More Information

Overview Manuals Wiring Response Environment Application

Features:

  • Self-contained system: the housing cover contains its own 3300 XL Proximitor sensor.
  • Catalog configuration: a 3300 XL 8 mm probe without approvals is paired with metric option groups.
  • Protected housing: the PPS enclosure is documented for Type 4X and IP66 environments.

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.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

Field Wiring

  • Supply: -17.5 to -26 Vdc without barriers at 12 mA maximum consumption.
  • Conductors: 0.2 to 1.5 mm² (16 to 24 AWG) field wiring is documented.
  • Cable run: shielded three-conductor triax cable is recommended, with up to 305 m between sensor and monitor.

Measurement Response

  • Scale factor: 7.87 V/mm (200 mV/mil), ±5% under the documented conditions.
  • Linearity: deviation from best fit straight line is less than ±0.025 mm for the standard 1 m system at 0 to 45 ℃.
  • Target: the documented minimum flat-target diameter is 15.2 mm.

Environmental Limits

  • Probe: documented operating temperature is -52 to +177 ℃.
  • Housing and sensor: documented operating temperature is -52 to +100 ℃.
  • Humidity: 100% condensing, non-submersible service is specified when connectors are protected.

Application

  • Radial vibration: apply the documented probe-tip separation and shaft-diameter guidance to limit cross-talk.
  • Axial position: verify target size, gap, and probe spacing before commissioning the measurement.
  • Integrated monitoring: connect field wiring directly between the monitor and the self-contained PROXPAC XL assembly.
Description

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.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can Bently Nevada 330881-16-04-138-03-02 be used where hazardous-area approval is required?
Not as this exact configuration. Option 16 identifies a 3300 XL 8 mm probe without approvals, so an application that requires hazardous-area approval must use an appropriately approved catalog configuration and follow the applicable installation drawing.
What should be checked if Bently Nevada 330881-16-04-138-03-02 does not produce the expected proximity signal?
Confirm the documented sensor supply, verify the probe gap and target material and size, inspect the protected connectors and shielded three-conductor field wiring, and check continuity to the monitor. Follow the Baker Hughes installation instructions before adjusting or replacing the assembly.
How does the integrated design of Bently Nevada 330881-16-04-138-03-02 affect field wiring?
The PROXPAC XL housing contains its own 3300 XL Proximitor sensor. This removes the extension cable and separate Proximitor housing, allowing field wiring to run directly between the monitor and the assembly.
What electrical and field-wiring limits apply to Bently Nevada 330881-16-04-138-03-02?
The sensor requires -17.5 to -26 Vdc without barriers at 12 mA maximum consumption. The datasheet permits 0.2 to 1.5 mm2 (16 to 24 AWG) field wiring and recommends shielded three-conductor triax cable.
Can a different 330881 suffix replace Bently Nevada 330881-16-04-138-03-02 directly?
Not without verification. A changed suffix can alter approvals, standoff length, penetration, fittings, or mounting thread, so all five option groups and the machine interface must match before replacement.
Which official document should be checked for Bently Nevada 330881-16-04-138-03-02?
Use the Baker Hughes PROXPAC XL Proximity Transducer Assembly Datasheet 178554 Rev. E. Its 330881 metric ordering table confirms every suffix in the complete catalog number.
What details should a buyer provide when requesting Bently Nevada 330881-16-04-138-03-02?
Provide the complete catalog number, nameplate details, required quantity, monitor connection, mounting interface, and confirmation of the 40 mm standoff, 138 mm penetration, M20 fitting kit, and 3/4-14 NPT thread.
