Bently Nevada 31000-16-05-00-063-03-02 English Proximity Probe Housing Assembly

Description

Option 16 (3300 XL 8 mm probe) and Option 02 (3/4-14 NPT mounting thread) specify this English Proximity Probe Housing Assembly configuration — 31000-16-05-00-063-03-02. It provides robust mechanical and environmental protection for the pre-installed proximity probe and its extension cable connection. This external mounting design allows for convenient external probe replacement and gap adjustment from outside the machine casing without requiring disassembly of rotating machinery.

This specific configuration integrates a 3300 XL 8 mm probe with a 0.5 m cable (Option 05) and has a probe penetration length of 6.3 in (Option 063) without a standoff adapter (Option 00). The assembly features a corrosion-resistant glass-reinforced polyphenylene sulfide (PPS) thermoplastic housing base, a stainless steel outer sleeve, and includes one 3/4-14 to 1/2-14 NPT stainless steel reducer alongside a cable seal grip with grommets (Option 03) to establish a highly secure, sealed cable entry.

Features

• Option 16 incorporates an integrated 3300 XL 8 mm proximity probe inside the sleeve assembly.
• Option 05 designates a 0.5 m (20 in) probe cable length for direct extension cable connection.
• Option 00 specifies no standoff adapter, mounting the probe sleeve directly to the machine casing.
• Option 063 provides a precise probe penetration depth of 6.3 in (160 mm) into the machine casing.
• Option 03 includes one 3/4-14 to 1/2-14 NPT stainless steel reducer and a cable seal grip with three grommet sizes.
• Option 02 utilizes a standard 3/4-14 NPT mounting thread for outer sleeve installation.
• Fully compliant with the American Petroleum Institute (API) 670 Standard for external transducer mounting.
• High-strength polyphenylene sulfide (PPS) thermoplastic construction offers excellent chemical and corrosion resistance.

Applications

• Radially mounted proximity probe setups on industrial rotating machinery.
• Shaft radial vibration monitoring and Keyphasor phase reference measurements.
• Protection of proximity probes and connector protectors in harsh oil, gas, steam, and chemical environments.
• Power generation, petrochemical plants, and oil and gas compressor stations requiring external probe casing access.

Installation Guidelines

• Mounting: Mount the outer sleeve directly into the machine case using the 3/4-14 NPT mounting thread (Option 02). Ensure a tight, pressure-resistant seal.
• Cable Routing: Route the probe cable through the provided 3/4-14 to 1/2-14 NPT stainless steel reducer and the cable seal grip using the appropriate sized grommet (1/8 to 3/16, 1/4 to 5/16, or 5/16 to 3/8 inches).
• Sleeve Adjustment: The probe penetration sleeve has an adjustment range of +/-0.5 in (+/-13 mm) to allow precise probe gapping before locking the retaining nut.
• Mechanical Support: If total standoff and penetration lengths exceed 12 in (305 mm), additional sleeve support is recommended near the probe to prevent resonance.
• Torque: Tighten the retaining nut to the recommended torque of 29.4 N-m (260 in-lb) to maintain casing pressure sealing.

Compliance and Certifications

• API 670: Fully compliant with API 670 design requirements for external proximity probe housings.
• Hazardous Areas: Suitable for use in intrinsically safe hazardous area applications when installed with an approved transducer system and appropriate barriers.
• Impact Certification: BASEEFA impact tested (4 Joules at temperature extremes) and CSA impact tested (7 Joules at ambient).
