Technical Specifications Breakdown

Key parameters for the 21000-34-10-00-030-04-02 are listed below for quick reference:

Industry Applications: Protecting Critical Assets

This housing assembly is purpose-built for externally mounted proximity probes on turbomachinery, compressors, and pumps. The aluminum body with 304 stainless steel sleeve resists corrosion in refinery and chemical plant environments. The selectable hazardous area approvals (via probe option 34) make it suitable for use in explosive atmospheres when paired with appropriate conduit fittings. The 3/4-14 NPT mounting thread and single plug fitting simplify installation into standard process connections.

Installation & Setup Guidance

When installing the 21000-34-10-00-030-04-02, ensure the probe cable length of 1.0 m is sufficient for the routing path. The assembly includes a dome cover, threaded ports, probe sleeve, O-rings, reverse mount proximity probe, and thread seal. Use the provided 3/4-14 NPT plug to seal unused conduit ports. For explosion-proof installations, verify that the housing is the CA version and that the fitting options E:00, E:01, E:02, or E:04 are ordered. Always follow API 670 guidelines for externally mounted housings.

Maintenance & Reliability

Periodically inspect the O-rings and thread seal for degradation. Verify that the dome cover is fully tightened and that conduit connections remain secure. The assembly is certified as CSA Type 4 enclosure, providing protection against water ingress and dust. No disassembly of the probe is required for routine inspection.

Robust Protection for Critical Vibration Monitoring

Industrial rotating machinery demands precise, reliable vibration measurement to prevent catastrophic failures. The Bently Nevada 21000-34-10-00-030-04-02 proximity probe housing assembly provides a rugged, certified enclosure for the 3300 XL 8 mm probe, ensuring accurate data in harsh environments. This assembly simplifies installation and enhances probe longevity, reducing unplanned downtime.

Selection Guide & Purchasing Advice

When ordering a replacement or new installation, confirm that the probe penetration (3.0 in) matches your measurement gap requirements.
