Features:
- Integrates probe and Proximitor sensor in one PPS housing.
- Durable thermoplastic with glass fibers for severe environment protection.
- Ex ia IIC and IECEx certified for Zone 0/Division 1 explosive atmospheres.
The 330881-16-04-132-03-02 is a PROXPAC XL Proximity Transducer Assembly that integrates the 3300 XL Proximitor sensor directly into the housing cover. This self-contained design eliminates the need for an extension cable between the probe and its associated Proximitor sensor, reducing potential connection points and improving system reliability. The 330881-16-04-132-03-02 also eliminates the need for a separate Proximitor housing, as field wiring connects directly between monitors and the PROXPAC XL assemblies. This simplifies installation and reduces maintenance complexity.
The 330881-16-04-132-03-02 features a housing made of Polyphenylene Sulfide (PPS), an advanced molded thermoplastic reinforced with glass and conductive fibers for enhanced strength and electrostatic charge dissipation. The housing is rated for Type 4X and IP66 environments, providing protection against hose-directed water, dust, and severe weather conditions. The 330881-16-04-132-03-02 includes a 3300 XL 8mm probe with connector protector (option 16) and a 13.2-inch sleeve length with M24 x 1.5 mounting threads and Neoprene O-ring for secure installation.
The 330881-16-04-132-03-02 carries extensive hazardous area certifications including North America Ex ia IIC T4/T5 (Class I Zone 0/Division 1), Europe EEx ia IIC T4/T5, and IECEx ia IIC certifications. The system has entity parameters of Ui=-28V, li=140mA, Pi=0.84W, and is temperature classified T1 through T5 depending on ambient conditions. These approvals make the 330881-16-04-132-03-02 suitable for installation in refineries, petrochemical plants, and other potentially explosive atmospheres.
The 330881-16-04-132-03-02 Bently Nevada Proximity Transducer may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Radial Vibration Measurements: It tracks high-speed dynamic shaft displacement (orbit analysis) to spot balance flaws, structural misalignment, or bearing stability issues.
- Axial (Thrust) Position Monitoring: It calculates slow-moving axial drift of thrust collars to prevent devastating internal rotor-to-stator contact.
- Tachometer & Keyphasor Timing: It acts as a high-precision phase-reference indicator to measure shaft rotational speed and pin down exact vibration phase angles.
- Housing Material Matrix: The enclosure is molded from advanced Polyphenylene Sulfide (PPS) thermoplastic infused with glass and conductive fibers. This blend maximizes physical strength and actively dissipates electrostatic charges.
- Environmental Ratings: The casing holds NEMA Type 4X and IP66 ratings, shielding internal electronics against high-pressure water jets, dust ingress, and harsh airborne chemicals.
- Operating Range: Safe for continuous operation from -51 °C to +100 °C (-60 °F to +212 °F).
- Storage Bounds: Can be stored from -51 °C to +105 °C (-60 °F to +221 °F).
- Direct Signal Conversion: Operating on the eddy-current principle, the unit outputs a standard negative DC/AC voltage proportional to the distance from the target (calibrated for AISI 4140 steel), typically scaled at 200 mV/mil (7.87 V/mm).
- Simplified Field Wiring: Because the Proximitor preamp is built into the housing cap, field wires connect straight from the asset to the monitoring room without intermediate terminal blocks.
- Machinery Protection Hooks: The output feeds directly into protection machinery like the Bently Nevada 3500 Monitoring Rack. The rack processes these signals to trigger ALERT indicators for maintenance and DANGER relays to activate automatic emergency machine shutdowns (Trips).
- Asset Condition Assessment: Beyond raw hardware loops, the dynamic signal streams directly into predictive maintenance software platforms, such as Bently Nevada System 1, allowing plant operators to view real-time orbits, trend lines, and spectrum plots.
