Bently Nevada 330910-00-04-10-02-00 – Eddy Current Proximity Probe | 3300 NSv Platform
Engineering Background: The Bently Nevada 3300 NSv Series represents the industry benchmark for non-contacting eddy current measurement in rotating machinery protection systems. Engineered to API 670 standards, this platform has been deployed across gas turbines, steam turbines, compressors, and pumps in critical process industries worldwide for over three decades.
Product Positioning: The 330910-00-04-10-02-00 is a 5 mm diameter proximity probe designed for shaft radial vibration, axial position (thrust), and differential expansion measurement. It integrates seamlessly with the 3300 NSv signal conditioning system, delivering high-resolution displacement data to plant DCS, SIS, and condition monitoring platforms.

System Architecture & Signal Flow
The 330910-00-04-10-02-00 probe forms the sensing element of a three-component measurement chain:
- Proximity Probe (330910-00-04-10-02-00) → generates eddy current field at target surface
- Extension Cable (330130 / 330180 series) → transmits RF signal with minimal loss over distances up to 9 m total
- NSv Proximitor Module (3300/16-xx-xx-xx) → demodulates signal, outputs –24 VDC bias and 7.87 V/mm displacement voltage to monitor rack or DCS analog input
Total system gap voltage at mid-range: approximately –10.5 VDC. Monitor rack alarm setpoints are configured per API 670 alert/danger thresholds.

Technical FAQ
Q: Is the 330910-00-04-10-02-00 compatible with the 3300 XL Proximitor?
A: Yes. The 3300 NSv probe is backward-compatible with 3300 XL 5 mm Proximitor modules. Verify gap voltage and sensitivity settings before commissioning.
Q: What is the maximum total cable length for this probe system?
A: The combined probe integral cable + extension cable must not exceed 9.0 m (29.5 ft) to maintain specified sensitivity and linearity.
Q: Can this probe measure non-ferrous targets (aluminum, titanium)?
A: Standard calibration is for AISI 4140 steel. Non-ferrous target applications require a target-specific calibration factor; contact our engineering team for guidance.
Q: Do you provide ATEX/IECEx certified units?
A: Intrinsically safe configurations are available. Please specify hazardous area classification (Zone 0/1/2, Gas Group, Temperature Class) when ordering.
Q: What documentation is included with shipment?
A: Standard shipment includes inspection report and packing list. Calibration certificate, material certificate (CoC), and original Bently Nevada datasheet available on request.
