Bently Nevada 21000-34-05-15-29-04-02 Proximity Probe Housing Assemblies

Description

The 21000-34-05-15-29-04-02 is a configured proximity probe housing assembly designed for use with the 3300 XL NSv proximity transducer system. This specific variant includes a 3300 XL NSv probe with a connector protector and selectable hazardous area approvals (Option 34). It features a 0.5 m (20 in) probe cable length (Option 05) and a 1.5 in (38 mm) standoff adapter (Option 15). The probe penetration is set to 2.9 in (Option 29), combined with a 3/4-14 NPT plug (Option 04) and 3/4-14 NPT mounting thread (Option 02).

The 21000 series aluminum housing provides protection for externally mounted proximity probes in industrial environments. It facilitates secure installation and maintains environmental integrity, ensuring consistent measurements for machinery vibration and position monitoring. The design is optimized for integration with 3300 XL systems, providing robust support and cable management. This assembly is standard-rated for various industrial applications and must be installed according to the appropriate probe system user guide to ensure proper performance.

Installation Guidelines

• Ensure the probe lead is longer than the sleeve to maintain proper system connectivity.
• For probe penetration lengths (C + D) greater than 300 mm (12 in), provide additional sleeve support to prevent resonance.
• Avoid exposing 3300 XL or 3300 NSv probes to temperatures below -34 degC (-30 degF) to prevent pressure seal failure.
• Use appropriate thread sealing techniques for NPT connections to maintain environmental ratings.
• Refer to the 3300 XL NSv Proximity Transducer System User Guide (document 147357) for specific electrical installation and gap requirements.

Compliance and Certifications

• RoHS Directive 2011/65/EU
• CSA certified for explosion-proof applications (CA versions only for North American end users)
