Description

Option 28 (Multiple Approvals probe) and Option 04 (40 mm standoff) specify this PROXPAC XL metric configuration - 330881-28-04-115-06-02, an integrated PROXPAC XL Proximity Transducer.

This integrated system combines an 8 mm proximity probe and a 3300 XL Proximitor sensor directly into a single molded Polyphenylene Sulfide (PPS) housing. This eliminates the need for external extension cables and separate Proximitor housings, with field wiring connecting directly from the monitor to the transducer assembly. It is used for non-contact displacement measurements, including shaft vibration and axial position, on rotating machinery.

Features

Option 28 provides an integrated 3300 XL 8 mm proximity probe certified with Multiple Approvals.
Option 04 specifies a 40 mm standoff adapter length (B Dimension).
Option 115 provides a probe penetration depth of 115 mm (C Dimension).
Option 06 supplies a fitting kit with one 3/4-14 NPT fitting, one 3/4-14 NPT to 1 1/2-14 NPT stainless steel (SST) reducer, and two plugs.
Option 02 provides a 3/4-14 NPT mounting thread, matching requirements for standoff installations.
Housing molded from glass-reinforced, UV-resistant Polyphenylene Sulfide (PPS) with conductive fibers to dissipate electrostatic charges.
IP66 environmental protection rating certified by BASEEFA to withstand severe industrial conditions.
Integrated design houses both probe and Proximitor sensor, eliminating separate sensor housings and intermediate extension cables.

Applications

Shaft vibration monitoring on high-speed industrial turbomachinery.
Axial rotor position measurement on steam turbines, gas turbines, and compressors.
Rotating machinery protection systems where simplified installation and direct field wiring are required.
Hardline conduit installations or high-moisture environments needing IP66/Type 4X enclosure protection.

Installation Guidelines

Follow Bently Nevada drawing 141092 for intrinsically safe installations and drawing 140979 for non-incendive/non-sparking installations.
Mount housing using the 3/4-14 NPT thread (Option 02) through the machine case, ensuring proper O-ring sealing to maintain the IP66/Type 4X rating.
Secure the standoff adapter and sleeve according to recommended torque values: retaining nut to 29.5 N-m and probe sleeve locknut to 39.3 N-m.
Protect cabling within a suitable conduit system. Option 06 provides the required SST reducer and fittings for robust connection to 1-1/2 NPT conduit or piping.
