Bently Nevada 31000-00-00-00-000-00-00 English Proximity Probe Housing Assemblies

Description

The 31000-00-00-00-000-00-00 is an English Proximity Probe Housing Assembly designed to provide mechanical and environmental protection for proximity probes mounted through machine cases. This specific configuration features the base 31000 housing assembly without an installed probe (Option A: 00), without a probe cable (Option B: 00), and without specialized standoff adapters, probe penetration, fittings, or mounting threads (all options 00/000). These housing assemblies are recommended for radially mounted transducers used in vibration or Keyphasor measurements. The 31000 series allows for external access to the proximity probe and its extension cable, enabling gap adjustments or probe replacements without the need to disassemble the machinery. Constructed from polyphenylene sulfide (PPS), this assembly offers high-strength, corrosion-resistant performance, with additional components manufactured from corrosion-resistant stainless steel. The design is fully compliant with the American Petroleum Institute (API) 670 Standard for externally mounted proximity probe housings.

Features

• PPS thermoplastic housing body for high-strength and corrosion resistance
• API 670 compliant design for externally mounted proximity probe housings
• Enables external access for gap adjustment and probe maintenance
• Designed for radial vibration and Keyphasor measurement applications
• Provides robust mechanical and environmental protection for the transducer system

Applications

• Power generation machinery
• Oil and gas production equipment
• Petrochemical processing plants
• Rotating machinery protection systems
• Radial vibration and Keyphasor measurement setups

Installation Guidelines

• Ensure the machine casing is affixed to the bearing to maintain an accurate relative vibration signal for radial measurements.
• Install the outer sleeve into the machine case as required for specific thread options.
• The housing cover should be secured with the provided captive screws after probe installation and gap adjustment.
• If hole plugs are used to seal unused ports, tighten the plug nuts to 0.5 N-m (5 in-lbs).
• Consult the 31000/32000 User Guide (124200) for detailed procedures on probe gap adjustment and cable routing.
