Turbine & Rotating Machinery Vibration Monitoring Solution — Bently Nevada 21000-27-10-15-047-03-02 | 3300 XL Series
Where This Product Is Used
The Bently Nevada 21000-27-10-15-047-03-02 Proximity Probe Housing Assembly is purpose-built for continuous, non-contact vibration and position measurement in high-speed rotating machinery environments. Typical deployment sites include:
- Steam and gas turbine bearing housings in power generation plants
- Centrifugal and axial compressors in oil & gas upstream/downstream facilities
- Turbopumps and boiler feed pumps in petrochemical complexes
- Gearboxes and expanders in LNG liquefaction trains
- Marine propulsion shafting systems requiring continuous shaft orbit monitoring
- Pulp & paper mill refiners and agitators with critical uptime requirements
Engineers specify this housing assembly wherever a rugged, field-replaceable probe mount is required to maintain precise radial gap and alignment under thermal cycling, vibration, and process fluid exposure.

Why Engineers Specify This Model
- Drop-in replacement compatibility — direct fit for existing 3300 XL probe ports without machining modifications
- 316 SS construction — resists H₂S, chloride-laden process gases, and high-pressure steam condensate
- Precision-machined tip recess — maintains ±0.025 mm gap repeatability after reinstallation
- Integrated locknut design — prevents probe migration under sustained vibration loads up to 50 g
- OEM-equivalent performance — validated against Bently Nevada factory calibration curves for 3300 XL transducer systems
- Field-serviceable — housing can be replaced without removing the probe cable conduit, minimising plant downtime

Application-Specific FAQ
Q: Is this housing compatible with the older 3300 (non-XL) probe series?
A: The 3300 XL housing uses the same thread form as the legacy 3300 series in most configurations, but always verify the probe tip diameter and thread suffix against your existing installation drawings before ordering.
Q: Can this housing be used in a hydrogen-cooled generator environment?
A: Yes. The 316 SS body and sealed IP67 rating make it suitable for hydrogen-cooled stator environments, provided the probe cable is rated for H₂ service. Consult Bently Nevada application note AN-028 for full guidance.
Q: What is the recommended installation torque for the locknut?
A: Bently Nevada specifies 20–25 N·m for the 3/8–24 UNF locknut. Always use a calibrated torque wrench and re-check gap after final torque.
Q: Do you provide calibration certificates?
A: Factory calibration certificates are available for new OEM units. For surplus stock, we provide dimensional inspection reports. Contact us to discuss your site’s documentation requirements.
Q: What is the lead time for quantities above 10 units?
A: Typically 5–10 business days depending on warehouse stock. For project quantities (20+), contact us early to reserve allocation.
