Bently Nevada 21000-16-10-00-144-03-02 Proximity Probe Housing Assembly

Bently Nevada 21000-16-10-00-144-03-02 Proximity Probe Housing Assembly The Bently Nevada 21000-16-10-00-144-03-02, also cataloged as the 21000 proximity probe housing assembly, serves as a dedicated enclosure for 3300 XL 8 mm probes, enabling secure mechanical penetration and electrical routing in API 670 compliant monitoring systems. Part Number Breakdown Probe Option (-16): Accommodates 3300 XL 8 mm proximity probe with connector Cable Length (-10): 1.0 m (39 in) probe cable length Standoff Adapter (-00): No standoff adapter included Penetration Depth (-144): 14.4 in (366 mm) probe penetration length Fittings Option (-03): One 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer, cable seal grip with multiple grommet sizes Mounting Thread (-02): 3/4-14 NPT mounting thread Hardware Specifications Parameter Specification Model 21000-16-10-00-144-03-02 Brand Bently Nevada (Baker Hughes) Origin USA Weight Not specified Dimensions Penetration depth 14.4 in; cable length 1.0 m Operating Temp Not specified Power Consumption Passive housing assembly Core Performance Explosion-proof aluminum body with 304 stainless steel sleeve; API 670 compliant; CSA Type 4 enclosure rating Eddy-Current Probe Scaling and Gap Voltage Validation The housing assembly is engineered to maintain calibrated eddy-current probe scaling by ensuring precise mechanical alignment of the probe tip. Gap voltage validation at -10 VDC reference points is supported through stable penetration depth, enabling accurate shaft displacement monitoring. Coaxial shielding and reducer fittings suppress cross-talk and maintain electrical integrity in multi-channel installations. Frequently Asked Questions Q: Can the housing assembly be installed in hazardous zones without additional certification? A: Yes. The assembly is explosion-proof and meets CSA Type 4 and API 670 standards, suitable for hazardous industrial areas. Q: Does the 14.4 in penetration depth require special calibration? A: No. The penetration depth is mechanically defined; calibration is performed at the proximitor level. Q: Are reducer fittings interchangeable? A: Reducer fittings are supplied with multiple grommet sizes to accommodate cable variations but must remain within specified NPT thread standards. Field Installation Guidelines Engage 3/4-14 NPT threads with a minimum of 5 turns to ensure mechanical stability. Ground shielding at the proximitor end only to prevent ground-loop interference. Verify sealing integrity of the cable grip and grommet to maintain explosion-proof rating. Route cables away from high-voltage conductors to minimize induced noise. Confirm compliance with API 670 and CSA Type 4 requirements before energizing the system.
