Information

Overview Manuals Principle

Features:

  • PROXPAC XL Proximity Transducer Assembly
  • Similar to our 31000/32000 Proximity Probe Housing Assemblies
  • Made of Polyphenylene Sulfide (PPS), which is an advanced, molded thermoplastic
The assembly offers the same advantages and features as the 31000 and 32000 housings for accessing and externally adjusting proximity probes. However, the housing cover of the PROXPAC XL Assembly also contains its own 3300 XL Proximitor sensor.

This design makes the PROXPAC XL Assembly a completely self-contained proximity probe system, and eliminates the need for an extension cable between the probe and its associated Proximitor sensor. It also eliminates the need for a separate Proximitor housing, as the field wiring connects directly between the monitors and PROXPAC XL Assemblies.

The 330881-16-04-138-03-02 Bently Nevada PROXPAC XL Proximity Transducer Assembly may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Bently Nevada 330881-16-04-138-03-02 PROXPAC XL Proximity Transducer Assembly Manuals(Datasheets), Link 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.
The PROXPAC XL housing is made of polyphenylene sulfide (PPS), an advanced molding thermoplastic material. This material replaces the steel and aluminum used in previous housings in the Bently Nevada product line. Furthermore, glass fiber and conductive fibers are added to the PPS to enhance housing strength and more effectively dissipate static charge. The PROXPAC XL housing meets Type 4X and IP66 protection ratings, providing extra protection in harsh environments.

  • What is the system-level metrological architecture of 330881-16-04-138-03-02, and how does 330881-16-04-138-03-02 integrate probe, cable, and signal conditioning into a unified calibrated assembly?
    The 330881-16-04-138-03-02 is a factory-matched PROXPAC XL proximity transducer assembly engineered as a fully integrated measurement chain. It combines the eddy-current probe, extension cable, and Proximitor® electronics into a pre-characterized system, ensuring that 330881-16-04-138-03-02 delivers defined sensitivity, linearity, and impedance matching without requiring field-level electrical matching.
  • How does 330881-16-04-138-03-02 implement eddy-current transduction physics to achieve non-contact displacement measurement?
    The 330881-16-04-138-03-02 operates by generating a high-frequency electromagnetic field through the probe coil. When the probe is positioned near a conductive rotor surface, induced eddy currents alter the coil impedance proportionally to the probe-to-target gap. The 330881-16-04-138-03-02 converts this impedance modulation into a stable voltage output representing precise shaft displacement.
  • Why is factory calibration critical for ensuring measurement traceability in 330881-16-04-138-03-02?
    The 330881-16-04-138-03-02 is delivered as a pre-calibrated and electrically matched assembly, meaning that its probe sensitivity, cable characteristics, and Proximitor® gain are aligned at manufacturing. This system-level calibration ensures that 330881-16-04-138-03-02 maintains consistent scale factor accuracy and eliminates field uncertainties caused by component substitution.
  • What defines the linear operating envelope of 330881-16-04-138-03-02, and how is measurement fidelity preserved within that range?
    The 330881-16-04-138-03-02 operates within a defined linear displacement region where the output voltage maintains proportionality to gap variation. Proper gap adjustment ensures that 330881-16-04-138-03-02 functions in the midpoint of its calibrated range, minimizing nonlinear distortion and maximizing dynamic measurement resolution.
  • How does 330881-16-04-138-03-02 support radial vibration and axial position monitoring in rotating machinery?
    The 330881-16-04-138-03-02 is optimized for shaft-relative measurement applications such as radial vibration, eccentricity monitoring, and thrust position tracking. Because it measures relative displacement between the probe and conductive surface, 330881-16-04-138-03-02 is ideally suited for fluid-film bearing systems and high-speed turbomachinery diagnostics.
  • What electromagnetic compatibility mechanisms protect 330881-16-04-138-03-02 from industrial noise interference?
    The 330881-16-04-138-03-02 incorporates shielded cabling, grounded housings, and internal filtering circuitry to suppress electromagnetic interference. These EMC design features ensure that 330881-16-04-138-03-02 maintains signal integrity in electrically noisy environments containing high-power drives and switching equipment.
