The Bently Nevada 21000-16-05-00-043-03-02, also cataloged as the 21000 Proximity Probe Housing Assemblies, operates as a dedicated hardware component for physical positioning and environmental isolation of proximity sensors within Proximity Probe Housing Assemblies. The unit provides an externally adjustable mounting platform, allowing insertion, depth adjustment, and extraction of proximity probes directly through the machinery casing boundary while maintaining process pressure and fluid containment.

Hardware Parameter Specifications

Transducer Calibration and Cross-Talk Suppression

The architectural design of the Bently Nevada 21000-16-05-00-043-03-02 housing directly isolates the proximity probe from external structural stresses that can degrade eddy-current probe scaling. By providing a rigid mechanical coaxial alignment relative to the observed target shaft, it prevents structural resonance from introducing errors into high-velocity rotor dynamics profiles. This mechanical stability ensures repeatable gap voltage validation (-10 VDC targets) during baseline calibration routines. Additionally, the continuous metallic construction of the housing creates an effective electrostatic barrier, providing cross-talk suppression between parallel proximity sensor loops running inside shared structural instrumentation conduits.

Package Shipping Contents

• 1 x Internal sealing packing gland module

• 1 x Compression washer set

• 2 x Heavy industrial hex locknuts

Field Installation Protocols

1. Verify that the machine casing port mating threads precisely correspond with the housing suffix variant (-02 code) prior to installation.

2. Ensure a minimum thread engagement of 5 full threads into the machine casing wall to guarantee appropriate mechanical pressure boundary containment.

3. Insert the proximity probe into the internal sleeve assembly, taking care not to scrape or impact the sensitive probe tip against the housing bore.

4. Execute real-time gap voltage validation (-10 VDC targets) using a calibrated digital voltmeter linked to the proximity transducer system monitor while adjusting the external sleeve depth.

5. Tighten the primary external hex locknuts to the specified industrial torque limit to secure the probe depth configuration against continuous machinery vibration.

Dispatch and Packaging Protocol

Delivery time: 2-7 days when payment finish, routed via global express carriers such as DHL, FEDEX, or UPS. The component is shipped exclusively in anti-static industrial packaging featuring molded high-density foam isolation to protect the precision machined threads and internal sealing surfaces from transit shock and atmospheric oxidation.

Technical Performance FAQ

Q: How does this housing preserve eddy-current probe scaling accuracy across variable operating temperatures?

A: The housing materials are selected for thermal stability, limiting mechanical expansion variations along the insertion axis to ensure the probe distance to the target shaft remains unaltered by ambient temperature changes.

Q: What actions prevent process oil bypass during mechanical adjustment under dynamic machine operating cycles?

A: The internal compression packing gland isolates the internal machine pressure, providing an airtight boundary during linear adjustment of the probe sleeve.

Q: Is a separate electrical isolation kit required to prevent ground loops from degrading cross-talk suppression?

A: No. The structural grounding path is completed natively through the casing thread engagement, establishing a uniform reference potential that maximizes cross-talk suppression without external wiring modifications.
