Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or equivalents for the 330930-65-03-05. Always verify electrical and mechanical compatibility before substitution:
- Bently Nevada 330930-65-00-05 — Same probe/driver length, no extension cable; suitable when cable routing differs
- Bently Nevada 330930-65-05-05 — 5 m extension cable variant; drop-in replacement where longer cable is acceptable
- Bently Nevada 330905-02-12-05-02 — 3300 XL 8 mm standard probe system; compatible with same 3300 monitors
- Epro PR6423/010-040 — Third-party eddy-current transducer; requires sensitivity and gap verification
- Metrix ST5484E — Alternative proximity system; confirm monitor input compatibility
Note: Konmask.com recommends using original Bently Nevada components for safety-critical applications. Contact our team for cross-reference validation.
Why Choose the Original Model
- Certified Accuracy: Factory-calibrated to ±1% linearity — critical for API 670-compliant machinery protection systems
- System Integrity: Designed and tested as a matched probe/extension/driver system; mixing components from different manufacturers can introduce measurement errors
- Long-Term Support: Bently Nevada 3300 XL NSv systems are widely deployed; spare parts and technical support remain available
- Traceability: Original parts carry full manufacturer traceability, essential for regulated industries (oil & gas, power generation, petrochemical)
Typical Applications
- Radial vibration monitoring on steam turbines, gas turbines, and compressors
- Axial position (thrust) measurement on rotating shafts
- Differential expansion monitoring in power plant turbines
- Speed and phase reference measurement (Keyphasor® applications)
- Machinery protection systems per API 670 standard
System Compatibility
The 330930-65-03-05 is designed to operate within the Bently Nevada 3300 XL monitoring system and is compatible with the following monitors and racks:
- Bently Nevada 3300/16 Dual Vibration Monitor
- Bently Nevada 3300/20 Radial Vibration Monitor
- Bently Nevada 3500/42 Proximitor®/Seismic Monitor
- Bently Nevada 3500/40M Proximitor®/Seismic Monitor
- System 1® Evolution software (for data acquisition and trending)
Confirm rack slot configuration and I/O module compatibility before installation.
Selection Guide
Use the following parameters to confirm the correct part number for your application:
- Probe Active Length: 65 mm (standard for most 3300 XL NSv applications)
- Extension Cable Length: 03 = 3 m — measure the distance from probe tip to driver/oscillator
- Driver Length Code: 05 = 5 m total system — verify total system cable length matches monitor input requirements
- Gap Voltage: Nominal -10 VDC at recommended gap; confirm with your monitor’s input specification
- Target Material: Must be AISI 4140 or equivalent ferromagnetic steel; non-standard targets require recalibration
- Environment: For hazardous area installations, verify ATEX/IECEx certification requirements separately

Replacement & Compatibility FAQ
Q: Can I use a 330930-65-05-05 instead of the 330930-65-03-05?
A: Yes, if the additional cable length (5 m vs 3 m) is acceptable in your installation. The electrical performance is identical.
Q: Is the 330930-65-03-05 compatible with the Bently Nevada 3500 rack?
A: Yes, with the appropriate 3500/42 or 3500/40M monitor module. Verify the I/O module accepts the NSv transducer input.
Q: Can I replace just the probe without replacing the extension cable and driver?
A: Bently Nevada recommends replacing the full matched system (probe + extension + driver) to maintain calibration accuracy. Mixing components from different system sets is not recommended.
Q: Do you supply ATEX-certified versions?
A: Yes. Please specify your hazardous area classification when requesting a quotation and we will confirm the correct certified part number.
Q: What is the lead time for the 330930-65-03-05?
A: Typically 1–5 business days for in-stock units; 2–4 weeks for factory-new orders. Contact us for current availability.
