Bently Nevada 21000-00-00-00-110-04-02 Proximity Probe Housing Assemblies

Description

The 21000-00-00-00-110-04-02 is an aluminum proximity probe housing assembly designed for the external mounting of eddy-current proximity probes. This specific configuration features no included probe (Option 00), no probe cable (Option 00), and no standoff adapter (Option 00), with a probe penetration depth of 11.0 inches (Option 110). It is equipped with one 3/4-14 NPT plug (Option 04) and a 3/4-14 NPT mounting thread (Option 02).

This assembly provides a protective environment for probes, ensuring they are shielded from industrial hazards while maintaining accurate proximity measurement alignment. It adheres to the American Petroleum Institute (API) 670 standard for externally mounted proximity probe housings, making it a reliable choice for monitoring axial position and shaft vibration in rotating machinery such as turbines, compressors, and pumps.

Installation Guidelines

• Ensure the housing is mounted securely to the machine case to minimize vibration effects on the probe.
• Use appropriate thread sealant on NPT connections to maintain pressure integrity.
• Verify the probe gap and penetration depth during installation to ensure the probe tip is positioned correctly relative to the target surface.
• For installations involving conduit, ensure fittings are tightened to manufacturer specifications to prevent moisture ingress.
