Features:
- Integrates probe and Proximitor sensor in one housing, eliminating extension cables.
- Durable thermoplastic with glass fibers, protected against severe environments.
- Ex ia IIC and IECEx certified for Zone 0/Division 1 explosive atmospheres.
The 330880-28-15-042-00-02 is a completely self-contained proximity probe system that integrates the 3300 XL Proximitor sensor directly into the housing cover. This innovative 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 330880-28-15-042-00-02 also eliminates the need for a separate Proximitor housing, as field wiring connects directly between monitors and the PROXPAC XL assemblies. This design simplifies installation, reduces maintenance complexity, and minimizes the risk of connection-related failures in critical machine monitoring applications.
The 330880-28-15-042-00-02 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 330880-28-15-042-00-02 is rated for Type 4X and IP66 environments, providing protection against hose-directed water, dust, and severe weather conditions. The housing has been certified to withstand two separate 4 Joule impacts at -39°C and 115°C, and CSA-verified 7 Joule impacts at ambient temperature. This durability makes the 330880-28-15-042-00-02 suitable for demanding industrial environments including offshore platforms, chemical plants, and outdoor installations.
The 330880-28-15-042-00-02 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 330880-28-15-042-00-02 also supports nA/nL (non-sparking) installations for Zone 2/Division 2 when installed without barriers. The 330880-28-15-042-00-02 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 330880-28-15-042-00-02 suitable for installation in refineries, petrochemical plants, and other potentially explosive atmospheres.
The 330880-28-15-042-00-02 Bently Nevada Proximity Transducer may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Thrust (Axial) Position Monitoring: Primarily deployed on massive steam turbines and gas turbines (such as GE Frame 9 units) to track critical thrust collar movement and protect against internal rotor-to-stator contact.
- Differential Expansion (DE): Installed on utility-scale steam turbines to measure the relative thermal growth differential between the turbine rotor and the outer casing during startup and shutdown cycles.
- Large Journal Bearings: Monitors radial shaft vibration and shaft centerline position in high-power, slow-to-medium speed rotating machinery like large industrial fans, water pumps, and hydro-turbines.
- Reciprocating Compressor Rod Drop: Measures the dynamic rod position in large piston compressors to actively monitor rider band wear.
- Coaxial Loop Interconnects: The Proximitor connects to the probe assembly via miniature ClickLoc coaxial connectors. The impedance of the cable structure is carefully controlled.
- Calibration Specification (The 4.2-Meter Rule): The sub-code -042 in your model string specifies a 4.2-Meter Total System Length. This means the Proximitor is factory-tuned to expect exactly 4.2 meters of total electrical cable length between the sensor tip and the Proximitor box.
- BNC Interface: Includes a front-panel raw analog BNC connector, allowing vibration engineers to attach portable data collectors (such as a Bently Nevada SCOUT or an oscilloscope) for diagnostic waveform and orbit analysis without interrupting the primary protection loop.
- Hazardous Area Approvals (The -02 Option): The suffix -02 designates multi-national Approvals Option for ATEX, IECEx, and North American (CSA/FM) certifications. This allows the device to be installed in Zone 0, Zone 1, or Class I, Division 1 hazardous environments using intrinsic safety barriers or explosion-proof enclosures.
- Electrical Isolation: The Proximitor base plate is designed with integrated structural isolation. It can be mounted directly onto aluminum DIN rails or flat panels without requiring separate non-conductive isolation plates, mitigating the risk of structural ground loops.
- Scale Factor Integrity & Diagnostics: Delivers a standardized linear scale factor of 100 mV/mil (3.94 V/mm). The Proximitor continuously conducts loop-integrity diagnostics. If a field cable becomes crushed or disconnected, it shifts the supply current outside normal bounds, instantly triggering a "Not OK" status fault at the monitoring rack to suppress false emergency trip commands.
