Features:

  • Constructed With High-Grade Stainless Steel For Maximum Durability
  • Supports Precise Probe Positioning With Adjustable Sleeve And Standoff
  • CSA-Approved For Hazardous Areas And Compliant With API 670 Standards
The Bently Nevada 24701-28-05-05-064-03-02 Proximity Probe Housing Assembly provides a robust solution for externally mounting 3300 XL 8mm proximity probes with approval options. Its 303 stainless steel body and 304 stainless steel sleeve ensure superior resistance to corrosion and mechanical stress, offering enhanced reliability compared with aluminum housings like the 21000 series.

This assembly features a 20 in (0.5 m) probe cable, a 0.5 in standoff adapter (Option C), and a 6.4 in probe penetration (Option D), providing flexible installation options even in compact or vibration-prone environments. Compared with the 164818 compact housing, the 24701-28-05-05-064-03-02 allows standard sleeve lengths to be supported without additional vibration issues, and optional supports are available for longer sleeves exceeding 12 inches.

The housing includes one 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer, and cable seal grips for 1/8 to 3/8 inch cables. It mounts via 3/4-14 NPT threading and is CSA-approved for hazardous areas, meeting explosion-proof requirements and API 670 compliance. With integrated O-rings, dome cover, reverse mount probe, threaded ports, and optional conduit fittings, the 24701-28-05-05-064-03-02 assembly provides a complete, reliable, and flexible solution for industrial proximity monitoring applications.

The 24701-28-05-05-064-03-02 Bently Nevada Proximity Probe Housing Assemblies may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Corrosive Environment Monitoring: Constructed from 303/304 stainless steel, it is specifically designed for environments with salt spray or acidic gases, such as offshore oil platforms, chemical plants, or paper mills.
  • Small to Medium-Sized Bearing Housings: A 6.4-inch (approximately 162mm) penetration depth is suitable for installation on pumps, fans, or gearboxes with moderate housing thickness.
  • API 670 Standard Applications: Used for monitoring radial vibration or axial thrust in large rotating machinery, allowing for external adjustment of the probe gap or replacement during machine operation.
  • Explosion-Proof Rating: This series (especially versions with the CA24701 prefix) is CSA/NRTL/C certified and suitable for Class I, Division 1 & 2 (Zone 1 & 2) hazardous areas. Its physical structure is designed for explosion-proof protection.
  • Industry Standard: Fully compliant with API 670 5th Edition specifications for non-contact displacement sensor mounting housings.
  • Protection Rating: Provides NEMA 4/IP66 level sealing protection to prevent moisture and contaminants from entering the machine or damaging the probe.
  • Material Reliability: Stainless steel construction ensures mechanical stability at extreme temperatures (-51°C to +177°C).
  • Internal Physical Connection: The housing houses the 3300 XL 8mm reverse-mount probe, connected via its 0.5-meter coaxial cable.
  • Cable Outlet: Connects to a flexible metal conduit via a 3/4-14 NPT threaded connector, protecting the extension cable.
  • Transmitter Docking: The signal is transmitted via the extension cable to the 3300 XL Proximitor sensor, converting gap changes into a 200 mV/mil (or 7.87 V/mm) voltage signal.
  • System Integration: This voltage signal is ultimately connected to the Bently Nevada 3500 monitoring system or the Orbit 60 series to achieve real-time data display, alarm, and logic tripping.
Description
The Bently Nevada 24701-28-05-05-064-03-02 Proximity Probe Housing Assembly is designed for precise external mounting of 3300 XL 8mm proximity probes with approval options, providing superior durability and compliance for industrial monitoring. Its 303 stainless steel body and 304 stainless steel sleeve deliver long-lasting corrosion resistance and mechanical strength, outperforming aluminum assemblies like the 21000 in harsh environments.

This assembly features a 20 in (0.5 m) probe cable, a 0.5 in standoff adapter (Option C), and a 6.4 in probe penetration (Option D), enabling accurate probe placement even in compact machinery. Compared with the 164818 compact housing, the 24701-28-05-05-064-03-02 supports standard sleeve lengths without compromising vibration stability, and optional sleeve supports are available for longer installations.

The housing includes one 3/4-14 NPT plug, a 3/4-14 to 1/2-14 NPT reducer, and a cable seal grip with grommets compatible with cable diameters from 1/8 to 3/8 inches. It mounts using 3/4-14 NPT threads and is fully CSA-approved for hazardous areas, rated explosion-proof, and compliant with API 670 standards. Compared with the 21000 aluminum or 164818 compact housings, the 24701-28-05-05-064-03-02 provides stronger construction, versatile fittings, and flexible sleeve options, making it ideal for both standard and intrinsically safe installations.

Bently Nevada also offers additional accessories such as probe supports and oil seals (part number 37948-01) for long sleeves that pass through inner bearing housings. Custom sleeve supports are available to further reduce vibration on unsupported long sleeves, ensuring stable and reliable probe readings over time.

The 24701-28-05-05-064-03-02 housing integrates all essential components, including O-rings, dome covers, threaded ports, reverse mount probes, and optional conduit fittings, providing a complete, ready-to-install solution for industrial proximity monitoring. Its compatibility with CSA-approved 21000 and 164818 series housings allows for flexible application selection while maintaining consistent reliability and performance.
