Compatible Replacement & Equivalent Models
The following models are dimensionally and electrically compatible with the 330130-080-03-CN in most 3300 Series installations. Always verify total system cable length (probe + extension) against your Proximitor calibration range before substitution.
| Part Number | Length | Notes |
|---|---|---|
| 330130-080-03-CN | 8 m | OEM original — this listing |
| 330130-045-03-CN | 4.5 m | Shorter run; same connector family |
| 330130-085-03-CN | 8.5 m | Slight length variant; verify gap voltage |
| 330130-080-03-00 | 8 m | Non-CN suffix; confirm regional spec |
| 330130-080-02-CN | 8 m | Different jacket; check temperature rating |
| 3300 XL 8mm Probe Kit | System | Full probe + cable + Proximitor bundle |
⚠ Note: Total probe + extension cable length must match the Proximitor calibration (typically 5 m or 9 m system). Mixing lengths without recalibration will cause measurement error.
Why Choose the Original Model
- Factory-calibrated impedance — matched to 3300 Series Proximitor for zero-drift signal transmission
- Armored jacket — resists mechanical damage, oil, and chemical exposure in turbomachinery bays
- OEM connector geometry — plug-and-play replacement with no re-termination required
- Traceable documentation — Konmask supplies with CoC and test report on request
- Long-term availability — stocked for MRO continuity even on legacy 3300 Series installations
Typical Applications
- Steam and gas turbine shaft radial vibration monitoring
- Compressor rotor position and axial thrust measurement
- Pump and motor bearing proximity sensing
- Gearbox and expander machinery protection systems
- Petrochemical, LNG, power generation, and refinery rotating equipment
System Compatibility
The 330130-080-03-CN is designed for use within the Bently Nevada 3300 Series eddy-current measurement chain:
- Probe: 3300 XL 8mm or 11mm eddy-current probe (e.g., 330101-xx, 330103-xx)
- Extension Cable: 330130-080-03-CN (this unit)
- Proximitor Monitor: 3300/16 or 3300/20 series rack-mount monitors
- System: System 1 / System 1 Evolution condition monitoring platform
Verify that the combined probe + extension cable length matches the Proximitor’s calibrated range (5 m or 9 m total system).
Selection Guide
Use the following criteria to confirm the correct extension cable for your application:
- Probe model — confirm 8mm or 11mm probe family (affects connector type)
- Required cable run — measure actual distance from probe to junction box; select cable length accordingly
- Total system length — probe cable + extension must equal 5 m or 9 m for standard Proximitor calibration
- Environment rating — confirm temperature range and chemical exposure; select armored (-03) or standard jacket
- Suffix code — CN = China/Asia regional spec; 00 = standard global; verify with your Bently Nevada documentation

Replacement & Compatibility FAQ
Q: Can I use a 330130-080-03-CN to replace a 330130-080-03-00?
A: In most cases yes — the CN suffix denotes a regional specification variant. Verify connector type and jacket rating match your installation requirements.
Q: What happens if my total cable length doesn’t match the Proximitor calibration?
A: The Proximitor output will be offset, causing incorrect gap voltage readings. Always match total system length (probe + extension) to the calibrated value, or recalibrate the Proximitor after changing cable length.
Q: Is this cable compatible with 3500 Series monitors?
A: No. The 3300 and 3500 Series use different probe and cable systems. For 3500 Series, consult Bently Nevada 3500/42 or 3500/46 documentation for the correct cable part numbers.
Q: Do you supply the full 3300 Series probe kit?
A: Yes. Konmask stocks probes, extension cables, and Proximitor monitors across the 3300 Series. Contact us for a complete system quote.
Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. For out-of-stock items, typical lead time is 2–4 weeks. Contact us for current availability.
