Overview Manuals Specifications Compatibility Application Scenarios Upgrades

Features:

  • Provides external access for probe adjustment and replacement without dismantling machinery.
  • Complete conduit fitting package supports multiple cable diameters for installation flexibility.
  • CSA Type 4 enclosure design with API 670 compliance and explosion-proof configuration availability for hazardous environments.
21000-34-05-00-022-03-02 is intended for industrial rotating machinery where reliable proximity probe mounting and maintenance accessibility are important. External installation reduces maintenance complexity while helping technicians perform inspection and probe servicing with minimal equipment disruption. The aluminum housing offers a practical solution for monitoring systems operating in demanding industrial environments. Compatibility with the 3300 XL 8 mm probe further extends its application across machinery protection systems.

The housing assembly integrates several mechanical components into a single package, including the housing body, dome cover, probe sleeve, seals, fittings, and mounting hardware. Different cable grommets accommodate multiple cable diameters, allowing installers to select the appropriate sealing arrangement during commissioning. The specified 3/4-14 NPT mounting thread supports secure installation where no standoff adapter is required. A 2.2-inch probe penetration is provided for the configured assembly.

Many industrial facilities require equipment capable of operating in hazardous or regulated environments. 21000-34-05-00-022-03-02 supports these requirements through CSA-approved explosion-proof housing options and compatibility with intrinsically safe proximity probes. Compliance with API 670 also makes the assembly appropriate for machinery protection systems commonly used in oil and gas, power generation, petrochemical, and other continuous-process industries.

The 21000-34-05-00-022-03-02 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 21000-34-05-00-022-03-02 belongs to the 21000 aluminum proximity probe housing assembly series for externally mounted proximity probes. The assembly includes a dome cover that screws into the housing body, threaded conduit ports, a probe sleeve, O-rings, a reverse mount proximity probe, a thread seal, optional conduit fittings, and mounting components. The supplied configuration features a 3300 XL 8 mm probe with connector protector and multiple approvals, making the assembly suitable for demanding industrial installations.

The configuration provides a 2.2 in. probe penetration without a standoff adapter and uses a 3/4-14 NPT mounting thread. Fittings include one 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer, and one cable seal grip with interchangeable grommets for cable diameters ranging from 1/8 to 3/16 in., 1/4 to 5/16 in., and 5/16 to 3/8 in. This arrangement simplifies conduit connection while supporting different cable sizes in a single installation.

A major advantage of 21000-34-05-00-022-03-02 is the ability to access the probe and extension cable externally, making routine gap adjustment or probe replacement possible without machine disassembly. Both the 21000 aluminum and 24701 stainless steel housing assemblies are available in CSA-approved explosion-proof versions for hazardous locations, while CSA and BASEEFA approved proximity probes can also be ordered for intrinsically safe applications. The housing complies with CSA Type 4 enclosure requirements and fully meets the requirements of API 670 for externally mounted proximity probe housings. For sleeve lengths exceeding 304 mm (12 inches), additional sleeve support is recommended to minimize vibration caused by unsupported long sleeves.
