Bently Nevada 31000-30-05-40-14-03-02 English Proximity Probe Housing Assembly

Description

The 31000-30-05-40-14-03-02 is a Bently Nevada English Proximity Probe Housing Assembly designed to house a 3300 XL NSv proximity probe. This configuration includes a 0.5 meter cable (Option 05), a 40 mm standoff adapter (Option 40), and a 14 mm probe penetration depth (Option 14). The assembly is engineered to provide secure mounting for radial vibration or Keyphasor measurements while allowing for probe gap adjustment and replacement without machine disassembly.

This housing is constructed from high-strength, corrosion-resistant polyphenylene sulfide (PPS) and stainless steel components, adhering to API 670 standards for externally mounted proximity probe housings. It features a connector protector for the 3300 XL NSv probe to ensure signal integrity. The assembly is configured with two housing plugs, one M20 fitting (Option 03), and a 3/4-14 NPT mounting thread (Option 02).

Features

• 3300 XL NSv proximity probe with integrated connector protector (Option 30)
• 0.5 m probe cable length (Option 05)
• 40 mm standoff adapter length for extended mounting clearance (Option 40)
• 14 mm probe penetration depth (Option 14)
• Fittings configuration: One M20 conduit fitting and two housing plugs (Option 03)
• 3/4-14 NPT machine case mounting thread (Option 02)
• Polyphenylene sulfide (PPS) housing material for chemical and corrosion resistance
• Compliant with API 670 standards

Applications

• Radial vibration monitoring on rotating machinery
• Keyphasor measurement and shaft position monitoring
• Hazardous area applications (when installed with appropriate I.S. barriers and transducer systems)
• Environments requiring external access to probes for gap adjustment

Installation Guidelines

Ensure the machine casing is affixed to the bearing for accurate relative vibration signals. Install the outer sleeve into the machine case before inserting the probe sleeve to adjust the gap. When utilizing the standoff adapter, ensure proper thread engagement. The housing should be secured with the provided retainer and retaining nut. If hole plugs are used, tighten to 0.5 N-m (5 in-lbs) to maintain environmental sealing.

Compliance and Certifications

Compliant with API 670 Standard for externally mounted proximity probe housings. Suitable for hazardous area use when installed as part of an approved intrinsically safe transducer system.
