The 330901-05-65-05-11-05 is a Bently Nevada 3300 XL NSv non-contacting eddy-current proximity probe. The part number defines its hardware specifications. Within this code, 330901 indicates a 1/4-28 UNF threaded unarmored model. The first 05 denotes a 0.5-inch unthreaded length. The 65 specifies a 6.5-inch overall case length. The second 05 indicates a 0.5-meter cable length. The 11 specifies a fluid-resistant FluidLoc cable with a miniature ClickLoc connector and protector. The trailing 05 denotes multi-agency hazardous area approvals.
Axial (thrust) position measurements
Phase reference (Keyphasor signals)
Tachometer and zero speed measurements
The 3300 XL NSv Proximity Transducer system is intended for use with centrifugal air compressors, refrigeration compressors, process gas compressors, and other machines with tight installation requirements. The primary uses for the 3300 XL NSv Transducer System are for areas where counterbore, sideview, or rearview restrictions limit the use of standard Bently Nevada 3300 and 3300 XL 5 and 8 mm Transducer Systems. It is also ideal for small target applications, such as measuring radial vibration on shafts smaller than 51 mm (2 in) or axial position on flat targets smaller than 15 mm (0.6 in).
This system delivers an Average Scale Factor of 7.87 V/mm (200 mV/mil) with a linear measurement range of 1.5 mm (60 mils). The 3300 XL NSv Transducer System design allows it to replace both the legacy 3300 RAM Transducer Systems and the 3000-series or 7000-series 190 Transducer System. Upgrades from the 3300 RAM system to the 3300 XL NSv system may reuse the existing RAM probe and extension cable when connected to a new 3300 XL NSv Proximitor Sensor. Upgrades from the 3000-series or 7000-series Transducer System must replace the probe, extension cable, and Proximitor Sensor entirely with NSv components to maintain accurate calibration.

When operating and replacing the 330901-05-65-05-11-05, field personnel must fully verify its technical ordering code and hazardous-area approval requirements prior to installation. It is critical to validate the 1/4-28 UNF mounting threads, confirm sufficient machine-case clearance, and match the target shaft material alongside specific probe gap voltage requirements.
Given the lengthy 6.5-inch overall case dimensions of this specific model, additional sleeve support must be implemented to ensure mechanical rigidity and prevent structural vibration. Furthermore, this integrated probe assembly must never be treated or cross-used as a standard NSv extension cable within the measurement loop.
The 330901-05-65-05-11-05 utilizes the patented TipLoc molding technology to achieve a high-strength mechanical bond between the probe tip and the probe body, while combining a CableLoc structural design that allows the connection between the probe cable and the probe tip to withstand an axial pull strength of at least 220 N (50 lb), which effectively prevents signal interruptions caused by pulling in harsh industrial environments.
It is a Bently Nevada 3300 XL NSv series non-contacting eddy-current proximity probe.
What is the primary measurement use of 330901-05-65-05-11-05?
