The 330103-00-05-90-12-00 is a standard 8 mm metric proximity probe belonging to the Bently Nevada 3300 XL series. This specific model features an M10 by 1 thread, a 50 mm case length, and an extended 9.0 meter total cable length equipped with a miniature coaxial ClickLoc connector. It is uniquely configured with a FluidLoc cable to prevent oil or other fluids from leaking out through the inside of the cable.

50 mm Metric Fully Threaded Configuration (M10×1)
Cross-Generational System Upgrade with Asset Reuse
Operating on eddy current principles, the system provides an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface and can measure both static position and dynamic vibration values. The primary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor reference and speed measurements.
The 3300 XL 8 mm system delivers the most advanced performance in our eddy current proximity transducer systems.The standard 3300 XL 8 mm 9-meter system configuration also fully complies with the American Petroleum Institute 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 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.

Oil & Gas Exploration
Used inside large long distance oil pipeline pumps and LNG centrifugal compressors, where the fluid proof cable completely prevents high pressure crude oil or liquefied gas from leaking outward along the coaxial cable.
Petrochemical & Refining
Installed inside the high temperature lube oil sumps of ethylene charge gas compressors and hydrotreating feed pumps, where the long cable routes directly outside the machine casing while blocking hot oil migration.
Thermal Power Generation
Monitors the radial vibration of supercritical steam turbine generator shafts, where the 9.0 meter long cable allows direct routing from inside the bearing housing to the high pressure Proximitor protective box on the machine side.
Nuclear Power Generation
Utilized for main feed pumps and heavy rotating auxiliary units in nuclear islands, where the fluid proof feature effectively isolates the spread of media containing radioactive steam or oil contamination.
Hydroelectric Power Generation
Monitors the axial displacement of thrust bearings in large vertical hydro generator units, where its special sealed cable structure provides long term resistance to high humidity and water mist environments.
Steel & Metallurgy
Used for monitoring lubricated bearings in high power blast furnace blowers and large gearboxes on hot rolling lines, where the fluid proof cable protects precision signals from contamination in oil rich and dusty environments.
During installation, precisely adjust the initial gap to the center of its linear range, typically corresponding to minus 10 Vdc, and maintain a side clearance of at least twice the probe tip diameter to eliminate electromagnetic interference from surrounding metals. Avoid excessive pulling during routing and ensure the bend radius of its long cable remains above 25.4 mm. Benefiting from the integrated 9.0 meter FluidLoc cable, the Miniature Coaxial ClickLoc connector must be kept completely clean and dry before connection, and it must be tightened by hand only—never use tools.
Lastly, this probe must connect directly to a matching 9 meter system Proximitor sensor, and it is strictly forbidden to mix it with a 5 meter system Proximitor or add an extra extension cable, as this will cause severe measurement errors.
The 330103-00-05-90-12-00 configuration features a 50mm metric M10×1 threaded case, an extended 9.0-meter integrated cable with stainless steel armored protection, and a fluid-sealed ClickLoc connector for harsh industrial environments.
It is a Bently Nevada brand 3300 XL series 8 mm metric proximity probe, primarily used to measure shaft vibration and shaft displacement of rotating machinery.
What is the operating principle of 330103-00-05-90-12-00?
It operates on the eddy current principle, using a high frequency electromagnetic field emitted from the probe tip to interact with the target metal surface, outputting an analog voltage signal proportional to the gap distance.
How to correctly use products like 330103-00-05-90-12-00?
It must be threaded into the probe mounting hole on the rotating machinery bearing housing with the probe tip facing the shaft surface, and the other end must connect directly to a matching 9 meter Proximitor sensor.
What is the linear range of the 330103-00-05-90-12-00 probe tip?
Its linear range is 2.0 mm, which is equivalent to 80 mils.
What material is the probe tip of 330103-00-05-90-12-00 made of?
Its probe tip is made of polyphenylene sulfide, which is a high performance insulating engineering plastic.
