The 330103-02-10-10-01-CN is a 3300 XL series 8mm high-precision non-contact eddy current proximity probe manufactured by Bently Nevada, USA. As a core sensing component in condition monitoring systems for large rotating machinery, it is primarily used for continuous online measurement of radial shaft vibration and axial displacement.
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.

Thermal Power
Screwed forward into an external bracket via its M10 metric thread to accurately measure the radial shaft vibration of high-speed power plant feedwater pumps, preventing bearing pad wear.
Petrochemical
Used for continuous monitoring of the axial thrust position of main shafts in large centrifugal compressors within hydrocracking units.
Hydroelectric Power
Forward-mounted on the side of thrust bearing housings in vertical hydroelectric generator units to capture low-frequency shaft swing and eccentricity variations in real time.
Coal Chemical Industry
Functions as a phase reference sensor on large air separation or methanol synthesis compressors, utilizing its 0 Hz to 10 kHz wide frequency response for high-precision Keyphasor measurements.
Nuclear Power
Used for radial vibration measurement on the bearing casings of main steam turbine-generator units within the conventional island of nuclear power plants, providing micron-level high-precision protection.
Paper and Pulp Industry
Installed on high-speed paper machine heavy press rolls and drive gearboxes to measure bearing eccentric profiles, ensuring paper thickness uniformity.
Due to its fine M10x1 metric thread, the maximum tightening torque must never exceed 5.6 N·m during installation, and ensure the probe tip is vertically aligned with a clearance zone free of interfering metal measuring at least twice the probe diameter. Since this cable lacks stainless steel armor protection, the bend radius must exceed 25.4 mm with no hard pulling or stepping allowed during routing, and always keep the ClickLoc coaxial connectors clean and dry.
Because the probe comes with a built-in 1.0-meter cable, it must be paired with a dedicated 3300 XL extension cable and Proximitor to match the required total system length—never cut the cable or append non-standard cables, as this will cause signal distortion or complete system failure.
The 330103-02-10-10-01-CN is an 8mm metric forward-mount proximity probe that provides an output voltage directly proportional to the distance between the probe tip and the observed conductive surface when connected to a 3300 XL Proximitor Sensor. It is designed to measure both static (position) and dynamic (vibration) values within a standard 2.0 mm (80 mils) linear range. Featuring an M10×1 threaded case with a 100 mm overall case length (20 mm unthreaded length), this specific configuration integrates a 1.0-meter standard coaxial cable without armor and a ClickLoc coaxial connector with a connector protector. Compliant with China-specific regulatory and hazardous area approvals (CN), the probe's primary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor reference and speed measurements.
It is a 3300 XL series 8mm metric thread forward-mount eddy current proximity probe manufactured by Bently Nevada.
What measurement principle does the 330103-02-10-10-01-CN use?
It uses the high-precision eddy current principle based on a high-frequency electromagnetic field for non-contact gap distance measurement.
How should a forward-mount probe like the 330103-02-10-10-01-CN be used?
The probe is typically screwed directly into an external mounting bracket or sleeve to adjust its gap from the shaft surface.
What are the typical industrial applications of the 330103-02-10-10-01-CN?
It is widely used for radial shaft vibration measurement, axial position monitoring, and Keyphasor measurement on heavy rotating machinery.
Is bench calibration required when using the 330103-02-10-10-01-CN?
No, the 3300 XL series components support complete physical and electrical interchangeability.
