Bently Nevada 32000-28-10-00-085-03-02 Metric Proximity Probe Housing

Robust Protection for Critical Machinery Monitoring

For maintenance engineers tasked with ensuring uptime of rotating assets, the Bently Nevada 32000-28-10-00-085-03-02 offers a durable, field-proven solution for proximity probe mounting. This metric housing is engineered to withstand extreme conditions while maintaining precise sensor alignment, reducing false trips and unplanned downtime.

Key Features and Construction

Built with a glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic containing conductive fibers, the housing provides chemical resistance and electrostatic dissipation. The sleeve and retaining chain are AISI 304 stainless steel, while the outer sleeve and exterior screws use AISI 303 stainless steel for corrosion resistance. A Neoprene® O-ring ensures a reliable seal.

Technical Specifications Breakdown

Key parameters for the 32000-28-10-00-085-03-02 are listed below for quick reference:

Industry Applications

The IP66 and Type 4X ratings allow installation in washdown areas or outdoor locations exposed to rain and dust. The 85 mm penetration option suits machines with thicker casings, ensuring the probe tip reaches the target shaft without interference.

Installation and Setup Guidance

When installing, ensure the 3/4-14 NPT mounting thread is properly sealed to maintain the enclosure rating. Use the supplied M20 fitting and cable seal grip for armored probe cable entry. The two plugs seal unused ports. Verify the probe cable length (1.0 m) is sufficient for routing to the junction box without strain. Torque fittings to manufacturer recommendations to avoid housing cracking.

Maintenance and Reliability

Periodically inspect the housing for cracks, especially after impact events. The housing has been certified to withstand 4 Joule impacts at extreme temperatures, but physical damage can compromise the seal. Check the Neoprene O-ring for degradation during annual overhauls. Clean the exterior with mild soap and water; avoid solvents that may attack PPS.

Selection Guide and Purchasing Advice

When selecting a replacement or new housing, confirm the probe penetration (85 mm) and mounting thread (3/4-14 NPT) match your application. The 32000-28-10-00-085-03-02 includes a 3300 XL 8 mm probe with multiple approvals, making it suitable for hazardous areas with proper certification.
