The Bently Nevada 21000-16-10-15-044-03-02 Proximity Probe Housing Assembly is a critical component used for externally mounting proximity probes. 


  • The 21000 and 24701 Proximity Probe Housing Assemblies are designed for this purpose. They are all-metal and serve as protective enclosures for proximity probes.
  • Two variants are available:
    • 21000 Aluminum Probe Housing Assembly
    • 24701 Stainless Steel Probe Housing Assembly
  • Components include:
    • Dome Cover: Screws into the body of the housing.
    • Threaded Ports: For conduit connections.
    • Probe Sleeve: Optional length.
    • O-rings: Ensure sealing.
    • Reverse Mount Proximity Probe: Installed within.
    • Thread Seal: Prevents leaks.
    • Optional Conduit Fittings.
    • Optional Standoff Adapter (for newer 31000/32000 proximity probe housing assembly with improved features).

Sleeve Length Considerations:

  • Sleeve length depends on the installation location. The probe lead must be longer than the sleeve.
  • Long sleeves (beyond 304 mm or 12 inches) require additional support to reduce vibration. Bently Nevada offers a probe support and oil seal for long sleeves passing through inner bearing housings.

Temperature Ranges:

  • 3300 XL 8 mm Probe: Operating and storage range: -51°C to +177°C (-60°F to +351°F).
  • 3300 XL 11 mm Probe: Operating and storage range: -51°C to +177°C (-60°F to +351°F).
  • 3300 NSV Probe: Operating range: -34°C to +177°C (-30°F to +351°F), storage range: -51°C to +177°C (-60°F to +351°F).
