Configured for secure transducer integration in 3300 Proximity Transducer System platforms, the Bently Nevada 21000-16-10-35-098-03-02 (21000-16-10-35-098-03-02 Proximity Probe Housing Assemblies) provides direct physical/electrical execution for mounting probes in rotating machinery applications.

Suffix Configuration Matrix

The 21000 series utilizes a defined ordering syntax to specify mechanical interface requirements. The suffix -16-10-35-098-03-02 designates the specific thread dimensions, sleeve length, standoff adapter configuration, and conduit seal type required to maintain measurement stability within the host machine casing.

Hardware Specifications

Transducer System Rotor Dynamics

The housing assembly is instrumental in maintaining the probe-to-target gap required for precise rotor dynamics monitoring. Proper installation is required to facilitate gap voltage validation (-10 VDC targets), ensuring the transducer operates within the calibrated linear displacement range. The mechanical rigidity of the assembly provides cross-talk suppression by isolating the probe from extraneous machine casing vibrations that could otherwise couple into the velocity or displacement signal paths, thereby maintaining the fidelity of phase reference and vibration amplitude data.

Ordering Inclusions

Field Installation Guidelines

• Mechanical Alignment: Ensure the probe bore is accurately centered relative to the shaft target area during housing installation.

• Torque Application: Tighten assembly components to specified limits to ensure a pressure-tight seal against oil and environmental contaminants.

• Grounding: Verify that the stainless steel sleeve maintains electrical continuity with the machine frame for effective electromagnetic shielding.

• Probe Depth: Adjust the probe insertion depth to achieve the nominal gap as dictated by the 3300 XL system calibration curve.

• Conduit Management: Secure conduit connections to the housing ports to prevent mechanical stress on the coaxial cable and connector interface.

Frequently Asked Questions

• Can the housing be used in high-pressure environments? The housing assembly is pressure-rated; confirm the specific maximum pressure rating in the manual for the target application.

• Is the housing material compatible with corrosive lubricants? The use of 304 stainless steel in the sleeve provides resistance to many common industrial lubricants and chemicals.

• How is electrical ground maintained? The assembly is designed to provide a continuous ground path from the probe housing to the machine frame through the threaded interface.

• Can I reuse the O-rings during probe replacement? It is standard technical practice to replace sealing O-rings during maintenance to guarantee environmental integrity.

• Does the housing assembly introduce measurement noise? No, when correctly installed and tightened, the assembly is a passive mechanical component that does not add noise.

• Is the probe sleeve replaceable? The internal sleeve is a specified component; structural damage typically requires replacing the entire assembly.

• How do I confirm the gap distance? Gap distance must be verified using the Proximitor output voltage; confirm the reading is at the -10 VDC target at the nominal gap.

• What happens if the conduit is not properly sealed? Improper conduit sealing allows for moisture and debris ingress, which can lead to connector corrosion and signal degradation.
