Bently Nevada 31000-16-05-30-050-02-02 English Proximity Probe Housing Assembly

Description

The 31000-16-05-30-050-02-02 is an English Proximity Probe Housing Assembly configuration featuring a 3300 XL 8 mm proximity probe (Option 16), a 0.5 m probe cable (Option 05), and a 3/4-14 NPT mounting thread (Option 02). This assembly is designed for the protection and mounting of eddy-current displacement transducers, allowing for external access to the proximity probe and its extension cable. This configuration supports gap adjustment and probe replacement without requiring the disassembly of the machine case, ensuring efficient maintenance cycles for rotating machinery.

Constructed from polyphenylene sulfide (PPS) and corrosion-resistant stainless steel, this housing assembly meets the mechanical and environmental protection requirements for harsh industrial environments. The 31000 series is fully compliant with API 670 standards for externally mounted proximity probe housings. This specific unit includes two M25 conduit fittings and one plug (Option 02 for Fittings), providing robust connectivity options for standard monitoring installations.

Features

• Integrated 3300 XL 8 mm proximity probe (Option 16) for radial vibration or axial position measurement
• Includes 0.5 m probe cable length (Option 05)
• Standoff adapter (Option 30) for mounting clearance
• Probe penetration depth of 50 mm (Option 050)
• Fittings configuration: Two M25 fittings, one plug (Option 02)
• Mounting thread: 3/4-14 NPT (Option 02)
• High-strength, corrosion-resistant PPS (polyphenylene sulfide) housing material
• Compliant with API 670 standards for machine case proximity probe mounting

Applications

• Radial vibration monitoring on large rotating machinery
• Keyphasor and speed measurements
• Axial position monitoring
• Hazardous area applications (when used with approved transducer systems and I.S. barriers)
• Petrochemical and power generation turbine monitoring

Installation Guidelines

Ensure the machine casing is securely affixed to the bearing to maintain accurate relative vibration signals. When installing, insert the probe sleeve into the machine case and adjust the probe gap before fitting the housing. All hole plugs, if used, must be tightened to 0.5 N-m (5 in-lbs) to maintain environmental seal integrity. Ensure correct routing of the extension cable through the M25 fittings to prevent strain on the connector.

Compliance and Certifications

The 31000 housing assembly complies with API 670 standards. For hazardous area applications, ensure this housing is used in conjunction with a certified transducer system and the appropriate intrinsic safety barriers as specified in the Bently Nevada Approvals Quick Reference Guide (108M1756).
