The 330880-28-15-048-00-02 is a Bently Nevada integrated proximity probe housing featuring a built-in 3300 XL Proximitor sensor and advanced glass-reinforced PPS thermoplastic construction. Fully eliminating the need for separate extension cables or remote enclosures, this self-contained unit connects field wiring directly to the monitor to deliver simplified, space-saving vibration tracking in severe Type 4X and IP66 industrial environments.
Features and benefits
- Built-in Proximitor sensor – No separate housing or extension cable, reducing installation complexity.
- PPS thermoplastic enclosure – Rated Type 4X and IP66 for corrosion resistance and hose-directed water protection.
- Multiple hazardous area approvals (AA=28) – Suitable for ia, nA, ec installations per ATEX/IECEx/cNRTLus.
- 1.5” standoff adapter (BB=15) – Positions probe away from machine case for flexible mounting.
- 4.8” probe penetration (CCC=048) – Reaches deep targets while staying under the 12” sleeve support limit.
- 3/4-14 NPT mounting thread (EE=02) – Standard thread ensures rigid, secure installation.
System Compatibility & Alternative Models
- System Compatibility: Fully replaces the combined setup of a separate 3300 XL 8mm probe, an extension cable, and a standalone Proximitor sensor. Output signals are fully standard and route directly over standard 16 to 24 AWG field wiring to Bently Nevada 3300 or 3500 monitoring racks.
- Alternative Model (Standard Split-System Configuration): 31000 or 32000 Proximity Probe Housing Assemblies.
- Difference: The PROXPAC XL integrates the Proximitor sensor right inside its own lid cover to establish a direct internal connection. The 31000/32000 series are passive mechanical sleeves that require routing a separate, vulnerable coaxial extension cable out to a standalone remote Proximitor sensor box.
- Alternative Model (Metric Infrastructure Variation): 330881 Proximity Transducer Assembly.
- Difference: The 330880 model uses English sizing parameters (inches, NPT conduits/threads). The 330881 architecture is built explicitly on metric dimension benchmarks, introducing M25 or M20 metric wiring conduits alongside metric outer body sleeve casings.
