Bently Nevada 21000-34-10-30-050-03-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-34-10-30-050-03-02 are listed below for quick reference:

Industry Applications and Failure Prevention

In the oil and gas sector, unplanned downtime from bearing failures can cost millions. The 21000-34-10-30-050-03-02 housing assembly, with its CSA Type 4 enclosure and explosion-proof rating, is designed for continuous operation in Class I, Division 1 hazardous areas. By securely housing the proximity probe, it prevents false readings caused by environmental contamination—a common failure mode in unprotected installations. This assembly is also fully compliant with API 670, ensuring compatibility with standard externally mounted probe configurations used in compressor and turbine monitoring systems.

Installation and Setup Guidance

When installing the 21000-34-10-30-050-03-02, ensure the mounting surface is clean and free of debris. The 3/4-14 NPT thread option (-02) requires a compatible conduit connection. The assembly includes a dome cover, 0-rings, and a thread seal to maintain the enclosure integrity. For hazardous area installations, verify that the probe's hazardous area approval matches the site classification. Use the provided cable seal grip with appropriate grommet size (1/8 to 3/8 inches) to maintain the explosion-proof seal.

Maintenance and Reliability

Periodic inspection of the housing assembly is recommended to ensure the 0-rings and thread seal remain intact. Check for signs of corrosion on the aluminum body and stainless steel sleeve, especially in offshore or chemical environments. The CSA Type 4 rating provides protection against water ingress, but regular visual checks of the conduit fittings and cable grip will extend service life. No internal disassembly is required for routine maintenance.

Robust Protection for Critical Vibration Monitoring

Industrial rotating machinery demands reliable, continuous vibration monitoring to prevent catastrophic failures. The Bently Nevada 21000-34-10-30-050-03-02 proximity probe housing assembly provides a rugged, explosion-proof enclosure for the 3300 XL 8 mm probe, ensuring accurate data collection even in the harshest environments. This assembly is engineered to meet API 670 standards and is CSA certified for hazardous areas, making it a trusted choice for refineries, power plants, and chemical facilities.

Compatibility and Integration

This housing assembly is designed specifically for the 3300 XL 8 mm proximity probe. It includes a reverse mount probe and optional conduit fittings (one 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer). The assembly is compatible with standard Bently Nevada monitoring systems that accept 8 mm probes. For intrinsically safe applications, order the probe with hazardous area approvals to match the housing certification.

Selection Guide and Purchasing Advice

When selecting the 21000-34-10-30-050-03-02, verify the probe penetration (5.0 in) and cable length (1.0 m) meet your installation requirements. AutoDCSTech stocks this assembly as new and original in factory packing, backed by a 12-month warranty. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
