The 330101-14-30-10-02-05 is a 3300 XL series 8mm eddy current proximity probe manufactured by Bently Nevada (a Baker Hughes business). As a core sensor for industrial rotating machinery condition monitoring, it delivers high-precision, non-contact measurements of shaft vibration, axial displacement, and keyphasor signals.
One 3300 XL 8 mm probe
One 3300 XL extension cable
One 3300 XL Proximitor Sensor
The 3300 XL 8 mm system delivers the most advanced performance in our eddy current proximity transducer systems. The standard 3300 XL 8 mm 5-meter system also fully complies with the American Petroleum Institute’s (API) 670 Standard for mechanical configuration, linear range, accuracy, and temperature stability. All 3300 XL 8 mm proximity transducer systems provide this level of performance and support complete interchangeability of probes, extension cables, and Proximitor sensors, eliminating the need to match or bench calibrate individual components. Each 3300 XL 8 mm Transducer System component is backward compatible and interchangeable with other non XL 3300 series 5 mm and 8 mm transducer system components. This compatibility includes the 3300 5 mm probe, for applications in which an 8 mm probe is too large for the available mounting space.

Power Generation
Monitors shaft radial vibration and axial displacement of large steam turbine-generator sets to prevent rotor-to-stator rubs caused by sudden load changes.
Nuclear Power
Applied in bearing vibration monitoring of nuclear island main feedwater pumps and reactor coolant pumps to ensure the absolute safety of the nuclear cooling loop.
Oil & Gas
Installed on natural gas export compressors of offshore drilling platforms to monitor high-speed main shaft status and prevent unexpected downtime in harsh marine environments.
Petrochemical
Measures axial thrust and differential expansion of cracked gas compressors and hydroprocessing feed pumps; its hazardous area approvals (-05 option) ensure safety in volatile chemical environments.
Pipeline Transportation
Used in gas turbine-driven compressor trains at long-distance natural gas pipeline compressor stations to provide remote condition monitoring and protection for midstream transport equipment.
During use, ensure the probe tip is perpendicular to the AISI 4140 calibrated steel shaft, and precisely adjust the initial gap voltage (typically -10 Vdc) using the Proximitor. Coaxial connectors must be strictly protected from oil and moisture using insulating sleeves. Avoid over-bending or pulling the cables. Furthermore, this probe cannot be mixed with 3300 series (non-XL version) or 5mm/11mm systems to prevent signal distortion.
Driven by an external Proximitor sensor, this system provides an output voltage that is directly proportional to the distance between the 8 mm probe tip and the observed conductive surface and can measure both static (position) and dynamic (vibration) values. Formulated for standard case installations, this model features an imperial thread structure with 3/8-24 UNF threads, a 1.4-inch unthreaded length, and a 3.0-inch overall case length. It delivers signals via a 1.0-meter integrated cable fitted with a fluid-resistant, self-locking ClickLoc premium coaxial connector, and it carries global hazardous area agency approvals (CSA, ATEX, IECEx). When fully deployed, the system’s primary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor reference and speed measurements.
It is a Bently Nevada 3300 XL series 8 mm eddy current proximity probe. This model is a non-contact displacement sensor designed for continuous monitoring of shaft vibration, axial displacement, and speed of industrial rotating machinery.
How to correctly install and use the 330101-14-30-10-02-05 probe?
Thread the probe into the bearing housing, aligning it with the shaft, setting the correct gap, and using it with a 3300 XL Proximitor sensor.
How does the 330101-14-30-10-02-05 work?
It operates on the eddy current principle, where high-frequency electromagnetic fields interact with the metallic shaft surface, changing system impedance to convert gap variations into voltage output.
What target material is the 330101-14-30-10-02-05 calibrated to by default?
It is factory-calibrated by default to AISI 4140 steel. Measuring other metals like stainless steel or aluminum requires recalibration.
What should be noted when connecting the 330101-14-30-10-02-05 connector?
The coaxial connector must be kept clean from oil and water to avoid signal drift, using connector protective sleeves in harsh environments is highly recommended.
