Bently Nevada 31000-28-10-00-017-00-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 31000-28-10-00-017-00-02 are listed below for quick reference:

Industry Applications

Typical installations include:

• Steam and gas turbines in power generation: The IP66 and Type 4X rating protects against hose-directed water and dust ingress, ensuring reliable vibration monitoring in washdown areas.
• Compressors and pumps in petrochemical facilities: The CENELEC EN50014 rating for electrostatic dissipation of plastic material in hazardous areas allows safe use in explosive atmospheres. The -51°C to +105°C temperature range accommodates extreme process conditions.
• Large rotating machinery in pulp and paper mills: The glass-reinforced PPS housing with conductive fibers provides both mechanical strength and static discharge, while the AISI 304/303 stainless steel sleeve and hardware resist corrosion from moisture and chemicals.

Installation & Setup Guidance

Proper installation ensures the probe housing maintains its environmental seal and mechanical integrity. Follow these engineer-level guidelines:

• Mounting thread: Use the 3/4-14 NPT thread option (required when no standoff adapter is selected). Apply thread sealant compatible with Neoprene O-rings to prevent leaks.
• Torque specification: Tighten the retaining nut to 29.4 N·m (260 in·lb) using a calibrated torque wrench. Overtightening may damage the PPS housing; undertightening can compromise the seal.
• Probe insertion: The 1.7 in probe penetration (option 017) positions the 3300 XL 8 mm probe tip correctly relative to the shaft. Verify the probe cable length of 1.0 in (option 10) matches your routing requirements.
• Grounding: The housing's conductive fibers provide electrostatic dissipation. Ensure the mounting surface is electrically bonded to the system ground per CENELEC EN50014 requirements.
• Seal integrity: The internal Viton O-ring on the probe case and the Neoprene O-ring between sleeve and housing create the pressure seal. Do not subject the assembly to internal or external pressure; it is designed only for differential pressure sealing.

Maintenance & Reliability

Regular inspection of the probe housing assembly maximizes uptime and prevents false readings:

• Visual inspection: Check the housing and cover for cracks, deformation, or corrosion every 6 months. Pay special attention to the O-ring sealing surfaces.
• Environmental check: Verify that the Type 4X and IP66 ratings are maintained by ensuring all fasteners are tight and the cover gasket is clean and undamaged.
• Impact damage: After any mechanical impact, inspect the housing for signs of damage. The housing is certified to withstand 4 Joule impacts at extreme temperatures and 7 Joule at ambient, but repeated impacts may degrade performance.
• Torque verification: Re-torque the retaining nut to 29.4 N·m during scheduled maintenance to compensate for thermal cycling and vibration loosening.

Robust Protection for Critical Vibration Monitoring

Industrial rotating machinery demands reliable vibration monitoring to prevent catastrophic failures. The Bently Nevada 31000-28-10-00-017-00-02 proximity probe housing assembly provides a rugged, sealed enclosure designed specifically for 3300 XL 8 mm proximity probes. This component ensures accurate, continuous measurement of shaft vibration and position in harsh environments, including hazardous areas with electrostatic dissipation requirements.

Compatibility & Integration

The 31000-28-10-00-017-00-02 is specifically designed for use with the Bently Nevada 3300 XL 8 mm proximity probe system.

• 3300 XL 8 mm probes (option 28) with multiple agency approvals for global installations.
• Bently Nevada monitoring systems that accept standard proximity probe inputs (e.g., 3500, 3300, and 1701 series racks).
• Hazardous area installations requiring CENELEC EN50014 electrostatic dissipation rating for plastic enclosures.

Selection Guide & Purchasing Advice

When selecting the correct probe housing, verify that the part number 31000-28-10-00-017-00-02 matches your probe type, cable length, penetration depth, and mounting thread requirements. The 3/4-14 NPT thread is mandatory when no standoff adapter is used. For applications requiring pressure testing of the seal, contact Bently Nevada's custom design department.
