Bently Nevada 21000-00-00-00-00--03-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

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

Industry Applications

• Refinery Turbomachinery Monitoring: The housing meets API 670 standards for externally mounted proximity probes, ensuring reliable vibration data collection on critical rotating equipment like compressors and turbines.
• Chemical Plant Pump Protection: Explosion-proof certification allows safe installation in Divisions 1 and 2 areas where flammable gases or vapors may be present.
• Power Generation Steam Turbines: The wide temperature range (T5 @ Ta = -50°C to +40°C, T4 @ Ta = -50°C to +80°C) supports operation in extreme ambient conditions.

Installation and Setup Guidance

When installing the housing, ensure the mounting thread option matches your conduit system. The 03 option includes a 3/4-14 NPT fitting, a reducer to 1/2-14 NPT, and a cable seal grip with grommets for cable diameters from 1/8 to 3/8 inches. For standoff adapter use, select the 02 option with 3/4-14 NPT threads. The probe sleeve length is determined by the probe penetration specification; this unit is configured with 0.0 inches penetration. Always follow the manufacturer's wiring diagram (drawing 140979) to maintain non-incendive circuit compliance.

Designed for Hazardous Area Reliability

This housing assembly is built for long-term service in harsh industrial environments. The aluminum body resists corrosion while the 304 stainless steel sleeve provides durability at the probe interface. With CSA Type 4 enclosure rating and explosion-proof certification, the 21000-00-00-00-00--03-02 is suitable for Class I and Class II hazardous locations, making it a trusted choice for refineries, chemical plants, and gas processing facilities.

Maintenance and Reliability

Periodically inspect the housing for signs of corrosion or damage to the O-rings and thread seal. Verify that the cable seal grip grommets remain intact to preserve the explosion-proof integrity. The CSA certification requires that all conduit fittings and seals be maintained per local codes. No internal disassembly is recommended; routine external inspection is sufficient.

Robust Protection for Critical Vibration Monitoring

For maintenance engineers working in hazardous environments, the Bently Nevada 21000-00-00-00-00--03-02 proximity probe housing assembly provides a reliable, certified solution for externally mounted proximity probes. This aluminum housing with a 304 stainless steel sleeve is engineered to meet the demanding requirements of API 670 Standard, ensuring consistent performance in vibration monitoring applications.

Compatibility and Integration

This housing assembly is designed for use with Bently Nevada proximity probes and systems. It is fully compliant with API 670 Standard for externally mounted proximity probe housings. The CSA certification covers both the 21000 aluminum and 24701 stainless steel housings for intrinsically safe applications when ordered with approved probes.

Selection Guide and Purchasing Advice

When selecting a housing, verify your required mounting thread option, probe cable length, and standoff adapter needs. The 21000-00-00-00-00--03-02 is configured with no probe, no cable, no standoff adapter, and no fittings, making it a flexible base unit.
