Bently Nevada 330905-01-08-10-01-00 Proximity Probe – NSv Series Eddy Current Sensor
When a critical rotating machine loses its vibration monitoring capability, the consequences are immediate and severe: undetected shaft imbalance, bearing wear, or rotor rub can escalate within minutes into catastrophic equipment failure, unplanned downtime, and six-figure repair costs. The proximity probe is the first line of defense—and without a properly functioning unit, your entire condition monitoring system is blind. The Bently Nevada 330905-01-08-10-01-00 NSv Proximity Probe restores that critical sensing capability, ensuring your machinery protection system operates with the precision it was designed for.
The 330905-01-08-10-01-00 is an 8mm eddy current proximity probe within Bently Nevada’s industry-leading NSv (Non-contacting vibration) Series. Engineered to integrate seamlessly with the 3300 XL and NSv monitoring systems, this probe is the global standard for shaft radial vibration, axial position, and differential expansion measurement in turbines, compressors, pumps, and generators. Bently Nevada—a Baker Hughes company—holds the dominant position in rotating machinery protection worldwide, and the NSv Series represents their latest generation of high-accuracy, long-life eddy current sensing technology.

Frequently Asked Questions
- Q: Is the 330905-01-08-10-01-00 a direct replacement for older 330905 series probes?
- A: In most cases, yes. The NSv series maintains backward compatibility with 3300 XL Proximitor sensors. However, always verify the Proximitor model and gap voltage settings before installation. Contact us for application-specific guidance.
- Q: What is the difference between the 330905 and 330730 probe series?
- A: The 330905 is an 8mm NSv probe optimized for the NSv Proximitor system, while the 330730 is a 5mm probe for the 3300 XL system. They are not interchangeable without changing the Proximitor sensor and recalibrating the system.
- Q: Can this probe be used in hazardous (Zone 1/Zone 2) areas?
- A: Yes, subject to the applicable ATEX/IECEx certification markings on the unit. Always verify the certification code matches your area classification before installation.
- Q: Do you supply the complete Bently Nevada 3500 system or individual modules?
- A: Both. Konmask.com supplies individual probes, Proximitor sensors, extension cables, and complete 3500 rack systems. Inquire with your full BOM for a consolidated quotation.
- Q: What is the typical lead time?
- A: In-stock units ship within 3–5 business days internationally. For items requiring sourcing, lead time is typically 2–4 weeks. Express options available for critical shutdowns.
