01-BR proximity probe is the precision sensing element that keeps these machines running safely and continuously.
Within the renowned Bently Nevada 3300 NSv (Non-contacting Vibration) Series, the 330904-00-10-05-01-BR occupies a well-defined technical position: a standard-range, 5 mm tip diameter eddy current probe with a 1-meter (BR) integral cable, designed for direct integration with 3300 XL series proximitor/oscillator modules. This series is the global benchmark for machinery protection systems in oil & gas, power generation, and petrochemical industries, trusted by plant engineers across more than 100 countries.

Key Features & Benefits
- Non-contacting measurement: Zero mechanical wear on the probe or shaft — continuous operation without degradation.
- High-frequency response: Accurately captures shaft vibration, eccentricity, and axial position at high rotational speeds.
- Integral cable design: The 1 m BR cable eliminates field-assembly errors and ensures consistent signal integrity from probe tip to proximitor.
- Rugged construction: Stainless steel housing withstands harsh industrial environments including oil mist, high humidity, and elevated temperatures.
- Direct system compatibility: Plug-and-play replacement within existing Bently Nevada 3300 XL machinery protection systems — no recalibration of the system required when replacing like-for-like.
- Proven reliability: The 3300 NSv series has decades of field-proven performance in the most demanding rotating machinery applications worldwide.
Industry & Equipment Applications
- Oil & Gas: Gas turbines, centrifugal compressors, pipeline pumps, LNG trains
- Power Generation: Steam turbines, gas turbines, hydro generators, turbo-generators
- Petrochemical & Refining: Reactor charge pumps, cracked gas compressors, process compressors
- Marine & Offshore: Propulsion turbines, offshore platform rotating equipment
- General Industrial: High-speed fans, blowers, gearboxes with journal bearings
Typical measurement parameters: radial shaft vibration, shaft absolute vibration, differential expansion, eccentricity, and axial position (thrust).
System Integration & Compatible Parts
The 330904-00-10-05-01-BR is designed to operate as part of a complete Bently Nevada 3300 XL proximity measurement chain. Key compatible components include:
- Proximitor/Oscillator: 3300 XL 8mm Proximitor (e.g., 330180-X1-05)
- Extension Cable: 330130-series (to extend total cable length to 5 m or 9 m system)
- Rack/Monitor: 3500 Series Machinery Protection System (3500/40M, 3500/42M, 3500/45)
- Mounting Hardware: Standard Bently Nevada probe holder and lock nut assemblies
Always verify total system cable length (probe + extension) matches the proximitor calibration to maintain measurement accuracy.

Frequently Asked Questions
- Q: Is the 330904-00-10-05-01-BR a new or surplus part?
- A: Availability varies. Please submit an inquiry and we will confirm the exact condition and source of the stock available at the time of your order.
- Q: Can this probe be used with a 3500 Series monitor directly?
- A: The probe itself connects to a 3300 XL Proximitor module, which then interfaces with the 3500 Series monitor. The probe does not connect directly to the 3500 rack without the proximitor in the measurement chain.
- Q: What does “BR” mean in the part number?
- A: “BR” designates the cable type — in this case, a Belden-type integral cable. This affects cable flexibility and temperature rating. Ensure your replacement matches the original cable designation for like-for-like replacement.
- Q: Do you provide calibration certificates?
- A: Factory calibration is performed by Bently Nevada at the system level (probe + extension + proximitor as a matched set). We can provide available documentation; however, for safety-critical installations, we recommend system-level calibration verification after installation.
- Q: What is the lead time for this part?
- A: Lead time depends on current stock levels. In-stock items typically ship within 3–5 business days. For out-of-stock items, sourcing lead time is typically 2–6 weeks. Contact us for real-time availability.
