The 330880-28-15-027-00-02 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
-
2.7” probe penetration (CCC=027) – Ideal for machines with limited internal clearance or thin casings.
-
1.5” standoff adapter (BB=15) – Provides offset mounting without requiring custom machining.
-
No conduit fittings (DD=00) – Simplifies installation when using flexible conduit or direct sealing.
-
±0.5” adjustment range – Threaded sleeve allows fine tuning of gap after installation.
-
No sleeve support needed – Total B+C = 4.2” (1.5+2.7), well below the 12” resonance threshold.
-
IP66 & Type 4X housing – Withstands hose-directed water, dust, and corrosive environments.
Specific Application
- Self-Contained Remote Monitoring: Optimized for isolated machinery installations where mounting space is limited and a separate, distant Proximitor housing cannot be accommodated.
- Corrosive Chemical & Wet Environments: Ideal for cooling towers, water washdown zones, and petrochemical processing plants requiring high IP66 dust/water sealing and Type 4X corrosion protection.
- External Access Machinery Gapping: Engineered for deep casing installations on high-speed pumps or gearboxes where technicians need to adjust sensor gaps externally without machine disassembly.
