Features:

  • Integrated 3300 XL Proximitor sensor in housing cover eliminates the need for separate extension cables and external Proximitor enclosures.
  • Self-contained design with 2.0 in standoff adapter and 3.8 in probe penetration allows external probe adjustment without machine disassembly.
  • Probe sold separately configuration enables users to select the optimal probe for their specific application requirements.
The 330880-00-20-038-00-02 represents a significant departure from traditional probe housing designs by integrating the Proximitor sensor directly into the housing cover. In conventional systems, the Proximitor sensor is mounted separately in a control cabinet or junction box, requiring an extension cable to connect it to the probe.

Despite its integrated electronics, the 330880-00-20-038-00-02 retains the external adjustment capabilities that make probe housings valuable in the first place. The housing cover provides access to the probe for gap adjustment and replacement without requiring machine disassembly—a critical feature for maintaining critical rotating equipment.

The 330880-00-20-038-00-02 is configured without a pre-installed probe, giving system designers and maintenance engineers complete freedom to select the optimal 3300 XL 8 mm probe for their specific application. This flexibility is particularly valuable when probes with specialized approvals, extended temperature ratings, or specific case lengths are required.

The 330880-00-20-038-00-02 Bently Nevada PROXPAC XL Proximity Transducer, English may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Condition New Original ready stock
  • Product Family 330880-16-20-038-00-02,330880-28-20-038-00-02,330880-00-20-038-03-02

  • Small Rotary Machinery: Specifically designed for shafts with diameters less than 51 mm (2 in), such as small centrifugal compressors, refrigeration units, high-speed pumps, and centrifuges.
  • Space-Confined Locations: The probe tip design reduces the "side-view effect," making it suitable for installation in reverse-bored locations or confined spaces near metal walls.
  • Radial and Axial Monitoring: Measures radial vibration of high-speed shafts and axial (thrust) displacement of small planar targets.
  • 3.8-meter total length: This model comes with a longer cable (038). When connecting to the 3300 XL NSv Proximitor preamplifier, ensure that the total length of the probe and extension cable meets the preamplifier's calibration requirements (typically, the total system length is 5 or 7 meters).
  • Signal output: The preamplifier converts the gap change sensed by the probe into a linear voltage signal.
  • Sensitivity: Standard proportional factor (ISF) is 7.87 V/mm (200 mV/mil).
  • Certification Level: 02 indicates "No institutional certification required." This applies to installation environments in non-hazardous areas (non-explosion-proof areas) or where external safety barriers are installed.
  • Material: The probe head is made of PPS (polyphenylene sulfide) engineering plastic, offering excellent chemical corrosion resistance (superior to the older RAM series).
  • Sealing: The housing design meets industrial sealing standards, preventing lubricating oil from leaking from the bearing housing to the cable ends.
Description
The 330880-00-20-038-00-02 is a self-contained proximity probe system that integrates the Proximitor sensor directly into the housing cover, eliminating the need for separate extension cables and external Proximitor enclosures. Its 2.0-inch standoff adapter and 3.8-inch probe penetration provide precise positioning flexibility for a wide range of machinery configurations. 

With no pre-installed probe, the 330880-00-20-038-00-02 offers maximum flexibility for system integrators and OEMs who need to pair the housing with probes that have specific approvals or configurations. The integrated Proximitor sensor means field wiring connects directly between the monitors and the assembly, significantly reducing installation complexity and component count. 

The 330880-00-20-038-00-02 is constructed with materials suitable for demanding industrial environments. The assembly includes two plugs and two washers for installation flexibility, with no additional fittings required for standard installations. 

This PROXPAC XL assembly solves the pain point of complex installations by eliminating extension cables and separate Proximitor housings while maintaining the external adjustment capabilities of traditional probe housings.
