Bently Nevada 21000-28-10-00-094-04-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-28-10-00-094-04-02 are listed below for quick reference:

Industry Applications for the 21000 Housing Assembly

The CSA Type 4 enclosure and explosion-proof certification (Class I Divisions 1 and 2 Groups C and D; Class II Divisions 1 and 2 Groups E, F, G) make it suitable for direct mounting on compressors, turbines, and pumps. The 9.4-inch probe penetration allows precise positioning within the machine casing, while the 1.0-meter cable provides flexibility for routing to junction boxes.

Installation & Setup Guidance

When installing the 21000-28-10-00-094-04-02, ensure the mounting thread (3/4-14 NPT) is properly sealed with thread sealant to maintain the explosion-proof integrity. The aluminum body with 304 stainless steel sleeve offers corrosion resistance in harsh environments. For non-incendive circuit compliance, connect per drawing 140979. Always verify that the probe tip gap is set according to Bently Nevada specifications before final tightening.

Maintenance & Reliability

Periodic inspection of the housing assembly is recommended to check for physical damage, corrosion, or loosening of fittings. The O-rings and thread seal should be replaced if any degradation is observed. The CSA T5 rating (-50°C to +40°C) and T4 rating (-50°C to +80°C) ensure reliable operation across a wide temperature range. No internal disassembly is required for routine maintenance.

Robust Protection for Critical Vibration Monitoring

Industrial rotating machinery demands reliable vibration monitoring to prevent catastrophic failures. The Bently Nevada 21000-28-10-00-094-04-02 proximity probe housing assembly provides a rugged, explosion-proof enclosure for the 3300 XL 8 mm proximity probe, ensuring accurate shaft vibration and position measurements in hazardous environments.

Compatibility & Integration

The 21000 housing is designed specifically for the 3300 XL 8 mm proximity probe and is fully compliant with API 670 Standard for externally mounted proximity probe housings. It can be ordered with hazardous area approved probes for intrinsically safe applications. The optional standoff adapter (not included in this suffix code) allows additional mounting flexibility.

Selection Guide & Purchasing Advice

When selecting a probe housing assembly, verify that the probe penetration (9.4 in) and cable length (1.0 m) match your machine's dimensions. The 3/4-14 NPT mounting thread is standard for many industrial applications. For North American end users, the CA21000 version is available. Contact AutoDCSTech for lifecycle status and availability before ordering. All units are new, original, and factory-packed with a 12-month warranty.

Troubleshooting & Common Issues

If signal loss or erratic readings occur, first inspect the cable and connector for damage. Verify that the probe tip is not contacting the shaft and that the gap is within specification. Ensure the housing is properly grounded and that all conduit connections are tight. For persistent issues, consult the Bently Nevada manual for the 3300 XL probe.
