Turbine & Rotating Machinery Vibration Monitoring Solution – Bently Nevada 330171-00-20-90-02-00 | 3300 XL Series
Where This Product Is Used
The Bently Nevada 330171-00-20-90-02-00 is a high-precision eddy-current proximity transducer engineered for continuous vibration and position monitoring of rotating machinery in mission-critical industrial environments. Typical deployment sites include:
- Steam & Gas Turbines – shaft radial vibration and axial position measurement in power generation plants
- Centrifugal Compressors – real-time rotor orbit monitoring in petrochemical and LNG facilities
- Pumps & Blowers – bearing journal displacement tracking in water treatment and HVAC systems
- Gearboxes & Expanders – differential expansion and eccentricity monitoring in refinery trains
- Marine Propulsion Systems – shaft vibration surveillance on vessel drive trains

Application-Specific FAQ
Q: Is the 330171-00-20-90-02-00 compatible with the Bently Nevada 3500 system?
A: Yes, when paired with the appropriate 3500-series Proximitor and monitor card. Verify the driver input impedance matches your 3500/40M channel configuration.
Q: What is the maximum shaft speed this transducer can monitor?
A: The eddy-current technology is frequency-independent up to the bandwidth of the paired Proximitor driver (typically DC to 10 kHz), making it suitable for machinery operating from 0 to 60,000 RPM.
Q: Can this probe be used on non-ferrous shafts?
A: Performance is optimized for AISI 4140 steel targets. For non-ferrous or exotic alloy shafts, a calibration correction factor must be applied. Contact our engineering team for target material assessment.
Q: What is the difference between the -90-02-00 and -90-00-00 suffix?
A: The suffix encodes connector type and cable jacket material. The -02-00 variant features a stainless-steel armored jacket suitable for harsh environments. Confirm your installation requirements before substituting suffixes.
Q: Do you provide calibration certificates?
A: Factory calibration data is available. Third-party NIST-traceable calibration certificates can be arranged upon request at additional cost.
