The 330101-00-39-15-11-00 is an 8mm non-contact eddy current proximity probe from the 3300 XL series, specifically designed for critical monitoring of rotating machinery. It is widely used in industry for high-precision measurement of radial vibration, eccentricity, rotational speed, and axial displacement of shafts.
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.

Nuclear Power
Monitoring the mechanical condition of main feedwater pumps and condensate pumps in the conventional island, providing highly reliable Keyphasor and speed measurements.
Thermal Power
Monitoring the radial vibration and shaft eccentricity of large steam turbine generators to prevent rotor-to-stator rub caused by uneven thermal expansion.
Pulp & Paper
Monitoring the radial and axial vibration of high-speed paper machine dryer gearboxes and large pulper rotors; its tip can penetrate oil films directly for precise measurements.
Petrochemical & Refining
Monitoring the axial thrust displacement of critical machinery like cracking gas compressors and rich gas compressors to prevent catastrophic failures from thrust bearing collapse.
Hydroelectric Power
Monitoring the shaft swing of guide bearings and leveling displacement on vertical hydro-generator units, withstanding internal steam and moisture conditions.
When using the Bently Nevada 330101-00-39-15-11-00 probe, you must accurately adjust the initial gap voltage to the linear center (typically -10 Vdc) with the machine at rest, lock it with a torque of 11.3 N·m to avoid any rotor rub, and never cut the integrated 1.5m cable, as it must match specific extension cables and Proximitors for a strict 5m or 9m system length. Additionally, the ClickLoc coaxial connector must be sealed with a dedicated protector against moisture/oil, and the cable must be routed with a minimum bend radius of 25.4 mm, secured inside protective conduits away from sharp edges and electromagnetic interference.
It is a 3300 XL series 8 mm eddy current proximity probe manufactured by Bently Nevada for non-contact machinery condition monitoring.
What is the core working principle of this type of product, such as 330101-00-39-15-11-00?
The high-frequency coil at the probe tip generates an alternating electromagnetic field. Eddy current losses on the target metal shaft vary with the gap, transforming into a voltage signal proportional to the distance.
How to properly install and adjust 330101-00-39-15-11-00?
Thread it into the mounting bracket, use the Proximitor sensor to measure the output gap voltage while the machine is at rest (typically adjusted to a center value of -10 Vdc), and then secure it with a locknut.
What components must this type of product, such as 330101-00-39-15-11-00, be used with?
It cannot work alone, it must connect to a 3300 XL extension cable (to form a 5m or 9m system) and plug into a 3300 XL Proximitor Sensor.
If the probe tip of 330101-00-39-15-11-00 gets dirty and covered with oil, will it affect its measurement accuracy?
No, this eddy current sensor penetrates non-conductive mediums such as oil, water, steam, and dust, allowing it to measure the metallic shaft surface directly through the oil film.
