Bently Nevada 330904-00-05-70-01-05 Eddy Current Proximity Probe – NSv Series
When a critical rotating machine loses its shaft vibration monitoring capability, the consequences are immediate and severe: undetected rotor imbalance, bearing wear, or shaft misalignment can escalate within minutes into catastrophic mechanical failure, unplanned downtime, and six-figure repair costs. In high-stakes environments — power generation turbines, petrochemical compressors, marine propulsion systems — the absence of a reliable proximity probe is not a maintenance gap; it is an operational liability. The Bently Nevada 330904-00-05-70-01-05 NSv Proximity Probe is the precision sensing element that stands between normal operation and disaster.
The 330904-00-05-70-01-05 is a member of Bently Nevada’s NSv (Non-contacting vibration) Series — one of the most widely deployed eddy current proximity probe families in global industrial automation. Engineered to deliver sub-micron resolution in shaft radial vibration, axial position, and differential expansion measurement, this probe integrates seamlessly with the 3300 XL and NSv monitoring systems. Its 5 mm tip diameter, 70 mm cable extension, and 01-05 connector configuration make it the preferred choice for OEM turbomachinery builders and end-user maintenance teams operating under API 670 compliance requirements worldwide.

Frequently Asked Questions
Q: Is the 330904-00-05-70-01-05 a direct replacement for older Bently Nevada 7200 series probes?
A: The NSv series uses a different calibration curve than the 7200 series. Direct substitution requires verifying Proximitor compatibility. Contact our technical team for a compatibility assessment before ordering.
Q: Can this probe measure axial position as well as radial vibration?
A: Yes. When installed in a thrust position configuration with the appropriate Proximitor, the 330904-00-05-70-01-05 can measure axial shaft position and differential expansion in addition to radial vibration.
Q: What is the standard lead time for this part?
A: Lead time depends on current stock levels. Please submit an inquiry for a real-time availability check. In-stock units typically ship within 3–5 business days.
Q: Do you provide a warranty on this product?
A: Yes. We offer a 90-day warranty against manufacturing defects on all parts supplied. Terms are detailed in our quotation documentation.
Q: Can you supply the complete NSv transducer system (probe + extension + Proximitor)?
A: Yes. Konmask.com can source and supply complete matched transducer systems. Please specify your total cable length requirement when submitting your inquiry.
