Compatible Replacement & Equivalent Models
When the exact part is unavailable or a cost-effective alternative is required, the following models are commonly evaluated as functional equivalents. Always verify gap voltage, sensitivity, and cable length before substitution.
- 330930-045-04-05 — Same series, alternate connector suffix; verify driver compatibility
- 330930-080-04-CN — Extended 8.0 m cable variant; same driver and sensitivity
- 330180-X1-CN — 3300 XL 8 mm standard probe; shorter linear range, lower cost
- 330101-00-04-10-02-CN — 3300 XL 5 mm probe system; suitable for tighter clearance installations
- Emerson CSI 6500 Proximity Probe — Third-party compatible; requires sensitivity calibration
- Metrix ST5484E — Eddy-current proximity transducer; API 670 compliant alternative
- Wilcoxon Research PC420 — Proximity probe system; confirm output scaling before use
Note: Konmask.com recommends using OEM Bently Nevada parts for safety-critical machinery. Third-party equivalents should be validated by a qualified instrumentation engineer.

Selection Guide
Use the table below to identify the correct 330930 variant for your installation:
- Cable length suffix: -045 = 4.5 m | -080 = 8.0 m | -120 = 12.0 m
- Driver suffix: -04 = standard NSv driver (7.87 V/mm)
- Connector suffix: -CN = standard coaxial | -05 = alternate connector
- Target material: Standard calibration for AISI 4140; specify non-standard alloy at order time
- Hazardous area: Confirm ATEX/IECEx zone rating if installation is in classified area
- Gap voltage: Verify monitor card input range matches probe output (-24 VDC nominal center)

Replacement & Compatibility FAQ
Q: Can I replace only the probe without replacing the driver?
A: Not recommended. The 3300 XL NSv system is factory-matched. Mixing components from different serial batches may affect calibration accuracy. Always replace as a complete system.
Q: Is the 330930-045-04-CN compatible with the Bently Nevada 3500/40M monitor?
A: Yes. The 3500/40M Proximitor I/O module is fully compatible with the 3300 XL NSv system at standard -24 VDC bias and 7.87 V/mm sensitivity.
Q: What is the difference between the -CN and -05 connector suffix?
A: The -CN suffix denotes the standard coaxial connector used in most installations. The -05 suffix is an alternate connector configuration. Verify your existing cable termination before ordering.
Q: Can third-party proximity probes replace this unit on API 670 systems?
A: Third-party probes may be used if they meet API 670 Annex D requirements and are validated against the installed monitor. Konmask recommends OEM parts for safety-critical applications.
Q: Do you provide calibration certificates?
A: Yes. Calibration certificates are available upon request. Please specify at time of order.
