Turbine & Compressor Vibration Monitoring Solution – Bently Nevada 330906-02-12-70-02-05 | 3300 XL Series
Where This Product Is Used
The Bently Nevada 330906-02-12-70-02-05 is a precision 8 mm eddy-current proximity probe engineered for continuous, non-contact shaft vibration and axial position measurement in rotating machinery. Typical deployment environments include:
- Steam & Gas Turbines – radial shaft vibration monitoring per API 670
- Centrifugal & Axial Compressors – rotor dynamic analysis and surge detection
- Pumps & Fans – bearing journal orbit measurement
- Gearboxes – gear mesh frequency and eccentricity tracking
- Hydro Turbines & Motors – thrust position and differential expansion
- Petrochemical & Refinery Plants – continuous online machinery protection systems
- Power Generation Facilities – integrated with DCS/SCADA for predictive maintenance

Application-Specific FAQ
Q: Is the 330906-02-12-70-02-05 compatible with older Bently Nevada 3300 (non-XL) systems?
A: No. The 3300 XL series uses a different driver impedance. Use 330905-XX series probes for legacy 3300 systems.
Q: Can this probe be used on non-ferrous targets (e.g., titanium or aluminum rotors)?
A: Yes, but sensitivity and linearity will differ. A target-specific calibration is required. Contact us for application support.
Q: What is the maximum shaft speed this probe can monitor?
A: The 10 kHz bandwidth supports shaft speeds up to approximately 600,000 RPM, well beyond typical turbomachinery operating ranges.
Q: Do you supply the full matched set (probe + cable + driver)?
A: Yes. We can supply individual components or complete matched sets. Specify your cable length and driver model when enquiring.
Q: Is an ATEX-rated version available?
A: Yes. Please specify your hazardous area classification (Zone 1/2, Gas Group, Temperature Class) when requesting a quote.
