Description
21000-16-05-00-103-03-02: 3300 XL 8 mm proximity probe housing assembly, featuring Option 16 (3300 XL 8 mm probe), Option 05 (0.5 m probe cable), Option 00 (no standoff adapter), Option 103 (10.3 in probe penetration), Option 03 (cable seal grip), and Option 02 (3/4-14 NPT mounting thread).
This Bently Nevada 21000 series housing assembly is a standardized, externally mounted solution used for securing proximity probes in industrial rotating machinery applications. It provides a robust, environmentally sealed environment for the transducer system, protecting the probe and cable connection while facilitating precise axial position and vibration monitoring. This configuration is engineered for standard industrial environments, utilizing an aluminum body with a 304 stainless steel sleeve to ensure structural integrity and effective thermal management for the installed 3300 XL 8 mm probe.
Features
- Option 16: Includes a factory-integrated 3300 XL 8 mm proximity probe
- Option 05: Equipped with a 0.5 m (20 in) probe cable for compact connection requirements
- Option 103: Precise 10.3 inch (261.6 mm) probe penetration depth
- Option 03: Cable seal grip fitting provides secure, weather-resistant ingress protection
- Option 02: Standard 3/4-14 NPT mounting thread for straightforward installation into machine casings
- Option 00: Direct mount configuration without standoff adapter for space-constrained installations
- Construction: Aluminum body with 304 stainless steel sleeve for resistance to vibration and environmental factors
Applications
This proximity probe housing assembly is used in heavy industrial sectors for monitoring critical rotating machinery, including:
- Steam and gas turbines
- Centrifugal compressors and blowers
- Large electric motors and generators
- Reciprocating compressors (where non-contact monitoring is required)
- Pumps and gearboxes in petrochemical and refining facilities

Installation Guidelines
Ensure the probe cable is longer than the internal sleeve length. For probe penetration depths exceeding 300 mm (12 in), additional sleeve support is required to prevent resonance. When installing, verify the probe gap settings as specified in the transducer system documentation. Ensure all thread engagements are properly sealed if required by the specific hazardous area classification of the installation site.
