Turbomachinery Vibration Monitoring Solution – Bently Nevada 21000-16-10-00-217-04-02 | 3300 XL Series
Where This Product Is Used
The Bently Nevada 21000-16-10-00-217-04-02 Proximity Probe Housing Assembly delivers precision non-contact shaft vibration and position measurement in critical rotating machinery. Typical deployment environments include:
- Steam & Gas Turbines – Radial vibration and axial position monitoring on high-speed shafts in power generation plants
- Centrifugal Compressors – Bearing journal orbit analysis in petrochemical and LNG compression trains
- Pumps & Fans – Continuous shaft displacement monitoring in critical process loops
- Gearboxes – Gear mesh frequency and shaft runout detection in heavy industrial drives
- Marine Propulsion Systems – Shaft alignment and vibration surveillance on vessel drive trains
This housing assembly provides the mechanical interface that precisely positions the eddy-current probe tip at the correct gap distance from the target shaft, ensuring measurement accuracy and long-term signal stability in harsh plant environments.

Application-Specific FAQ
Q: Is the 21000-16-10-00-217-04-02 compatible with the Bently Nevada 3500/42 vibration monitor?
A: Yes. This housing assembly is part of the 3300 XL transducer system, fully compatible with the 3500/42 and 3500/46 monitor modules when used with the correct Proximitor driver.
Q: What is the standard probe gap for this assembly?
A: The recommended initial gap is 1.0 mm (40 mil) for 8mm probes, yielding a –10 VDC output at mid-range. Refer to the Bently Nevada calibration curve for your specific driver.
Q: Can this housing be used in a hazardous (classified) area?
A: Certain configurations carry ATEX/IECEx certification. Please confirm the area classification with our technical team before ordering.
Q: Do you offer calibration certificates?
A: Yes. Factory calibration documentation is available upon request. Third-party NIST-traceable calibration can be arranged for an additional fee.
Q: What is the difference between the 21000 and 330100 series probe assemblies?
A: The 21000 series uses a 5/16-28 UNF thread and is designed for the 3300 XL 8mm transducer system. The 330100 series targets the standard 3300 8mm system. Both are compatible with the 3500 monitor rack but use different Proximitor drivers.
