Rotating Machinery Vibration Monitoring Solution – Bently Nevada 330101-00-18-05-02-05 | 3300 XL Series
Where This Product Is Used
The Bently Nevada 330101-00-18-05-02-05 is a high-precision eddy-current proximity transducer system engineered for continuous, non-contact vibration and position measurement on rotating machinery. Typical deployment environments include:
- Steam & Gas Turbines – shaft radial vibration, differential expansion, and eccentricity measurement on power-generation units up to 1,500 MW.
- Centrifugal Compressors – real-time rotor orbit monitoring in petrochemical, LNG, and refinery trains to detect instability before catastrophic failure.
- Pumps & Fans – bearing journal displacement tracking in critical BFW pumps, cooling-water pumps, and induced-draft fans.
- Gearboxes – axial thrust position monitoring to protect thrust bearings in high-speed gear trains.
- Marine Propulsion Systems – shaft-line vibration surveillance on diesel-electric and LNG-fuelled vessels.
Industries served: Oil & Gas, Power Generation, Petrochemical, Pulp & Paper, Marine, and Water Treatment.

Application-Specific FAQ
Q: Is the 330101-00-18-05-02-05 compatible with the Bently Nevada 3500 rack?
A: Yes. The 3300 XL probe is fully compatible with the 3500/40M Proximitor® Monitor when paired with the correct 3300 XL extension cable and driver. No re-calibration is required.
Q: What is the difference between the 330101 and 330103 probe series?
A: The 330101 is the standard 3300 XL probe (5 mm tip, M8 thread). The 330103 is the 3300 XL 8 mm probe with a larger tip diameter for longer linear range. Selection depends on bearing clearance and required measurement gap.
Q: Can this probe be used in a hydrogen-cooled generator?
A: Yes, provided the installation complies with the applicable hazardous-area classification. The ATEX/IECEx certification covers hydrogen (Group IIC) atmospheres.
Q: What is the maximum cable run from probe to monitor?
A: The 3300 XL system supports a total cable length (integral + extension) of up to 9 m (30 ft) while maintaining calibrated scale factor. Longer runs require system re-calibration.
Q: Do you provide a warranty?
A: All items are sold with a 90-day functional warranty unless otherwise stated. Extended warranty and exchange programs are available — contact us for details.
