Rotating Machinery Vibration Monitoring Solution — Bently Nevada 330101-32-70-05-12-05 | 3300 XL Series
Where This Product Is Used
The Bently Nevada 330101-32-70-05-12-05 eddy current proximity sensor is purpose-built for continuous, non-contact vibration and position measurement on rotating machinery in demanding industrial environments. Typical deployment sites include:
- Steam & Gas Turbines — shaft radial vibration and axial position monitoring per API 670
- Centrifugal & Reciprocating Compressors — real-time rotor orbit and eccentricity measurement
- Pumps & Fans — bearing journal displacement monitoring for predictive maintenance
- Gearboxes — gear mesh frequency and shaft runout detection
- Hydro & Wind Turbines — slow-speed shaft monitoring and thrust position
- Marine Propulsion Systems — crankshaft deflection and alignment verification
This sensor is the field-proven standard in petrochemical, power generation, LNG, and offshore platforms where unplanned downtime carries six-figure-per-hour costs.

Why Engineers Specify This Model
- API 670 Compliant — meets the machinery protection standard required by EPC contractors and end-users globally
- Plug-and-Play with 3300 System — direct replacement for existing 3300 XL installations; no recalibration of the driver required when using matched system components
- High-Temperature Probe — rated to 177 °C, suitable for hot-section turbine bearing housings without additional thermal isolation
- Integral Cable Design — eliminates field-splice failure points; 3.2 m integral cable covers most standard bearing-to-junction-box runs
- Broad Frequency Bandwidth — DC to 10 kHz captures both slow-roll runout and high-frequency subsynchronous instabilities
- Proven Field Reliability — millions of operating hours across global fleet; MTBF exceeds 200,000 hours in typical installations

Application-Specific FAQ
Q: Can this sensor monitor non-ferrous targets such as aluminum or titanium impellers?
A: Yes, but the scale factor changes with target material conductivity and permeability. A custom calibration curve must be generated using the actual target material. Contact us for calibration support.
Q: Is this probe compatible with the older 3300/5 and 3300/8 mm systems?
A: The 330101 series is designed for the 3300 XL system. Backward compatibility with legacy 3300/5 drivers requires verification of the driver input impedance — consult Bently Nevada TIL-073 before mixing generations.
Q: What is the maximum gap at installation?
A: The recommended initial gap is 1.0 mm (40 mil), centered in the linear range of 0.25–2.25 mm. This provides equal dynamic range for both inward and outward shaft movement.
Q: Do you offer ATEX-certified versions?
A: Yes. ATEX/IECEx variants of the 3300 XL system are available. Please specify hazardous area classification (Zone 1/2, gas group, temperature class) when inquiring.
Q: Can Konmask provide a Certificate of Conformance (CoC)?
A: Yes. A CoC is provided with every shipment. Third-party inspection (SGS, Bureau Veritas) can be arranged for large orders.
