Features:

  • Combines an aluminum housing body with a 304 stainless steel sleeve for reliable mechanical protection and corrosion resistance.
  • Certified as a CSA Type 4 enclosure with explosion-proof and hazardous area approvals while complying with API 670 requirements.
  • Includes a complete installation package featuring conduit fittings, cable seal grip, interchangeable grommets, reverse mount probe, and threaded mounting components.
Bently Nevada 21000-32-05-00-038-03-02 supports external mounting of proximity probes used in continuous machinery condition monitoring. The housing protects the probe while providing a stable mounting arrangement in industrial installations. Its rugged construction makes it suitable for rotating equipment operating in demanding environments. The assembly also helps simplify installation by integrating essential mounting components into a single package. Such a configuration is valuable in oil and gas, power generation, and process control facilities.

The housing accommodates a 3300 XL NSv probe equipped with a connector protector and a 0.5 m cable. A 3.8-inch probe penetration allows the sensing element to reach the required measurement position without requiring a standoff adapter. Multiple conduit fittings and cable grommets provide flexibility for different cable diameters encountered during field installation. These features contribute to a practical installation process while maintaining cable protection.

Bently Nevada 21000-32-05-00-038-03-02 is intended for hazardous area installations where certified protection and dependable probe positioning are essential. Compliance with CSA Type 4 and API 670 standards supports use in critical machinery monitoring systems. Additional sleeve support can be incorporated whenever long sleeve installations are required, helping reduce vibration and maintain measurement stability. The result is a robust housing assembly that complements vibration and shaft position monitoring applications across industrial plants.

The 21000-32-05-00-038-03-02 Bently Nevada Proximity Probe Housing Assembly may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
Bently Nevada 21000-32-05-00-038-03-02 is a proximity probe housing assembly built for the external installation of 3300 XL NSv proximity probes. The assembly features an aluminum housing body with a 304 stainless steel sleeve, creating a durable structure for industrial environments. A reverse mount proximity probe, dome cover, threaded conduit ports, O-rings, thread seal, and optional conduit fittings are incorporated into the complete housing assembly. The mounting interface uses a 3/4-14 NPT thread, making installation suitable for a wide range of rotating machinery applications.

The probe supplied with 21000-32-05-00-038-03-02 includes a connector protector together with selectable hazardous area approvals. A 0.5 m (20 in) probe cable is provided, while the housing is configured without a standoff adapter. The probe penetration dimension is 3.8 inches, allowing the assembly to accommodate the required installation depth. The fitting package contains one 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer, and one cable seal grip with interchangeable grommets designed for cable diameters of 1/8 to 3/16 inches, 1/4 to 5/16 inches, and 5/16 to 3/8 inches.

For hazardous locations, 21000-32-05-00-038-03-02 is available with Canadian Standards Association approvals and is rated explosion proof for hazardous areas. When paired with hazardous area approved proximity probes, the aluminum housing supports intrinsically safe applications. The enclosure is certified as a CSA Type 4 housing and fully complies with the American Petroleum Institute (API) 670 Standard for externally mounted proximity probe housings, making it suitable for demanding process industries.

Proper sleeve selection remains important for reliable operation. Sleeve length should match the installation location, and the probe lead must always be longer than the sleeve. Sleeve lengths exceeding 304 mm (12 inches) require additional sleeve support to minimize vibration caused by unsupported extensions. Bently Nevada offers probe support and oil seal part number 37948-01 for long sleeves passing through an inner bearing housing, while custom sleeve supports are also available for specialized installations. The 21000-32-05-00-038-03-02 therefore provides a dependable mounting solution for long-term machinery monitoring.
