Bently Nevada CA21000-00-00-00-015-02-02 Explosion-Proof Housing Assemblies

Functional Description

The Bently Nevada CA21000-00-00-00-015-02-02, also identified as the Bently Nevada CA21000 Explosion-Proof Housing Assembly, is engineered for mechanical containment and environmental isolation of proximity probe connections within the 3300 or 3300 XL Proximity Transducer System. The physical enclosure provides a flameproof seal around the internal electrical connections, isolating potential ignition sources from hazardous atmospheric gases. Mechanical conduit interfaces allow routing of field wiring while maintaining explosion-proof system integrity up to the sensor junction point.

Performance & Physical Data

System Compatibility Notes

Q: How does the internal probe clearance affect structural safety and signal path alignment?

A: The 1.5 in probe penetration option determines the specific length available for the internal probe body inside the housing adapter. Ensure that the total stack-up height of the proximity probe body matches this depth to avoid mechanical loading on the cable connection or terminal face when the enclosure cap is fully torqued.

Q: Can this housing be integrated into non-NPT conduit networks?

A: The mechanical mounting thread is specified exclusively as 3/4-14 NPT. Integration into metric or alternative conduit infrastructures requires the installation of certified flameproof or explosion-proof thread adapters matching local explosion protection regulatory standards.

Installation & Safety Protocols

• Mechanical torque application on the main 3/4-14 NPT mounting thread must follow standard engineering specifications for explosion-proof fittings to achieve proper thread engagement and maintain environmental sealing.
• Inspect the critical flame-path threads on the enclosure housing cap prior to final assembly; ensure no debris, damage, or non-approved thread compounds compromise the machined tolerances.
• Implement appropriate thread lubrication using only manufacturer-approved non-hardening anti-seize compound to avoid thread galling during removal or field maintenance.
• Verify that the dual explosion-proof fittings are securely locked into the housing entry ports and that the field wiring conduit seals are poured with compound in compliance with hazardous area regulations.
