The 330102-10-40-10-02-00 is an 8 mm imperial threaded proximity probe belonging to the Bently Nevada 3300 XL series. This specialized standard configuration features a 3/8-24 UNF thread, a 1.0 inch unthreaded length, a 4.0 inch overall case length, and a 1.0 meter total cable length fully enclosed in a flexible stainless steel armor jacket for premium protection against mechanical crushing and physical abrasion.
Robust Flexible Stainless Steel Armor Protection
API 670 Interchangeability Eliminates Bench Calibration
Advanced Static and Dynamic Measurement Capabilities
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 5-meter system configuration, which can be formed by connecting this 1.0 meter probe to a 4.0 meter extension cable, 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, 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 Industry
It is used to monitor the shaft vibration and axial displacement of large gas turbines, steam turbines, and generators to prevent rotor-to-stator rubbing caused by severe load variations.
Oil & Gas Extraction
It is installed on high-pressure centrifugal compressors and long-distance pumps for natural gas pipelines to monitor rotational speed and bearing wear.
Petrochemical and Refining Industry
It provides real-time monitoring of bearing dynamic balance in heavy critical pumps and charge gas compressors within catalytic cracking and hydrocracking units.
Coal Chemical Industry
It monitors the oil film bearing conditions of ultra-large centrifugal air compressors, boosters, and gasifier axial fans in air separation units.
Hydroelectric Power Industry
It is used to monitor the swing (radial vibration) and axial displacement of hydro-generator units to analyze abnormal vibrations caused by hydraulic imbalance or generator magnetic asymmetry.
Wind Power Industry
It detects bearing clearance changes under low-speed, heavy-load conditions on the main shaft bearings and speed-increasing gearbox input/output shafts of large offshore or onshore wind turbines.
During installation, precisely adjust the initial probe gap to the center of its linear range, typically corresponding to minus 10 Vdc, and maintain a side physical clearance of at least twice the probe tip diameter to eliminate electromagnetic interference from surrounding metals.
During routing, although the cable is protected by an integrated flexible stainless steel armor jacket, excessive pulling and sharp kinks must still be strictly avoided to ensure the bend radius stays above 25.4 mm. Before connecting the Miniature Coaxial ClickLoc connector, the core connecting interface must be kept completely clean and dry, and it must be tightened by hand only—never use any metal tools.
Lastly, since this probe features a 1.0 meter cable, it must be combined with a matching 4.0 meter extension cable to connect to the Proximitor sensor, and it is strictly forbidden to bypass the extension cable or mix it with a 9 meter system Proximitor, as this will cause severe measurement errors.
The Bently Nevada 330102-10-40-10-02-00 is an imperial threaded proximity eddy current probe belonging to the 3300 XL 8 mm series, primarily utilized for axial displacement, radial vibration, and Keyphasor phase reference monitoring of large industrial rotating machinery. Operating on eddy current principles, the product generates a high frequency electromagnetic field from the probe tip to interact with the observed metal shaft surface, providing an analog voltage signal directly proportional to the distance between the probe tip and the target conductive surface while simultaneously measuring both static position and dynamic vibration values.
