⚠ Note: Extension cables are system-matched. Mixing cable lengths or series without recalibration will affect gap voltage and measurement accuracy.
Why Choose the Original Model
- System-Calibrated: The 330903-00-09-10-02-05/CN is factory-matched to the 3300 NSv proximitor for zero-adjustment installation.
- Signal Integrity: Precision 50 Ω impedance and gold-plated connectors eliminate signal loss across the full 9 m run.
- Harsh-Environment Rated: PTFE jacket and stainless armoring resist oil, steam, and vibration in turbomachinery bays.
- Compliance Ready: /CN suffix ensures conformance with Chinese industrial standards — no additional certification required for domestic installations.
- Plug-and-Play: No field calibration needed when replacing like-for-like within the 3300 NSv system.
Typical Applications
- Steam and gas turbine shaft vibration monitoring
- Centrifugal compressor radial and axial displacement measurement
- Pump and motor bearing condition monitoring
- Gearbox and expander rotor dynamics surveillance
- Petrochemical, power generation, and LNG plant machinery protection systems
System Compatibility
- Proximitor/Driver: Bently Nevada 330180-X1-05 / 330180-X1-CN series (3300 NSv)
- Probe: Bently Nevada 330900 series proximity probes (8 mm)
- Monitor: 3300/16 Dual Voting, 3300/20 Radial Vibration, 3300/25 Thrust Position
- System Platform: System 1 Condition Monitoring Software (compatible)
- Not Compatible With: 3300 XL proximitors without re-verification; 7200 series probes
Selection Guide
Use the following decision flow to confirm the correct part number for your application:
- Identify your proximitor model — confirm it is a 330180 (3300 NSv) series unit.
- Measure the required cable run — distance from probe tip to proximitor input. Select the cable length segment accordingly (e.g., “-09-” = 9 m).
- Check the environment rating — standard PTFE jacket suffices for most applications; select 330905 series for sustained temperatures above 105 °C.
- Confirm the market suffix — /CN for China-compliance installations; omit suffix for standard international units.
- Verify connector orientation — the “-02-05” suffix encodes connector configuration; do not substitute without cross-referencing the wiring diagram.

Replacement & Compatibility FAQ
Q: Can I use a 330903-00-05-10-02-05 (5 m) cable in place of the 9 m unit?
A: Only if the physical cable run is ≤5 m. Coiling excess cable is not recommended — it introduces inductance that affects gap voltage readings.
Q: Is the /CN variant electrically identical to the standard version?
A: Yes. The /CN suffix denotes compliance documentation only; electrical and mechanical specifications are identical.
Q: Can this cable be used with a 3300 XL proximitor?
A: Not directly. The 3300 NSv and 3300 XL systems use different scale factors. Cross-series use requires full system recalibration and is not recommended without Bently Nevada engineering approval.
Q: What is the lead time if out of stock?
A: Typical lead time for restocked units is 2–4 weeks. Contact us to join the priority notification list.
Q: Do you provide a Certificate of Conformance?
A: Yes, available upon request at no additional charge.
