Description
The Bently Nevada 330709-000-070-10-02-00 is a 3300 NSv proximity probe designed for tight mechanical clearances and small target areas where standard 8mm probes cannot fit. It operates primarily on centrifugal compressors, small pumps, and fluid-film bearings, providing high-precision dynamic vibration and static displacement measurements.

On a recent overhaul of a high-speed turbocharger, we ran into an issue where an installer assumed this 5mm NSv probe could use a standard 3300 XL 5mm Proximitor sensor. Well, technically the threads and connectors match perfectly, but the NSv series is specifically calibrated for smaller target diameters and tighter side-clearance windows. Pairing this probe with a standard XL-series sensor alters the eddy-current field geometry, completely ruining your output voltage linearity. Honestly, verify that your sensor part number matches the 330980 NSv series designation before locking down the jam nuts.
Global Logistics, Customs, and Incoterms Compliance
Shipping precision monitoring hardware across international borders requires rigorous trade documentation to prevent customs delays.
HS Classification and Export Control Information
This hardware falls under Harmonized System Code 9031.80.80 (Other measuring or checking instruments, appliances, and machines). Because these components monitor high-performance turbomachinery, some destination ports require an explicit declaration of the end-user facility to clear security verification logs. We ensure all compliance forms and country-of-origin data are cleanly formatted to minimize border clearance times.
Incoterms 2020 Framework
- FCA (Free Carrier): Highly efficient if your corporate forwarder handles routine consolidation from our international fulfillment hubs.
- DAP (Delivered at Place): We oversee transit directly to your plant site via priority express courier (DHL or FedEx), which is the standard choice for emergency forced-outage remediation.
Procurement FAQ
- What does the “-02” connector option represent?
The -02 designation specifies standard miniature coaxial connectors with click-lock mechanisms, shipped without connector protectors.
- Can this probe handle continuous immersion in synthetic lubricating oils?
Yes, the probe tip and case are sealed against typical industrial fluids, including hydrocarbon-based and synthetic lubricants, within its rated operating temperature range.
- How do I adjust the mechanical gap during installation?
Don’t underestimate this step: use a digital voltmeter connected to the Proximitor’s “OUT” and “COM” terminals to monitor the DC gap voltage while threading the probe into the bracket. For a standard calibration loop, aim for a baseline of −10.0 V DC at the center of the linear range before tightening the locknuts.
