  • Condition New Original ready stock
  • Product Family 21000-28-10-00-098-04-10,21000-28-20-00-098-04-02,21000-28-10-00-098-04-05
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.
  • Online Adjustment Capability: Allows for precise adjustment of the probe gap during machine operation (via an external cable seal), greatly improving maintenance efficiency without downtime.
  • Probe Protection: Provides a robust physical barrier for 8 mm and 5 mm eddy current probes, preventing environmental contaminants from interfering with measurements.
  • Standardized Connections: This configuration (-04-02) typically includes 3/4-14 NPT conduit connections and a standard external terminal box, ensuring high signal integrity.
  • Mechanical Stability: The aluminum housing (-28 code indicates aluminum) provides lightweight construction while ensuring the rigidity of the probe holder under long-term vibration.
  • Large Rotating Machinery: Widely used in steam turbines, gas turbines, centrifugal compressors, and large pumps.
  • External Bearing Housing Mounting: When it is not possible to mount the probe inside the machine, this housing is mounted externally, with the probe extending through mounting holes to monitor shaft vibration.
  • Oil and Chemical Facilities: Used in critical production lines requiring frequent probe gap calibration or preventative maintenance.
  • Multi-parameter Monitoring: Often installed in pairs (X-Y direction) for axis trajectory analysis.
  • Enclosure Material: ADC12 die-cast aluminum (code -28) with an epoxy resin coating for excellent resistance to atmospheric corrosion.
  • Hazardous Area Certification: Compliant with ATEX/IECEx and North American (CSA/NRTL) certifications, suitable for flammable and explosive environments such as Zone 0, 1, or 2 (depending on the internally installed probe and safety barrier configuration).
  • Protection Rating: The enclosure is typically designed to IP66 or Type 4X rating, effectively protecting against rain, spray, and dust intrusion.
  • Temperature Resistance: The mechanical components can withstand a typical wide industrial temperature range (typically -40°C to +100°C), with the upper limit limited by the internally installed probe and seals.
Description
Bently Nevada 21000-28-10-00-098-04-02 Proximity Probe Housing Assembly is engineered for robust external mounting of 3300 XL 8mm probes with selectable hazardous area approvals. Unlike the compact 164818 housing, this assembly provides a full aluminum body with 304 stainless steel sleeve, allowing optimal protection and longevity in industrial applications. The assembly includes one 3/4-14 NPT plug and matching mounting thread, providing secure and reliable installation.

Compared to the 24701 stainless steel housing, the 21000 aluminum housing offers lighter weight while maintaining CSA Type 4 certification and compliance with API 670 standards. Its dome cover screws directly into the housing body, and threaded ports support conduit connections, making it easier to integrate with existing systems. Optional standoff adapters and conduit fittings allow flexible configurations that adapt to space restrictions, though the 21000 excels in standard installations without requiring additional accessories.

The probe penetration option of 9.8 inches ensures precise placement, while the probe cable length of 1.0 m (39 in) provides sufficient lead length for most mounting locations. Sleeve lengths exceeding 304 mm (12 in) can be supported with Bently Nevada’s probe support and oil seal (37948-01), which helps reduce vibration for long-sleeve installations. In contrast, the 164818 Compact Proximity Probe Housing is better suited for highly restricted spaces but offers less flexibility in sleeve support.

Bently Nevada 21000-28-10-00-098-04-02 is designed for intrinsically safe applications, making it compatible with both standard and hazardous area installations. The combination of aluminum body and stainless steel sleeve ensures resistance to corrosion and wear, outperforming standard 24701 housings in ease of installation and maintenance. This assembly provides an ideal solution for applications requiring high reliability, long service life, and compliance with safety certifications.
