Technical Specifications Breakdown

Key parameters for the 21000-28-10-20-095-04-02 are listed below for quick reference:

Industry Applications for the 21000 Assembly

This housing assembly is designed for externally mounted proximity probes on critical rotating equipment such as turbines, compressors, and pumps. The 9.5 in probe penetration allows installation through thick machine casings, while the 2 in standoff adapter positions the probe tip accurately. The CSA Type 4 enclosure and explosion-proof rating (Class I Divisions 1 and 2 Groups C and D, Class II Divisions 1 and 2 Groups E, F, and G) make it suitable for hazardous areas in oil and gas, petrochemical, and power generation facilities. By using a certified assembly, engineers reduce the risk of false trips and improve machine reliability.

Installation and Setup Guidance

When installing the 21000-28-10-20-095-04-02, ensure the mounting surface is clean and flat. Use the 3/4-14 NPT mounting thread (option 02) for a secure fit. The one 3/4-14 NPT plug (fitting option 04) seals unused conduit ports. Route the 1.0 m probe cable carefully to avoid sharp bends. The standoff adapter (20=2 in) must be installed to achieve the correct probe gap. Always follow the manufacturer's guidelines for probe gap setting and cable routing to maintain signal integrity.

Maintenance and Reliability

Periodically inspect the housing for signs of corrosion or damage, especially in harsh environments. The aluminum body with 304 stainless steel sleeve offers good corrosion resistance, but regular visual checks are recommended. Verify that all O-rings and seals are intact to maintain the explosion-proof rating. The CSA certification requires that any replacement parts match the original specifications. For long-term reliability, keep the assembly clean and ensure conduit connections remain tight.

Robust Protection for Critical Vibration Monitoring

For maintenance engineers working with rotating machinery, reliable vibration monitoring is non-negotiable. The Bently Nevada 21000-28-10-20-095-04-02 proximity probe housing assembly provides a rugged, certified enclosure for the 3300 XL 8 mm probe in demanding environments. This assembly simplifies installation and ensures consistent, accurate measurements.

Compatibility and Integration

This housing assembly is designed specifically for the Bently Nevada 3300 XL 8 mm proximity probe. The 21000 model is compatible with Bently Nevada monitoring systems that accept 8 mm probes. The assembly includes a reverse mount proximity probe and a thread seal, simplifying integration. For intrinsically safe applications, order hazardous area approved probes with this housing. The assembly complies with API 670 Standard for externally mounted proximity probe housings.

Selection Guide and Purchasing Advice

When selecting a proximity probe housing, consider the probe penetration depth and cable length required for your machine. The 21000-28-10-20-095-04-02 is a specific configuration with a 9.5 in penetration and 1.0 m cable. If your application needs a different standoff adapter or cable length, consult the Bently Nevada ordering guide.
