330881-16-04-138-03-02 combines the probe and Proximitor sensor in one PROXPAC XL assembly, eliminating the extension cable and separate Proximitor housing.
The complete catalog number fixes the 40 mm standoff, 138 mm penetration, M20 fitting kit, and 3/4-14 NPT mounting interface.
Use Baker Hughes datasheet 178554 Rev. E and the installation instructions to confirm the complete mechanical and monitoring-system interface before replacement.
330881-16-04-138-03-02 is a metric PROXPAC XL Proximity Transducer Assembly configured with a 3300 XL 8 mm probe without approvals. Its integrated housing contains the 3300 XL Proximitor sensor, so field wiring connects directly between the monitor and the assembly.
The complete suffix specifies a 40 mm standoff adapter, 138 mm probe penetration, one M20 fitting with two plugs, and a 3/4-14 NPT mounting thread. These values are configuration identifiers from Baker Hughes datasheet 178554 Rev. E.
Before replacing 330881-16-04-138-03-02, verify every suffix group, mounting interface, target geometry, probe-tip spacing, sealing, field wiring, grounding, monitor connection, and the absence of approvals for option 16.
