PROXPAC XL Proximity Transducer Assembly

330880-16-00-021-03-02

Spare Part Number

PN330880-16-00-021-03-02

Product Information:

The 330880-16-00-021-03-02 is the PROXPAC XL integrated intelligent eddy current probe protective enclosure assembly manufactured by Bently Nevada. This highly integrated mechanical protection hardware features a revolutionary design that directly integrates the traditional external adjustment protective enclosure and the 3300 XL Proximitor Sensor within the enclosure cover.

It achieves a completely self-contained closed loop of "probe + preamplifier + protective enclosure," completely eliminating the easily damaged extension cable between the field probe and the preamplifier. It is widely deployed in shaft vibration, displacement, and speed measurement loops of critical rotating machinery such as steam turbines, centrifugal compressors, and high-pressure pumps.

Because the preamplifier is securely encased internally, the shielded cables in the control room can be directly connected to the high-vibration-resistant terminal blocks within the enclosure, significantly reducing high-frequency noise attenuation over long distances. This ensures continuous output of high-precision, zero-latency asset health status data to the Bently 3500 monitoring cabinet at the back end.

Information

Overview Manuals Basic Info Model Information Guide Certifications & Standards

Features:

  • PROXPAC XL Proximity Transducer
  • 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 330880-16-00-021-03-02 Bently Nevada PROXPAC XL Proximity Transducer may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

PRODUCT & ORDER FAQS

Questions buyers ask about 330880-16-00-021-03-02

  • What are the main engineering applications of the 330880-16-00-021-03-02 probe in high-performance rotating machinery monitoring systems?

    The 330880-16-00-021-03-02 is an advanced eddy current proximity probe assembly designed for precise, non-contact measurement of shaft vibration, radial displacement, axial position, and rotor dynamic characteristics. It is designed for integration into machinery protection and predictive maintenance systems where accurate displacement monitoring and high reliability are critical.
  • How does the 330880-16-00-021-03-02 utilize eddy current technology to provide accurate shaft displacement sensing?

    The 330880-16-00-021-03-02 employs the electromagnetic eddy current sensing principle. A high-frequency electromagnetic field is generated at the probe tip; changes in the distance between the probe and the conductive target surface alter the induced eddy current response. This device generates a proportional output signal with excellent measurement linearity, repeatability, sensitivity, and dynamic response characteristics.
  • What are the probe configuration and mechanical characteristics of proximity sensor assembly 330880-16-00-021-03-02?

    330880-16-00-021-03-02 uses a 16 mm probe configuration; the "16" in the model number indicates this configuration. This compact mechanical design provides installation flexibility, high structural integrity, and reliable sensing performance in space-constrained rotating machinery applications.
  • What are the cable length specifications for proximity probe assembly 330880-16-00-021-03-02?

    330880-16-00-021-03-02 uses a 0.21 m (approximately 8.3 inches) integrated cable; the "021" in the configuration number indicates this cable length. This short, integrated cable configuration is optimized for installation environments requiring compact wiring and direct connection to compatible extension cable assemblies and proximity drive electronics.
  • What calibration method is used to achieve high measurement accuracy for the 330880-16-00-021-03-02?

    The 330880-16-00-021-03-02 uses eddy current proximity measurement standards and is calibrated using a controlled reference target material (typically AISI 4140 steel) to ensure accurate sensitivity characteristics, predictable linear response, and compatibility with associated proximity signal conditioning electronics.
