Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or equivalents for the 330903-00-09-05-02-05. Always verify system compatibility before substitution:
- Bently Nevada 330903-00-09-05-02-00 — Same transducer, 0 m extension (direct mount)
- Bently Nevada 330903-00-09-05-02-10 — 10 m extension cable variant
- Bently Nevada 330905-00-09-05-02-05 — 3300 XL 8 mm standard series equivalent
- Bently Nevada 330780-50-00 — 3300 XL 8 mm proximity transducer (alternative series)
- Epro PR6423/010-030 — Third-party equivalent, eddy-current proximity sensor, compatible with 3300 series drivers
- Metrix ST5484E — Functional equivalent for vibration monitoring applications
Note: Replacement models must be matched with the correct driver (e.g., 3300 XL driver) and extension cable to maintain system calibration.
Why Choose the Original Model

- OEM Compliance: Required for API 670 compliance in turbomachinery protection systems.
- Long-Term Support: Bently Nevada provides full documentation, calibration certificates, and traceability.
- Proven Reliability: Deployed globally in power generation, oil & gas, and petrochemical plants.
Typical Applications
- Steam and gas turbine shaft vibration monitoring
- Compressor radial and axial position measurement
- Pump and motor bearing displacement sensing
- Gearbox and expander rotor dynamics analysis
- API 670-compliant machinery protection systems
System Compatibility
The 330903-00-09-05-02-05 is designed to operate as part of the Bently Nevada 3300 XL NSv System, which includes:
- Driver: 3300 XL NSv Driver (e.g., 330180-X1-05)
- Extension Cable: 330130-045-00-00 (matched 5 m cable)
- Monitor: Compatible with 3500/40M, 3500/42M, and 3500/45 monitor modules
- System Scale Factor: 200 mV/mil (7.87 V/mm)
Do not mix components from different series (e.g., 3300 5 mm vs. 3300 XL 8 mm) without recalibration.

Replacement & Compatibility FAQ
Q: Can I use a 330903-00-09-05-02-00 instead of the -02-05?
A: Yes, if you are providing your own 5 m extension cable. The transducer body is identical; only the included extension cable length differs.
Q: Is the 330903-00-09-05-02-05 compatible with the 3500 series monitors?
A: Yes, when used with the correct 3300 XL NSv driver module. The 3500/40M and 3500/42M are fully compatible.
Q: Can an Epro PR6423 replace this unit?
A: Functionally similar, but the Epro unit requires driver reconfiguration and scale factor verification. Not a drop-in replacement for API 670 systems without re-engineering.
Q: Do you provide calibration certificates?
A: Yes. Calibration documentation is available for all units upon request.
