Product Description
330881-16-11-165-07-02 Bently Nevada PROXPAC XL Proximity Transducer Assembly For Machinery Condition Monitoring Applications
Engineered as a fully self-contained sensor pod with an extra-long 16.5-inch rigid sleeve penetration, the Bently Nevada 330881-16-11-165-07-02 integrates the proximity probe and driver circuitry directly onto the machine case. It completely eliminates the costly procurement, fragile coaxial cable routing, and high failure rates associated with remote, externally paneled Proximitor sensor boxes in hazardous environments. This high-density, multi-certified layout makes it the definitive choice for critical shaft vibration tracking on massive, double-walled steam turbines and heavy centrifugal compressors within chemical processing and power generation plants.
Core Parameters and Value Benefits
-
Integrated 3300 XL 8 mm Proximity Transducer System (Option 16)Combines the probe, extension cable, and driver circuitry into one field-replaceable, weatherproof pod. Traditionally, you must source three separate components and mount the fragile Proximitor sensor inside a remote electrical box. This integrated layout eliminates up to 4 potential wire-termination failure points, slashing installation time by 60% and ensuring that raw machinery vibration signals are processed directly at the machine case without signal attenuation.
-
16.5-Inch Sleeve Penetration Length (Option 165)Safely bridges extreme gaps between massive, double-walled machinery casings and internal shafts. Large-scale steam turbines or high-capacity centrifugal compressors feature extraordinarily thick outer shells and heavy thermal insulation blankets. A precise 16.5-inch rigid steel sleeve ensures the probe tip flawlessly hits its target measurement plane inside the bearing house, without the risk of long-lead sagging or oil-splash deflection.
-
Low-Profile 3/4-14 NPT Threaded Glass-Reinforced Enclosure (Option 02)Provides structural immunity to aggressive chemical corrosion and high-pressure washdowns. The durable, heavy-duty casing completely seals fragile internal electronics against high-humidity steam, corrosive cooling-tower spray, and volatile oil fumes. This keeps your safety-critical machinery condition monitoring loops online for decades, preventing costly, unexpected sensor-drift replacements in hazardous environments.
Engineer's Note: "Our chief vibration instrumentation engineer suggests selecting this 330881-16-11-165-07-02 model if your bearing housing features deep thermal insulation scaling over 14 inches. Because of its structural 16.5-inch sleeve penetration, it bypasses external shell clearance limits entirely; however, we strongly advise installing an internal sleeve guide within the turbine casing to suppress probe-tip resonance caused by high-velocity oil currents inside the machine cavity."
Frequently Asked Questions
Can the internal proximity probe of the PROXPAC XL 330881 be replaced without dismantling the entire housing assembly?
Yes, the 330881 architecture features a unique reverse-mount mechanical core that allows field technicians to unbolt the upper pod cap and pull out the sensor probe directly through the top, entirely avoiding the need to remove the mounting flange or drain the machine oil.
Does the integrated driver system inside this assembly require a separate external Proximitor box?
No, the PROXPAC XL is completely self-contained, housing both the 3300 XL eddy current probe and its corresponding driver circuitry inside the top pod, which outputs a direct dynamic voltage signal straight to your machinery protection system.
How do you verify the signal calibration of a long 16.5-inch penetration probe before field deployment?
All units sourced through our verified network undergo dynamic calibration mapping on specialized Bently Nevada spindle rigs, checking the linear range across a full 80-mil (2 mm) gap envelope to guarantee zero signal drift or calibration errors.
