Bently Nevada 330881-16-08-095-06-02 PROXPAC XL Proximity Transducer

Description

330881-16-08-095-06-02: PROXPAC XL Proximity Transducer, Metric configuration with a 3300 XL 8 mm probe without approvals, an 80 mm standoff adapter, a 95 mm probe penetration, a specialized 3/4-14 NPT fitting with SST reducer, and a 3/4-14 NPT outer sleeve mounting thread.

This integrated assembly brings the 3300 XL 8 mm probe and Proximitor sensor into a unified, self-contained unit, eliminating the need for an external extension cable and reducing overall field wiring complexity. Unlike variants that omit probe sensors or feature North American/European multi-approvals, this specific transducer includes a 3300 XL 8 mm probe (Option 16) with standard non-approved ratings, combined with a robust Polyphenylene Sulfide (PPS) thermoplastic housing for Type 4X and IP66 severe environment protection.

Features

• Integrated 3300 XL 8 mm proximity probe (Option 16) with standard non-approved rating.
• Pre-installed 80 mm metric standoff adapter (Option 08) for specialized mounting offsets.
• Sleeve penetration length of 95 mm (Option 095) for deep machine casing access.
• Premium fittings kit featuring one 3/4-14 NPT fitting, one 3/4-14 NPT to 1/2-14 NPT SST reducer, and two plugs (Option 06).
• Outer sleeve mounting with 3/4-14 NPT threads (Option 02) to secure the standoff adapter assembly.
• Advanced PPS thermoplastic housing incorporating glass and conductive fibers to dissipate electrostatic charges.

Applications

• Radial vibration and axial position measurements on rotating machinery.
• Fluid-film bearing monitoring in severe industrial environments.
• Heavy-duty machinery protection where separate Proximitor sensor cabinets are impractical.

Installation Guidelines

• Environmental Sealing: Ensure all field wiring conduit entries are properly sealed. While the PPS housing is rated for IP66 and Type 4X, moisture must be prevented from migrating through conduit paths.
• Standoff Alignment: Secure the 3/4-14 NPT outer sleeve threads (Option 02) tightly to lock the 80 mm standoff adapter in place before fine-tuning probe position.
• Probe Air Gap Adjustment: Adjust the probe sleeve gap with the machine shaft static. Standard linear range center is ideally located at a voltage reading corresponding to the target calibration.
• Torque Limits: Never exceed 29.5 N-m (260 in-lb) on the housing retaining nut or 39.3 N-m (350 in-lb) on the probe sleeve locknut to prevent damage to the composite housing.
