Features:

  • Ensures Safe And Reliable Probe Mounting In Hazardous Areas
  • Combines Durable Stainless Steel Construction With Explosion-Proof Fittings
  • Simplifies Installation And Maintenance With Modular Design
The Bently Nevada 24701-28-10-00-040-00-02 Proximity Probe Housing Assembly is designed to securely hold 3300 XL proximity probes while providing explosion-proof protection for hazardous industrial environments. Unlike aluminum housings such as the 21000 series, this assembly uses a full stainless steel body and sleeve, improving corrosion resistance and mechanical strength. Its dual 3/4-14 NPT fittings support CSA-approved conduit connections, enabling safe and straightforward integration into monitoring systems.

The assembly includes a dome cover, threaded ports, optional probe sleeve, O-rings, thread seal, and provisions for reverse-mount probes. Compared to the 164818 stainless steel housing, the 24701 offers greater flexibility in conduit and standoff configurations, making it easier to adapt to varied installation requirements. This modular approach ensures the 3300 XL probe is precisely aligned for accurate proximity sensing while reducing installation complexity.

With a robust design and optional fittings, the Bently Nevada 24701-28-10-00-040-00-02 provides long-term reliability in demanding environments. Its all-metal construction and explosion-proof features make it superior to similar housings like the 21000 and 164818, while maintaining ease of maintenance and adaptability. This combination of durability, safety, and precision positioning makes it a preferred choice for critical machinery monitoring applications.

The 24701-28-10-00-040-00-02 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).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Hardware Attributes: The 24701 is a purely mechanical housing assembly, containing no electronic circuitry, integrated circuits, or programmable components.
  • No Firmware Required: As it does not involve digital signal processing, this product does not have a firmware concept, therefore no software upgrades or firmware updates are required.
  • Physical Maintenance: Its "updates" primarily involve the periodic replacement of mechanical seals (such as O-rings) to maintain the protection rating.
  • This housing is designed for high versatility, accommodating sensors of various sizes: Probe Compatibility: Supports Bently Nevada 3300 XL 8mm series and 7200 5mm/8mm series probes.
  • Cable Connections: Internal space allows for the installation of extension cable connectors and compatibility with standard 1/2-14 NPT or M20x1.5 threaded connections.
  • Thread Specification (-28): Depending on the model code, this component is configured with specific mounting threads (typically 3/4-14 NPT or a specific metric) to accommodate openings in the machine's bearing housing.
  • System Integration: After physically protecting the probe, the raw output signal is directly compatible with all standard monitoring instrument modules such as 3500/42M and 3701/40.
  • External Bearing Housing Monitoring: When it is impossible to install the probe inside the machine, the housing allows observation of the rotating shaft from the outside through the bearing housing.
  • Harsh Environment Protection: Provides a robust physical barrier for precision eddy current probes in environments filled with oil mist, water vapor, high-pressure washing, or chemical corrosion.
  • Easy Gap Adjustment: Allows engineers to easily adjust the probe's mounting gap (Gap Setting) via a cover on the top of the housing without disassembling the machine. Hazardous areas: With the model suffix -02 (certification option), it usually meets explosion-proof standards such as ATEX/IECEx/CSA and is suitable for oil refineries, chemical plants and offshore platforms.
Description
The Bently Nevada 24701-28-10-00-040-00-02 Proximity Probe Housing Assembly is engineered to securely mount 3300 XL 8 mm proximity probes with connector approval options. With a 39-inch (1.0 m) probe cable and a 4.0-inch probe penetration, this assembly ensures precise alignment while maintaining reliable signal transmission. The housing features two 3/4-14 NPT explosion-proof fittings and a robust 303 stainless steel body with a 304 stainless steel sleeve, offering superior resistance to corrosion and harsh industrial environments.

Compared with the 21000 aluminum probe housing assembly and 164818 stainless steel housing, the 24701 assembly delivers enhanced durability and safety. While the 21000 uses aluminum and 164818 offers standard stainless steel, the 24701 combines a full stainless steel construction with threaded explosion-proof fittings, providing improved mechanical strength and CSA-approved protection for hazardous areas. Its design minimizes maintenance and simplifies field installation, making it ideal for critical monitoring applications.

The housing assembly consists of a dome cover, threaded conduit ports, optional probe sleeve, O-rings, reverse mount probe, thread seal, and optional standoff adapter or conduit fittings. These features ensure secure mounting and alignment of the 3300 XL probe while maintaining explosion-proof integrity. The 24701 design supports direct integration into industrial monitoring systems, reducing installation complexity compared with assemblies that require additional components, such as the 21000 and 164818 series.

By combining precise probe alignment, rugged stainless steel materials, and CSA-approved explosion-proof fittings, the Bently Nevada 24701-28-10-00-040-00-02 provides a reliable, maintenance-friendly solution for harsh environments. Its robust construction and standardized fittings make it superior to both the 21000 and 164818 housing assemblies in terms of safety, durability, and installation efficiency.
