Bently Nevada 330905-00-02-10-02-05/CN Proximity Probe – 3300 NSv Series
When a critical rotating machine loses its vibration monitoring capability, the consequences are immediate and severe: undetected shaft displacement, catastrophic bearing failure, unplanned shutdowns, and millions in lost production. In high-stakes environments — gas turbines, steam turbines, centrifugal compressors, and large pumps — the proximity probe is not optional equipment. It is the first line of defense between normal operation and mechanical disaster. The Bently Nevada 330905-00-02-10-02-05/CN is the precision eddy-current sensor that keeps that defense intact.
Within the renowned Bently Nevada 3300 NSv (Non-contacting Vibration) Series, the 330905-00-02-10-02-05/CN occupies a well-defined technical position: a standard-range, 5-meter extension cable configuration designed for installations where the driver and monitor are separated by moderate distances. The 3300 NSv platform is one of the most widely deployed proximity probe systems in global industrial automation, trusted by OEMs and end-users across petrochemical, power generation, and heavy manufacturing sectors. Its eddy-current operating principle delivers non-contact, wear-free measurement of radial shaft vibration, axial position, and differential expansion — parameters that are mandatory inputs for API 670-compliant machinery protection systems.

- Marine & Offshore: Propulsion turbines, offshore platform compressors
- General Heavy Industry: Any rotating machinery requiring API 670-compliant vibration monitoring
System Integration & Compatible Parts
The 330905-00-02-10-02-05/CN proximity probe is designed to operate as part of a complete Bently Nevada 3300 NSv measurement chain. Typical compatible components include:
- Proximitor Drivers: Bently Nevada 3300 XL 8mm Proximitor (e.g., 330180 series)
- Monitors: Bently Nevada 3500 Series Machinery Protection System (3500/40M, 3500/42M, 3500/45, 3500/46M)
- Junction Boxes: Bently Nevada field junction boxes for multi-probe installations
- Mounting Hardware: M10 probe holders, lock nuts, and bracket assemblies
Always verify the complete measurement chain (probe + extension cable + Proximitor driver) is matched to the same series and calibration standard before installation.

Frequently Asked Questions
Q: What does the “/CN” suffix mean on 330905-00-02-10-02-05/CN?
A: The “/CN” designation indicates a specific connector or cable termination variant within the 3300 NSv probe family. It is important to match this suffix to your existing Proximitor driver and installation to ensure correct signal output and mechanical fit.
Q: Is this probe compatible with the Bently Nevada 3500 Series monitors?
A: Yes, when used with the appropriate 3300 NSv Proximitor driver (e.g., 330180 series), the output signal is fully compatible with Bently Nevada 3500 Series monitors. The complete measurement chain must be matched.
Q: Can I use this probe on non-steel shafts?
A: The 3300 NSv probes are calibrated for specific target materials. Using the probe on a different target material (e.g., titanium or aluminum) will require recalibration of the Proximitor driver. Contact us for calibration guidance.
Q: What is the minimum order quantity?
A: We supply single units for emergency replacements as well as bulk quantities for MRO stocking programs. Please submit your RFQ with your required quantity.
Q: Do you provide export documentation for international shipments?
A: Yes. We provide commercial invoice, packing list, certificate of conformance, and can assist with any additional documentation required for customs clearance in your country.
Q: How long does shipping take?
A: Shipping timelines depend on destination and logistics mode. Express air freight to most destinations takes 3–7 business days. We will confirm lead time and shipping options in your quotation.
