        Features:

        • Integrated Proximitor Sensor Within Probe Housing Assembly
        • Eliminates Extension Cable Requirements Through Self-Contained Design
        • Replaces Traditional Steel/Aluminum Construction with Advanced Thermoplastic Material
        The 330881-28-04-090-03-02 PROXPAC XL Proximity Transducer operates as a completely self-contained proximity probe system, providing reliable vibration monitoring and machinery protection capabilities in industrial environments. It continuously performs proximity sensing functions through its integrated 3300 XL 8 mm probe with multiple approvals, distributing accurate displacement measurements directly to monitoring systems without the need for intermediate extension cables. Seamless integration is standard with the 330881-28-04-090-03-02, however its unique housing design also incorporates the Proximitor sensor internally, eliminating the requirement for separate sensor housings and enabling direct field wiring connections between monitors and the 330881-28-04-090-03-02 assemblies. The 330881-28-04-090-03-02 has made improvements in several areas over previous 31000/32000 housing designs in addition to incorporating advanced PPS thermoplastic construction within the proximity transducer assembly.

        The 330881-28-04-090-03-02 provides essential proximity sensing functions for accessing and externally adjusting probes, and is a critical component of the monitoring path, directly affecting the proper, normal operation of machinery protection systems. One 330881-28-04-090-03-02 assembly is required per monitoring point depending on the specific measurement location. The 330881-28-04-090-03-02 occupies a compact installation footprint with 90 mm probe penetration depth and is configurable with 40 mm standoff adapter options for flexible mounting arrangements.

        For severe environment applications, the 330881-28-04-090-03-02 PROXPAC XL Proximity Transducer incorporates specialized material properties within its housing design. In addition to standard proximity sensing operation, the environmental configuration also performs electrostatic charge dissipation. The 330881-28-04-090-03-02 PPS housing executes protection using glass and conductive fibers specified in the thermoplastic material options. Using this method, the housing system continually withstands exposure to dust and water ingress. If the installation environment presents challenging conditions (outside standard industrial tolerance levels), the 330881-28-04-090-03-02 will maintain its Type 4X and IP66 ratings and provide extra protection in severe environments.

        The 330881-28-04-090-03-02 Bently Nevada PROXPAC XL Proximity Transducer may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Description
        The 330881-28-04-090-03-02 PROXPAC XL Proximity Transducer is a completely self-contained proximity probe system designed for industrial vibration monitoring and machinery protection applications. This 330881-28-04-090-03-02 assembly eliminates the need for an extension cable between the probe and its associated Proximitor sensor, as well as the need for a separate Proximitor housing, making it an ideal solution for installations where simplified wiring and reduced component count are critical requirements.

        The 330881-28-04-090-03-02 features a 3300 XL 8 mm probe with multiple approvals, ensuring compliance with various international standards and certifications for global deployment. The 330881-28-04-090-03-02 is equipped with a 40 mm standoff adapter option and provides a probe penetration depth of 90 mm, allowing for flexible installation configurations in different machinery setups. For sealing and connectivity, the 330881-28-04-090-03-02 includes one M20 fitting and two plugs, with a 3/4-14 NPT mounting thread required when ordering the standoff adapter option.

        The design of the 330881-28-04-090-03-02 PROXPAC XL Proximity Transducer Assembly is similar to Bently Nevada's 31000/32000 Proximity Probe Housing Assemblies, offering the same advantages and features for accessing and externally adjusting proximity probes. However, the housing cover of the 330881-28-04-090-03-02 also contains its own 3300 XL Proximitor sensor, enabling field wiring to connect directly between the monitors and the 330881-28-04-090-03-02 assemblies without intermediate components.

        The 330881-28-04-090-03-02 housing is constructed from Polyphenylene Sulfide (PPS), an advanced molded thermoplastic material that replaces the steel and aluminum used in previous Bently Nevada housing designs. This 330881-28-04-090-03-02 housing incorporates glass and conductive fibers within the PPS material to strengthen the structure and more effectively dissipate electrostatic charges. The 330881-28-04-090-03-02 is rated for Type 4X and IP66 environments, providing enhanced protection in severe industrial conditions where exposure to dust, water, and corrosive elements is a concern.
