Bently Nevada 21000-16-05-00-067-04-02 Proximity Probe Housing Assembly

Description

The 21000-16-05-00-067-04-02 is an aluminum proximity probe housing assembly designed for the external mounting of eddy-current proximity probes. This configuration features a 3300 XL 8mm probe (Option 16), a 0.5 meter probe cable length (Option 05), and is configured with a 6.7 inch probe penetration depth (Option 067). Engineered for reliable mechanical and environmental protection of the transducer system, this assembly ensures the probe is correctly positioned for accurate shaft vibration and axial position measurement.

This 21000 series housing is compliant with API 670 standards for externally mounted proximity probes. It is constructed from a robust aluminum body, providing durability in demanding industrial environments. This specific unit utilizes a 3/4-14 NPT mounting thread (Option 02) and includes a single 3/4-14 NPT plug (Option 04) for the conduit interface, with no standoff adapter (Option 00) included in this assembly.

Installation Guidelines

Ensure the mounting threads are properly sealed if required by the application environment. For installations involving probe penetration lengths exceeding 300 mm (12 in), additional sleeve support must be added near the probe to prevent resonance. Verify that the probe penetration depth (Option 067) matches the machine case requirements during installation. Do not expose 3300 XL probes to temperatures below -34 degC (-30 degF) to avoid pressure seal damage.

Compliance and Certifications

This housing assembly is designed for use in environments requiring compliance with API 670 standards. When combined with appropriate components, it supports intrinsically safe and explosion-proof applications as defined by CSA ratings. Users should consult the specific Approvals Quick Reference Guide (108M1756) for detailed regional and hazardous area certification status.
