Bently Nevada 21000-28-05-20-095-04-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-28-05-20-095-04-02 are listed below for quick reference:

Industry Applications for the 21000 Housing Assembly

This housing assembly is engineered for continuous vibration monitoring on critical rotating machinery such as compressors, turbines, pumps, and electric motors in refineries, chemical plants, and power generation facilities. Its CSA Type 4 enclosure and explosion-proof rating make it suitable for Class I Divisions 1 and 2 Groups C and D, as well as Class II Divisions 1 and 2 Groups E, F, and G. The 3300 XL 8 mm probe provides reliable shaft displacement and eccentricity measurements, supporting API 670 compliance.

Installation & Setup Guidance

Mount the 21000 housing using the 3/4-14 NPT mounting thread option. Ensure the standoff adapter (2 in) is correctly positioned to achieve the desired probe penetration of 9.5 in. The 0.5 m probe cable must be routed through conduit connections, and the single 3/4-14 NPT plug should be installed in the unused port. Verify that the probe tip is visible for gap setting; the maximum (C)+(D) dimension of 13.5 in (34.3 mm) ensures proper clearance. For intrinsically safe applications, pair with hazardous area approved probes.

Maintenance & Reliability

Inspect the housing assembly periodically for signs of corrosion or mechanical damage, especially in harsh environments. The aluminum body with 304 stainless steel sleeve offers resistance to chemical exposure. Verify O-ring integrity during routine shutdowns to maintain the explosion-proof seal. No internal disassembly is required; focus on external condition and cable connections.

Robust Protection for Critical Vibration Monitoring

When machinery reliability is non-negotiable, the Bently Nevada 21000-28-05-20-095-04-02 proximity probe housing assembly delivers the rugged enclosure and precise sensing needed for continuous vibration monitoring in hazardous environments. Designed for externally mounted proximity probes, this assembly protects the sensor while maintaining accurate gap measurements, reducing unplanned downtime.

Compatibility & Integration

The 21000-28-05-20-095-04-02 is designed for use with Bently Nevada monitoring systems that accept 3300 XL 8 mm proximity probes. The CSA certification covers North American hazardous locations, while RoHS compliance ensures environmental standards are met.

Selection Guide & Purchasing Advice

When selecting a proximity probe housing assembly, confirm that the probe cable length (0.5 m), standoff adapter (2 in), and probe penetration (9.5 in) match your machine geometry. The 3/4-14 NPT mounting thread is standard for many industrial installations. At AutoDCSTech, we offer this Bently Nevada assembly as new and original in factory packing with a 12-month warranty.
