Bently Nevada 21000-28-10-15-050-04-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-28-10-15-050-04-02 are listed below for quick reference:

Installation and Setup Guidance

When mounting the 21000-28-10-15-050-04-02, ensure the 3/4-14 NPT mounting thread is properly sealed to maintain the explosion-proof integrity. The standoff adapter length of 1.5 in (38 mm) positions the probe correctly relative to the shaft. For the 1.0 m cable option, the maximum (C) + (D) dimension with visible probe is 17.0 in (43.18 cm), and the overall maximum is 32.9 in (83.5 cm). Always follow the manufacturer's gap setting procedures to achieve accurate proximity measurements.

Maintenance and Reliability

Regular inspection of the dome cover O-rings and thread seal is recommended to prevent moisture ingress. The aluminum body and stainless steel sleeve resist corrosion, but periodic checks for physical damage or wear on the probe tip are advised. Since the housing is CSA certified, any maintenance must preserve the explosion-proof rating. For best reliability, verify that all conduit connections remain tight and that the probe cable is not stressed at the entry point.

Robust Protection for Critical Vibration Monitoring

For maintenance engineers working in harsh industrial environments, the Bently Nevada 21000-28-10-15-050-04-02 proximity probe housing assembly delivers reliable, continuous vibration monitoring. This component is essential for protecting rotating machinery such as turbines, compressors, and pumps from costly unplanned downtime. Its rugged aluminum body with a 304 stainless steel sleeve withstands corrosive atmospheres and mechanical stress, ensuring long-term sensor integrity.

Engineered for Hazardous Environments

This housing assembly is certified by CSA for explosion-proof applications in North America. It meets Class I Divisions 1 and 2 Groups C and D, Class II Divisions 1 and 2 Groups E, F, and G, and Class III requirements. The enclosure is Type 4 rated, with temperature codes T5 @ Ta = -50°C to +40°C and T4 @ Ta = -50°C to +80°C. These certifications allow safe installation in refineries, chemical plants, and other volatile areas where ignition risks are high.

Compatibility and Integration

This housing assembly is fully compliant with the American Petroleum Institute's (API) 670 Standard for externally mounted proximity probe housings. It works with Bently Nevada 3300 XL 8 mm probes and can be ordered with hazardous area approvals for intrinsically safe applications. The 21000 aluminum housing is designed for use with standard Bently Nevada monitoring systems, ensuring straightforward integration into existing vibration monitoring networks.

Selection Guide and Purchasing Advice

When selecting the 21000-28-10-15-050-04-02, confirm the required probe penetration (5 in) and standoff adapter length (1.5 in) match your machine's geometry. For North American end users, the CA21000 version with CSA certification is available. For other regions, the standard 21000 housing must be ordered.
