Bently Nevada 330881-16-00-395-06-02 PROXPAC XL Proximity Transducer

Description

330881-16-00-395-06-02 specifies a metric Bently Nevada PROXPAC XL integrated proximity transducer configuration, pairing a 3300 XL 8 mm proximity probe (Option 16) with a 395 mm probe penetration depth (Option 395). This self-contained, integrated assembly incorporates its own 3300 XL Proximitor sensor inside the housing lid, eliminating the need for an intermediate extension cable or a separate Proximitor enclosure. Field wiring connects directly between the monitors and the terminal strip inside the housing, reducing installation complexity and wiring interfaces.

This configuration operates without an external standoff adapter (Option 00) and features a 3/4-14 NPT mounting thread (Option 02). It is supplied with a fittings kit (Option 06) containing one 3/4-14 NPT fitting, one 3/4-14 NPT to 1/2-14 NPT stainless steel reducer, and two plugs. The housing is constructed of glass-reinforced, conductive-fiber-filled polyphenylene sulfide (PPS) thermoplastic, which resists chemical exposure, provides IP66 and Type 4X sealing, and dissipates electrostatic charges. Because this unit is ordered with Option 16, it is supplied without hazardous area agency approvals.

Features

• Option 16 integrates a 3300 XL 8 mm proximity probe without hazardous area approvals.
• Option 00 configures the transducer assembly without an external standoff adapter.
• Option 395 provides a deep 395 mm probe penetration length for machinery cases.
• Option 06 includes a metric/NPT fittings kit with one 3/4-14 NPT fitting, one 3/4-14 NPT to 1/2-14 NPT stainless steel reducer, and two plugs.
• Option 02 provides a 3/4-14 NPT mounting thread.
• Self-contained design locates the Proximitor sensor in the housing lid, eliminating remote sensor enclosures and separate extension cables.
• Polyphenylene sulfide (PPS) housing material offers chemical resistance and resists electrostatic charge accumulation.

Applications

• Shaft radial vibration and axial position measurement on industrial rotating machinery.
• Direct-mount external casing probe installations where separate Proximitor housings are impractical.
• Severe-environment machinery monitoring requiring IP66 and Type 4X environmental protection.

Ordering Information

The 330881-16-00-395-06-02 represents a specific orderable configuration of the metric PROXPAC XL Proximity Transducer Assembly. The table below decodes each option segment of this SKU:

Technical Specifications

Installation Guidelines

• Ensure the target shaft or surface meets the minimum target diameter of 15.2 mm (0.6 in) to achieve full linear calibration.
• To prevent measurement cross-talk, maintain a minimum separation of 40 mm (1.6 in) for axial position measurements and 38 mm (1.5 in) for radial vibration measurements.
• Do not expose the probe to temperatures below -34 degC (-29 degF) during operation to avoid premature failure of the pressure seal.
• Torque the probe sleeve locknut to 39.3 N-m (350 in-lb) and the housing retaining nut to 29.5 N-m (260 in-lb) during final physical mounting.
• Seal all conduit entries and utilize the supplied fittings (Option 06) to prevent moisture or condensation from traveling through the conduit into the housing cavity.

Compliance and Certifications

• Complies with European CE mark.
• Housing IP66 rating verified by BASEEFA report number T07/0709.
• Note: Because this specific assembly is configured with Option 16, it does not come with hazardous area agency approvals.
