Bently Nevada 31000-30-05-40-014-03-02 English Proximity Probe Housing Assemblies

Description

The 31000-30-05-40-014-03-02 is a specialized 31000 series proximity probe housing assembly, configured for the integration of a 3300 XL NSv proximity probe with a connector protector (Option 30). This assembly features a 0.5 m probe cable length (Option 05), a 40 mm standoff adapter length (Option 40), and specific probe penetration settings (Option 014). It includes two plugs, one M20 fitting, and one cable seal grip for armored probe cables (Option 03), mounted via a 3/4-14 NPT thread (Option 02).

Engineered for use in rotating machinery, the 31000 series housing allows for external access to the proximity probe and its extension cable. This design facilitates efficient gap adjustment and probe replacement without requiring the disassembly of the machine case. Constructed from high-strength, corrosion-resistant polyphenylene sulfide (PPS) with stainless steel components, this assembly provides mechanical and environmental protection compliant with API 670 standards.

Features

• 3300 XL NSv probe configuration with connector protector (Option 30)
• 0.5 m probe cable length (Option 05)
• 40 mm standoff adapter length (Option 40)
• Integrated M20 fitting with cable seal grip for armored cable protection (Option 03)
• 3/4-14 NPT mounting thread (Option 02)
• Polyphenylene sulfide (PPS) housing construction for superior corrosion resistance
• Compliant with API 670 standards for externally mounted proximity probe housings
• External access design for gap adjustment and probe maintenance

Applications

The 31000 series housing is used for mounting proximity probes through machine cases in heavy industrial environments, including:

• Power generation facilities
• Oil and gas petrochemical processing
• Radial vibration and axial position measurement
• Critical rotating machinery protection
• Intrinsically safe hazardous area applications (when used with approved transducer systems and I.S. barriers)

Technical Specifications

Installation Guidelines

Install the outer sleeve directly into the machine case before fitting the housing. When measuring radial vibration, ensure the machine casing is affixed to the bearing to maintain an accurate relative vibration signal. Tighten hole plug nuts to 0.5 N-m (5 in-lbs) if unused holes are present. For probe penetration lengths between 25 and 50 mm, counter-boring the machine case may be necessary to minimize side-view or rear-view effects.

Compliance and Certifications

Compliant with API 670 Standard. Suitable for use in intrinsically safe hazardous area applications when installed with compatible transducer systems and appropriate I.S. barriers.
