Compatible Replacement & Equivalent Models
When the OEM part is unavailable or lead times are extended, the following models are functionally equivalent or drop-in replacements:
- 330903-00-10-05-02-05 – Standard 3300 NSv probe, same geometry, slightly different cable routing
- 330905-00-10-05-02-05 – Extended-temperature variant for high-heat environments
- 330780-50-00 – 3300 XL 8 mm probe (requires extension cable adapter)
- Emerson 330104-00-10-05-02-05 – Post-acquisition equivalent under Emerson branding
- Third-party NSv-compatible probes – Must match M10 thread, 200 mV/mil scale factor, and coaxial connector spec; verify with system integrator before installation
Note: Always verify gap range, scale factor, and connector compatibility before substituting. Konmask.com supplies genuine Bently Nevada parts with full traceability.
Why Choose the Original Model
- Factory-calibrated scale factor ensures direct compatibility with 3300 NSv monitors without recalibration
- Integral cable design eliminates connector joints that can introduce signal noise in high-vibration environments
- Proven MTBF exceeding 100,000 hours in continuous industrial service
- OEM traceability – each unit ships with Bently Nevada certificate of conformance
- Regulatory compliance – CE and ATEX markings accepted by most plant safety authorities globally
Typical Applications
- Steam and gas turbine shaft radial vibration monitoring
- Centrifugal compressor rotor position measurement
- Pump and motor bearing proximity sensing
- Gearbox shaft eccentricity detection
- Axial thrust position monitoring on rotating shafts
System Compatibility
The 330904-00-10-05-02-05 is designed to operate within the Bently Nevada 3300 NSv monitoring system and is compatible with:
- 3300/16 and 3300/20 monitor cards
- 3500 Series rack-based monitoring systems (with appropriate I/O module)
- System 1 Condition Monitoring Software (Emerson)
- 3300 XL extension cables (330130 series)
- Proximitor sensors (330180 series)
Selection Guide
Use the table below to identify the correct 330904 variant for your application:
- Probe tip length: 10 mm standard | 25 mm for deep-bore installations
- Cable length: 05 = 5 m | 10 = 10 m | 15 = 15 m (specify at order)
- Thread: 02 = M10 x 1.0 | 03 = 3/8-24 UNF (imperial installations)
- Connector style: 05 = standard coaxial | 06 = armored cable variant
- Temperature rating: Standard (-35 to +177 C) or HT variant for above 177 C
If your application requires a non-standard configuration, contact support@konmask.com with your shaft diameter, gap target, and monitor card model for a tailored recommendation.

Replacement & Compatibility FAQ
Q: Can I use a 330903 probe in place of the 330904?
A: In most cases yes – both share the same scale factor and connector. Verify thread size and cable length match your installation before swapping.
Q: Is this probe compatible with the Bently Nevada 3500 system?
A: Yes, with the appropriate 3500 I/O module. Confirm the monitor card accepts 200 mV/mil input.
Q: Do you supply ATEX-certified units?
A: Yes. Specify ATEX requirement at time of order and we will provide the relevant zone-classified variant with documentation.
Q: What is the lead time for genuine stock?
A: In-stock units ship within 3-5 business days. For out-of-stock items, typical lead time is 4-8 weeks from factory.
Q: Can Konmask.com provide a calibration certificate?
A: Yes. Factory calibration certificates are available; third-party NIST-traceable calibration can be arranged on request.
