Information

Overview Manuals Principle Key Applications

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 330881-28-04-105-00-02 Bently Nevada PROXPAC 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 330881-28-04-105-00-02 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 previously used in Bently Nevada's 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.
  • Harsh Environments: Its housing is made of polyphenylene sulfide (PPS), a thermoplastic material reinforced with glass fiber and conductive fibers. This provides excellent corrosion resistance, moisture resistance, and chemical resistance, achieving an IP66 and 4X protection rating.
  • Predictive Maintenance: Used in high-speed rotating equipment such as centrifugal compressors, turbines, and large pumps to detect early signs of bearing wear, shaft imbalance, or misalignment.
  • Simplified Installation: By integrating the 3300 XL 8 mm probe and Proximitor sensor into a single factory-matched unit, separate extension cables and Proximitor housings are eliminated.
PRODUCT & ORDER FAQS

Questions buyers ask about 330881-28-04-105-00-02

  • What are the main metrological functions of the 330881-28-04-105-00-02 probe in an eddy current displacement measurement system?

    The 330881-28-04-105-00-02 is a precision proximity probe designed to convert sub-millimeter-level shaft displacement changes into proportional electrical signals, thereby enabling high-resolution vibration and position monitoring of rotating machinery.
  • How does the 330881-28-04-105-00-02 achieve a linear conversion between physical displacement and electrical signal output?

    The 330881-28-04-105-00-02 employs a calibrated coil geometry and a controllable high-frequency electromagnetic excitation field to ensure a predictable linear response within its specified measurement range.
  • Why is the 330881-28-04-105-00-02 optimized for high-speed turbomachinery environments?

    The 330881-28-04-105-00-02 employs a robust and durable mechanical structure, thermally stable materials, and electromagnetic interference-resistant shielding design to ensure operational integrity in environments with high vibration, high temperature, and electrical noise.
  • How does the 330881-28-04-105-00-02 facilitate rotor dynamics analysis and diagnostic modeling?

    The 330881-28-04-105-00-02 provides continuous shaft displacement data, thereby supporting advanced analysis techniques such as trajectory plotting, shaft centerline tracking, phase analysis, and transient event characterization.
  • Why is installation accuracy critical to the performance of the 330881-28-04-105-00-02?

    The 330881-28-04-105-00-02 requires precise air gap calibration, rigid mechanical mounting, and controlled cabling to ensure linear response characteristics and minimize measurement noise.
