Bently Nevada 31000-00-00-00-070-03-02 English Proximity Probe Housing Assembly

Description

The 31000-00-00-00-070-03-02 is a specialized English Proximity Probe Housing Assembly designed for mounting eddy-current proximity probes through machinery cases. This configuration includes the PPS (polyphenylene sulfide) housing with a 70 mm probe penetration depth (Option 070), two plugs, one M20 fitting, one cable seal grip (Option 03), and a 3/4-14 NPT mounting thread (Option 02). This housing assembly provides essential mechanical and environmental protection for proximity probes and their associated extension cables. It allows for external access, facilitating gap adjustments or probe replacements without requiring the disassembly of the machine. The assembly is fully compliant with the American Petroleum Institute (API) 670 Standard for externally mounted proximity probe housings and is suitable for radial vibration or Keyphasor measurements in industrial environments.

Features

• Housing Material: High-strength, corrosion-resistant polyphenylene sulfide (PPS) and stainless steel components.
• Probe Penetration (Option 070): Configured for 70 mm penetration depth.
• Mounting Thread (Option 02): 3/4-14 NPT mounting thread.
• Fittings (Option 03): Includes two plugs, one M20 fitting, and one cable seal grip for armored probe cable support.
• Access: Facilitates external gap adjustment and transducer maintenance without machinery disassembly.
• API 670 Compliance: Fully compliant with API 670 standards for externally mounted proximity probe housings.

Applications

• Radially mounted transducers for machinery vibration monitoring.
• Keyphasor measurement applications.
• Heavy industry rotating machinery protection (power generation, oil and gas, petrochemical, water, mining).
• Installations requiring environmental protection for proximity probe connections.

Installation Guidelines

• Install the outer sleeve into the machine case before mounting the housing.
• The housing assembly must be installed in conjunction with an approved transducer system.
• When using hole plugs, tighten hole plug nuts to 0.5 N-m (5 in-lbs) to ensure a proper seal.
• Ensure the machine casing is affixed to the bearing when using the housing for radial vibration measurement.
• Consult the 31000 and 32000 User Guide (Document 124200) for detailed wiring and assembly torque specifications.

Compliance and Certifications

• API 670 Standard (Externally mounted proximity probe housings)
• Hazardous area applications (when installed with appropriate I.S. barriers and transducer systems)
