The 330105-02-12-10-02-05 is a core component of the Bently Nevada 3300 XL 8 mm proximity transducer system.It operates as a vital non-contact displacement sensor within predictive maintenance frameworks.
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 rotor axial differential expansion and shaft vibration in steam turbine-generator sets at large thermal power plants to prevent impact and wear between high-speed rotating blades and casings.
Oil & Gas
Installed on fluid-film bearings of natural gas centrifugal compressors in long-distance pipelines to measure dynamic shaft vibration under continuous high-pressure operation.
Petrochemical & Refining Industry
Used for Keyphasor speed measurement and shaft orbit condition analysis on high-speed rotor assemblies within hydrocracking and catalytic cracking units.
Steel & Metallurgical Industry
Monitors bearing displacement on high-pressure, high-power blast furnace blowers and Top Gas Recovery Turbine (TRT) systems, ensuring equipment operational safety in high-dust environments.
Hydroelectric Power Industry
Monitors the shaft swing (radial vibration) of large-diameter main shafts in hydro-generator sets (including pumped storage units) and dynamic gap variations of thrust bearings.
Pulp & Paper Industry
Monitors non-contact bearing conditions of high-speed input shafts on yankee dryer gearboxes and large exhaust fans in modern paper mills to reduce unplanned downtime rates.
During use, the 330105-02-12-10-02-05 probe requires precise installation clearance calibration, typically targeting a native -10 Vdc gap voltage to ensure it operates within its 2.0 mm linear range. Given its 1.0-meter integrated cable, it must be strictly paired with a 4.0-meter or 8.0-meter extension cable to match the total electrical length requirement of 5-meter or 9-meter Proximitor systems; altering the cable length will compromise measurement accuracy. Additionally, operators must maintain a minimum cable bend radius of 25.4 mm, utilize connector protectors against fluid contamination, and strictly adhere to hazardous area instructions to maintain its intrinsically safe certifications.
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. Engineered for specialized installations, this model features a reverse mount structure with 3/8-24 UNF threads, a 0.2-inch unthreaded length, and a 1.2-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 Reverse Mount Probe manufactured by Bently Nevada.
What is the physical mounting method for 330105-02-12-10-02-05?
It utilizes a Reverse Mount design, threading in from the rear side of the bracket or sleeve, suitable for areas with tight external adjustment space.
How to use products like 330105-02-12-10-02-05?
Thread it reversely into the bearing housing to maintain a proper gap between the tip and the metal shaft, extend its 1-meter cable using an extension cable, and connect it to a Proximitor to output voltage signals.
What kind of cable connector does 330105-02-12-10-02-05 have?
It is equipped with a miniature coaxial ClickLoc premium connector at the end of the 1-meter cable, featuring self-locking anti-loosening and industrial fluid resistance.
How to match the extension cable when using 330105-02-12-10-02-05?
Since the probe has a 1-meter integrated cable, it must be paired with a 4.0-meter extension cable for a standard 5-meter system, or an 8.0-meter extension cable for a 9-meter system.
