Bently Nevada 21000-34-00-15-065-03-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-34-00-15-065-03-02 are listed below for quick reference:

Industry Applications

• Refineries and Petrochemical Plants: Monitor shaft vibration in pumps, compressors, and turbines operating in explosive atmospheres.
• Power Generation: Protect vibration probes on steam turbines and generators. The 1.5 in standoff adapter and 6.5 in probe penetration allow precise positioning within the machine casing.
• Oil and Gas Pipelines: Reliable operation on critical rotating equipment in remote or harsh environments. The included NPT fittings and cable seal grip simplify installation and maintain enclosure integrity.

Installation and Setup Guidance

When installing the 21000-34-00-15-065-03-02, ensure the mounting thread (3/4-14 NPT) matches the machine port. The standoff adapter (1.5 in) and probe penetration (6.5 in) determine the probe tip gap. Use the provided fittings: one 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer, and the cable seal grip with grommets for cable sizes 1/8 to 3/16 inches, 1/4 to 5/16 inches, or 5/16 to 3/8 inches. Tighten all connections to maintain the explosion-proof seal.

Maintenance and Reliability

Inspect the housing assembly periodically for signs of corrosion, damage, or loose fittings. Verify that the cable seal grip grommets remain pliable and provide a tight seal. The 0-rings inside the assembly should be checked during probe replacement. No disassembly of the housing is required for routine inspection.

Robust Protection for Critical Vibration Monitoring

Industrial rotating machinery demands reliable vibration monitoring. The Bently Nevada 21000-34-00-15-065-03-02 proximity probe housing assembly provides a rugged, sealed enclosure for 3300 XL 8 mm probes in demanding environments. This assembly protects the probe from physical damage, moisture, and contaminants, ensuring consistent, accurate measurements.

Engineered for Hazardous Environments

This housing is rated explosion proof for hazardous areas and carries Canadian Standards Association (CSA) approvals. It is certified as a CSA Type 4 enclosure and fully complies with API 670 Standard for externally mounted proximity probe housings. The aluminum body and 304 stainless steel sleeve provide corrosion resistance and mechanical strength.

Compatibility and Integration

This housing is designed for use with Bently Nevada 3300 XL 8 mm proximity probes with connector protector. The probe cable length option "00" indicates that the probe cable is not required; ensure the probe itself has an integral cable of appropriate length (1.0 m as specified). The assembly accepts probes with visible part number and serial number up to a maximum (C) + (D) dimension of 17.0 in (43.18 cm), with overall maximum (C) + (D) of 32.9 in (83.5 cm).

Selection Guide and Purchasing Advice

When ordering, verify the standoff adapter length and probe penetration match your machine geometry.
