        Features:

        • Self-contained design with integrated Proximitor sensor in the housing cover eliminates extension cables and separate sensor enclosures.
        • 40 mm standoff adapter combined with 150 mm probe penetration provides exceptional reach for deep-well mounting through thick casings or insulation.
        • 3/4-14 NPT mounting thread with multiple hazardous area approvals allows direct installation in classified locations worldwide.
        The 330881-28-04-150-00-02 is engineered for installations where the measurement point sits deep inside the machine casing. Its 40 mm standoff adapter pushes the housing away from the casing surface, clearing insulation layers or providing tool access, while the 150 mm probe penetration delivers the sensing tip far into the machine. This combined reach—190 mm from the mounting surface—eliminates the need for stacked standoffs or custom mounting hardware. The 3/4-14 NPT thread matches standard ports, ensuring a secure, leak-tight seal in high-pressure applications.

        Unlike traditional systems that require a probe, extension cable, and separate Proximitor housing, the 330881-28-04-150-00-02 integrates the Proximitor sensor directly into the housing cover. Field wiring connects straight from monitors to the assembly, reducing component count, eliminating the extension cable, and cutting potential failure points by two connectors. For system integrators, this means smaller control cabinets and faster commissioning. For maintenance teams, it means fewer parts to track and fewer connections to troubleshoot.

        The 330881-28-04-150-00-02 comes with a 3300 XL 8 mm probe that carries multiple hazardous area approvals, making it suitable for deployment in classified locations across North America, Europe, and other international markets. The self-contained design further simplifies compliance by keeping all sensitive electronics within the certified housing. For facilities operating in explosive environments—refineries, chemical plants, offshore platforms—this assembly provides the reach, protection, and certifications needed for critical machinery monitoring without the complexity of multi-component systems.

        The 330881-28-04-150-00-02 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).

        • Small, high-speed machinery: such as small turbochargers, high-speed centrifugal pumps, or laboratory-grade rotary equipment.
        • Narrow space monitoring: when the radial space of the installation location is insufficient to accommodate a standard probe (e.g., inside a bearing housing).
        • Small target measurement: when the diameter of the rotating shaft is less than 13 mm (0.5 inches), standard probes cause severe lateral interference; this model can accurately focus on small targets.
        • Average Sensitivity: 7.87 V/mm (200 mV/mil) in standard configuration, twice the sensitivity of a standard 8 mm probe, enabling more sensitive detection of minute vibrations.
        • Sidewall Interference Resistance: Its design reduces lateral magnetic field divergence, resulting in significantly less signal distortion than standard probes when installed close to the metal housing (sidewall).
        • Physical Structure: Utilizes a 303 stainless steel housing and PPS sensor head, providing excellent resistance to chemical corrosion.
        • Reduce Downtime: Precise monitoring of small, critical equipment enables predictive maintenance, preventing sudden failures caused by bearing wear or rotor imbalance.
        • System Compatibility: When used with the 3300 XL NSv preamplifier, it can be directly connected to the 3500 monitoring system, achieving millisecond-level automatic protection interlocks.

        Description
        The 330881-28-04-150-00-02 combines a 3300 XL 8 mm probe with multiple approvals into a completely self-contained proximity transducer system. Its 40 mm standoff adapter and 150 mm probe penetration provide exceptional reach for deep-well mounting applications, while the integrated Proximitor sensor eliminates the need for an extension cable between the probe and its associated electronics. 

        With its 3/4-14 NPT mounting thread, the 330881-28-04-150-00-02 secures directly to the machine casing. The housing cover contains its own 3300 XL Proximitor sensor, making this assembly a complete system without requiring a separate Proximitor enclosure. 

        The 330881-28-04-150-00-02 retains the same advantages as traditional 31000/32000 housings for accessing and externally adjusting proximity probes. The 40 mm standoff adapter pushes the housing away from the casing, providing clearance for insulation layers or installation tools.

        This self-contained system solves the pain point of complex installations by integrating the Proximitor sensor directly into the housing, eliminating extension cables and separate sensor enclosures.
