Bently Nevada 21000-28-05-00-096-03-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-28-05-00-096-03-02 are listed below for quick reference:

Industry Applications

Refinery and Petrochemical Vibration Monitoring

In refineries, where flammable gases and dusts are present, the 21000-28-05-00-096-03-02 provides a certified explosion-proof solution. Its CSA Type 4 enclosure and T4/T5 temperature ratings allow safe operation in Class I, Division 1 areas. The 304 stainless steel sleeve resists corrosion from hydrogen sulfide and other aggressive chemicals, ensuring long-term reliability.

Power Generation Turbine Protection

Steam and gas turbines require precise shaft vibration measurement. The 9.6-inch probe penetration accommodates deep casing installations, while the 0.5 m cable length simplifies routing to junction boxes. The aluminum body with stainless steel sleeve minimizes thermal expansion effects, maintaining consistent gap voltage over temperature swings.

Installation and Setup Guidance

Mount the housing using the 3/4-14 NPT thread into a suitable port on the machine casing. Ensure the probe tip is positioned per the manufacturer's gap setting procedure. Use the provided 3/4-14 to 1/2-14 NPT reducer if conduit size requires adaptation. The cable seal grip accommodates cables from 1/8 to 3/8 inches; select the appropriate grommet to maintain environmental seal integrity. Always route cables away from high-temperature surfaces and sharp edges.

Maintenance and Reliability

Periodically inspect the housing for signs of corrosion, especially in coastal or chemical environments. Verify that the dome cover and conduit fittings remain tight to preserve the explosion-proof rating. The O-rings should be replaced if any leakage path is suspected. No internal disassembly is required for routine inspection; focus on external condition and cable integrity.

Robust Protection for Critical Vibration Monitoring

In rotating machinery monitoring, probe housing failure can lead to inaccurate readings and unplanned downtime. The Bently Nevada 21000-28-05-00-096-03-02 proximity probe housing assembly addresses this challenge by providing a durable, explosion-proof enclosure for the 3300 XL 8 mm probe. Designed for harsh industrial environments, this assembly ensures reliable vibration data acquisition while protecting sensitive components from contaminants and mechanical damage.

Compatibility and Integration

This assembly is designed for use with Bently Nevada 3300 XL 8 mm proximity probes and compatible monitors (e.g., 3500 series). The CSA certification ensures compliance with North American hazardous location requirements. The housing meets API 670 standards for externally mounted proximity probes, making it suitable for retrofit on existing machinery.

Selection Guide and Purchasing Advice

When ordering the 21000-28-05-00-096-03-02, verify that the probe penetration (9.6 in) and cable length (0.5 m) match your installation requirements. If a standoff adapter is needed, specify a non-zero suffix code. For North American end users, consider the CA21000 variant for additional certifications.
