Bently Nevada 330881-16-10-105-06-02 PROXPAC XL Proximity Transducer

Description

330881-16-10-105-06-02 specifies this metric PROXPAC XL proximity transducer assembly, featuring a 3300 XL 8 mm probe without approvals (Option 16), a 100 mm standoff adapter (Option 10), and a 105 mm probe penetration length (Option 105).

This integrated proximity transducer is housed in a molded thermoplastic assembly made of glass and conductive fiber-reinforced Polyphenylene Sulfide (PPS), which provides IP66 and Type 4X protection against harsh industrial environments. By incorporating the 3300 XL Proximitor sensor directly within the housing cover, this unit functions as a self-contained eddy-current measurement system that eliminates the need for separate Proximitor housings or intermediate extension cables. Field wiring connects directly to terminal blocks inside the enclosure, streamlining installation on rotating machinery.

Features

• Option 16 integrates a 3300 XL 8 mm proximity probe with a 1-meter cable length directly inside the protective sleeve.
• Option 10 provides a 100 mm metric standoff adapter to adjust the probe's clearance from the target surface.
• Option 105 defines a 105 mm probe sleeve penetration length, ordered in 1 mm increments.
• Option 06 includes a fittings kit with one 3/4-14 NPT fitting, one 3/4-14 NPT to 1 1/2-14 NPT stainless steel reducer, and two plugs for conduit connections.
• Option 02 configures a 3/4-14 NPT outer mounting thread, which is required for installations utilizing the standoff adapter.
• Polyphenylene Sulfide (PPS) molded housing is strengthened with glass and conductive fibers to dissipate electrostatic charges and withstand severe environments.
• Enclosure rated for IP66 and Type 4X to resist hose-directed water and environmental contaminants.
• Internal terminal block allows direct field wiring to the vibration monitoring system, avoiding external extension cables.

Applications

• Shaft vibration and axial position measurement on rotating machinery.
• Non-contact proximity measurements in steam turbines, gas turbines, compressors, and pump systems.
• Severe environmental installations requiring Type 4X and IP66 chemical or water protection.
• Space-constrained installations where a separate external Proximitor sensor housing is not practical.

Installation Guidelines

To establish a proper environmental seal, verify that the housing cover and all conduit connection points are fully secure. Take precautions to prevent moisture from traveling through the conduit piping into the housing. Tighten the retaining nut to the recommended torque of 29.5 N-m (260 in-lb) and the probe sleeve locknut to 39.3 N-m (350 in-lb). Maintain the recommended gap setting of 1.27 mm (50 mils) between the probe tip and the target material during setup.
