Vibration Monitoring Solution – Bently Nevada 330905-00-24-10-02-00 | 3300 NSv Series
Where This Product Is Used
The Bently Nevada 330905-00-24-10-02-00 proximity probe is a core sensing element in continuous machinery protection systems across heavy industry. Engineers specify this model in the following environments:
- Steam & Gas Turbines – Radial shaft vibration and axial position monitoring on high-speed rotating shafts in power generation plants.
- Centrifugal Compressors – Real-time rotor orbit tracking in petrochemical and LNG compression trains to detect instability before failure.
- Pumps & Blowers – Continuous displacement measurement on critical process pumps in refineries and water treatment facilities.
- Gearboxes – Gear mesh frequency analysis and shaft eccentricity detection in paper mills and steel rolling lines.
- Marine Propulsion Systems – Shaft monitoring on vessel main engines and auxiliary turbines requiring compact, corrosion-resistant sensors.
- Nuclear & Thermal Power Plants – Safety-critical vibration loops where API 670 compliance is mandatory.

Why Engineers Specify This Model
- 24-Inch Extension Cable – Ideal for installations where the Proximitor® driver must be mounted away from the bearing housing, reducing thermal exposure to electronics.
- NSv (Non-Standard Voltage) Design – Optimized scale factor for use with the 3300 NSv Proximitor®, ensuring accurate gap-to-voltage conversion without field recalibration.
- Armored Cable Construction – Stainless steel armor protects signal integrity in high-vibration, high-temperature environments.
- Drop-in Replacement – Fully interchangeable with existing 3300 series installations; no driver reconfiguration required.
- API 670 Ready – Meets the measurement chain requirements for machinery protection systems per API Standard 670 (5th Edition).
- Proven Field Reliability – Bently Nevada proximity systems are the de facto standard in turbomachinery protection globally, with decades of installed base.

Application-Specific FAQ
Q: Can this probe be used with a 3300 XL Proximitor® instead of the NSv version?
A: No. The NSv probe is calibrated for the NSv Proximitor® scale factor. Using it with a standard 3300 XL driver will result in measurement error. Always match probe and driver series.
Q: What is the maximum shaft speed this probe can monitor?
A: Eddy-current probes have no mechanical speed limit. The upper frequency limit is determined by the Proximitor® driver bandwidth, typically flat to 10 kHz for the 3300 series — suitable for shafts up to 600,000 RPM in principle.
Q: Is the 24-inch extension cable length the total system cable, or just the extension?
A: The 24-inch (610 mm) figure refers to the integral extension cable on this probe assembly. Total system cable length must fall within the Proximitor® driver’s specified range — consult the 3300 NSv Proximitor® datasheet for exact limits.
Q: Can this probe be installed in a hazardous area (ATEX Zone 1)?
A: Yes, with an appropriate certified Zener barrier or galvanic isolator in the signal loop. The probe itself is passive; the system certification depends on the complete measurement chain configuration.
Q: Do you provide calibration certificates?
A: Calibration certificates and OEM test documentation can be requested at the time of order. Contact us before purchase if this is a project requirement.
