Why Choose the Original Model
- Factory-calibrated: Each probe is calibrated against a certified target to ensure ±1% sensitivity accuracy.
- System-matched: Designed specifically for the 3300 NSv monitor/driver pair — no re-scaling required.
- Proven reliability: Widely deployed in turbines, compressors, and pumps across power generation and petrochemical industries.
- Warranty & traceability: Supplied with full documentation and traceable calibration certificate.
Typical Applications
- Steam and gas turbine shaft vibration monitoring
- Centrifugal compressor radial and axial position measurement
- Pump and motor eccentricity and runout detection
- Gearbox and expander condition monitoring
- API 670 machinery protection systems
System Compatibility
The 330904-00-25-10-02-00 probe is designed to operate within the following Bently Nevada system configurations:
- Monitor: 3300 NSv Monitoring System
- Driver/Proximitor: 330180 NSv Proximitor Sensor
- Cable Extension: 330130 / 330140 series extension cables
- System Standard: API 670 4th Edition compliant
Not compatible with 3300 XL 5mm or 8mm probe drivers without recalibration. Consult your system engineer before substitution.
Selection Guide
Use the following decision criteria to select the correct 330904 variant for your application:
- Tip diameter: 25 mm is standard for most 3300 NSv installations. Use 8 mm probes (330903 series) for tight-clearance applications.
- Cable length: The -10- segment encodes 1.0 m integral cable. Match to your proximitor mounting distance.
- Connector type: -02- is the standard connector. Confirm your junction box or proximitor input type.
- Temperature rating: Standard model rated to 177 °C. For higher ambient temperatures, specify the 330905 high-temp variant.
- Target material: Optimized for AISI 4140 steel. Non-standard target materials require sensitivity correction factors.

Replacement & Compatibility FAQ
Q: Can I use a 330903 probe as a direct replacement for the 330904?
A: The 330903 (8 mm tip) and 330904 (25 mm tip) have different linear ranges and sensitivities. They are not interchangeable without driver recalibration.
Q: Is the 330904-00-25-10-02-00 compatible with the 3500 series monitors?
A: No. The 3500 series uses different Proximitor sensors. Use 330730 or 330900 series probes for 3500 system compatibility.
Q: What is the lead time for this part?
A: In-stock units ship within 3–5 business days. Contact us for current availability and expedited options.
