          The BENTLY NEVADA 21000-34-10-20-062-04-02 uses the -34 probe option, which specifies a 3300 XL 8 mm proximity probe with connector protector and multiple approvals. The assembly is supplied with the -10 probe cable option, providing a 1.0 m (39 in) integral probe cable suitable for standard machinery installations.

          The BENTLY NEVADA 21000-34-10-20-062-04-02 includes the -20 option, indicating a 2.0-inch standoff adapter, together with the -062 probe penetration option, providing 6.2 inches of probe penetration. This configuration allows the proximity probe to be positioned accurately through machine casings while maintaining the required measurement gap for reliable shaft vibration and position monitoring.

          The BENTLY NEVADA 21000-34-10-20-062-04-02 is supplied with fittings option -04, consisting of one 3/4-14 NPT plug only, while the -02 suffix specifies a 3/4-14 NPT mounting thread. When a standoff adapter is selected, the 3/4-14 NPT mounting thread is required as part of the assembly configuration.

          Features:

          • All‑metal aluminum alloy housing construction
          • Hazardous area explosion‑proof certifications
          • API 670 compliance
          • Wide operating temperature range
          The Bently Nevada 21000‑34‑10‑20‑062‑04‑02 Proximity Probe Housing Assembly is a fully metallic, explosion‑proof housing for externally mounted proximity probes. The 21000 series housing is constructed with an aluminum alloy body and a 304 stainless steel probe sleeve, achieving a lightweight without compromising strength. The assembly consists of a cap, threaded conduit opening, optional probe sleeve length, O‑ring, reverse‑mount proximity probe, thread sealant, and optional conduit fitting and mounting adaptor.

          In terms of safety certifications, the 21000 housing carries CSA explosion‑proof approval for Class I Divisions 1 and 2 Groups C and D, Class II Divisions 1 and 2 Groups E/F/G, and Class III hazardous areas, with a Type 4 enclosure rating. The 21000 also fully complies with the externally mounted proximity probe housing requirements of API Standard 670. For North American users, a CSA‑certified version designated CA21000 (a variant of the 21000) is available to meet local regulatory needs.

          The 21000‑34‑10‑20‑062‑04‑02 Bently Nevada Proximity Probe HousingAssemblies may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.
          The 21000 features an adjustable probe penetration with an adjustment range of 13 mm (±0.5 in), providing installation flexibility to achieve the correct gap between the probe tip and the target material. For the 21000, sleeve length is determined by the installation location, and the probe lead must be longer than the sleeve to ensure proper cable routing and connectivity.
          For installations requiring sleeve lengths greater than 304 mm (12 in), the 21000 requires additional sleeve support near the probe to prevent resonance from occurring. Bently Nevada offers a probe support and oil seal (part number 37948-01) for use with the 21000 when long sleeves must pass through an inner bearing housing, and custom sleeve lengths can also be manufactured to meet specific application needs.
          The 21000 is configured using the ordering format 21000-AA-BB-CC-DDD-EE-FF, allowing selection of probe type, sleeve length, conduit fittings, and mounting thread options. This modular ordering approach ensures the 21000 can be precisely tailored to match the mechanical and environmental requirements of each installation.
