Turbomachinery Vibration Monitoring Solution – Bently Nevada 330103-03-07-05-02-00 | 3300 XL Series
Where This Product Is Used
The Bently Nevada 330103-03-07-05-02-00 Proximity Transducer System is engineered for continuous, non-contact measurement of shaft radial vibration, axial position, and differential expansion in rotating machinery. It is routinely specified in the following industrial environments:
- Steam & Gas Turbines – Real-time shaft orbit and eccentricity monitoring to prevent catastrophic bearing failure.
- Centrifugal Compressors – Radial vibration surveillance on high-speed impeller shafts in petrochemical and LNG plants.
- Pumps & Fans – Continuous position feedback for critical process pumps in power generation and water treatment.
- Gearboxes – Gear mesh frequency analysis and shaft runout detection in heavy industrial drives.
- Marine Propulsion Systems – Shaft monitoring on diesel-electric vessels and offshore platform drives.

Why Engineers Specify This Model
- Drop-in 3300 XL Compatibility – Fully interchangeable with existing 3300 XL Proximitor® monitors; no recalibration of the monitoring system required.
- Extended Cable Configuration – The 3 m + 7 m probe-plus-extension combination covers the majority of turbomachinery bearing-to-rack distances without field splicing.
- High-Temperature Probe – Rated to 121 °C continuous, suitable for hot-section bearing housings on steam turbines.
- Proven EMI Immunity – Coaxial cable construction and Proximitor® driver design reject electrical noise in VFD-dense environments.
- API 670 Alignment – Designed to meet the measurement performance requirements of API Standard 670 (Machinery Protection Systems).

Application-Specific FAQ
Q: Is the 330103-03-07-05-02-00 compatible with the older 3300 (non-XL) Proximitor® monitors?
A: No. The 3300 XL series uses a revised scale factor and connector standard. Use 330103-XX-XX-05-02-00 probes only with 3300 XL Proximitor® drivers.
Q: What target material correction is needed for stainless steel shafts?
A: Stainless steel (e.g., 316L) requires a target material correction factor. Bently Nevada provides correction curves; typical scale factor deviation is −15% to −25% vs. AISI 4140. Recalibration at the Proximitor® is required.
Q: Can this probe be used for axial position (thrust) measurement?
A: Yes. With appropriate mounting hardware and a thrust collar target, the 330103 probe is suitable for axial position measurement within its linear range (0.25–2.25 mm).
Q: What is the maximum shaft speed this system can monitor?
A: The 3300 XL system is rated for shaft speeds up to 600,000 RPM (10,000 Hz frequency response), making it suitable for high-speed compressors and expanders.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes. A CoC is available upon request at no additional charge. CMTC (Calibration and Material Test Certificate) can be arranged for critical applications.
