        Features:

        • Interface Between the 330881‑28‑04‑145‑03‑02 Proxpac XL Proximity Transducer and 3300 XL System Modules
        • Combines Capability of Shaft Displacement and Vibration Sensing with EMI‑Resistant Signal Transmission
        • Operates in Conjunction with 3300 XL 8 mm Proximity Probes and Standard 3300 XL Monitor Modules
        The 330881‑28‑04‑145‑03‑02 operates as a Proxpac XL Proximity Transducer assembly within the 3300 XL system, providing precise non-contact measurement of shaft displacement and vibration to all connected monitor modules. It continuously converts the probe signal into a standardized output and transmits it through interconnect cables to support reliable monitoring of critical rotating machinery. Seamless signal integrity is maintained under typical industrial operating conditions, while EMI‑resistant design ensures consistent performance in electrically noisy environments. The 330881‑28‑04‑145‑03‑02 incorporates improvements in mounting, environmental sealing, and probe configuration compared to earlier transducer assemblies, enabling reliable operation in harsh industrial applications.

        The 330881‑28‑04‑145‑03‑02 provides essential signal conditioning and measurement functions for the 3300 XL system, and is a critical component of the monitoring path, directly affecting accurate vibration and shaft displacement readings. One or more 330881‑28‑04‑145‑03‑02 transducer assemblies may be installed per monitored axis depending on the desired measurement configuration. The 330881‑28‑04‑145‑03‑02 mounts in standard sensor locations and interfaces seamlessly with 3300 XL monitor modules for reliable system operation..

        For critical monitoring applications requiring dual sensor coverage, the 330881‑28‑04‑145‑03‑02 can be deployed alongside a second transducer per monitored axis to ensure redundant measurement reliability. In addition to standard single‑sensor operation, the redundant configuration performs automatic signal validation and failover. The dual‑sensor setup continuously compares outputs from both transducers using the 3300 XL system’s internal diagnostic circuitry. If the system detects that the primary transducer signal falls outside configured thresholds, it automatically switches to the secondary transducer as the active measurement source and logs an event in the System Event List.

        The 330881-28-04-145-03-02 Bently Nevada Proxpac XL Proximity Transducer Assembly may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Description
        Its PPS housing and Type 4X/IP66 ingress protection ensure robust performance in demanding industrial environments. The transducer supports field wiring up to 305 meters (1,000 ft), providing flexible installation options for long-distance monitoring of rotating equipment.

        Bently Nevada 330881‑28‑04‑145‑03‑02 PROXPAC XL Proximity Transducer Assembly is a self‑contained industrial‑grade proximity transducer designed for vibration and shaft displacement monitoring in critical rotating machinery. 

        The unit incorporates a 3300 XL 8 mm proximity probe with multiple industry approvals into a rugged polyphenylene sulfide (PPS) housing with robust environmental protection (Type 4X/IP66), making it suitable for harsh industrial environments. This assembly eliminates the need for separate probe housings or external Proximitor modules by integrating the sensor and field wiring termination into a single compact unit.

        The transducer features a 40 mm standoff adapter and 145 mm probe penetration length, with mounting via a 3/4‑14 NPT thread and a fittings kit that includes one M20 fitting and two plugs for convenient installation. It accepts field wiring from the monitor interface and delivers standard proximity signals compatible with 3300 XL monitoring systems. Powered from a nominal −24 Vdc supply with low current consumption, the assembly supports long field wiring runs and reliable signal transmission for condition monitoring of turbines, compressors, motors, and other rotating equipment.
