The 330103-00-05-10-02-00 is an imperial eddy current proximity probe for the 3300 XL 8mm system, featuring a 3/8-24 UNF thread, 0.5" unthreaded length, 1.0" overall case length, and a 0.5m unarmored cable. It fully complies with the API 670 standard, offering a 2.0 mm (80 mils) linear range and 100% calibration-free interchangeability. This product is primarily used for non-contact precise monitoring of radial vibration, axial position, speed, and Keyphasor references on large rotating machinery such as turbines and compressors.
One 3300 XL 8 mm probe
One 3300 XL extension cable
One 3300 XL Proximitor Sensor
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 system’s 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 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.

Oil & Gas Refining
Monitors shaft vibration of core hydrocracking compressors and high-pressure oil pumps in catalytic cracking units.
Thermal Power Generation
Monitors the axial displacement (position) of large steam turbine generator shafts to prevent catastrophic axial movement and thrust bearing failure.
Hydroelectric Power Generation
Installed on hydro-turbine generator shafts to measure shaft runout (radial vibration) and thrust clearance.
Nuclear Power Generation
Monitors bearing conditions and Keyphasor references of giant main steam turbines and reactor coolant pumps (RCPs) in the conventional island.
Iron & Steel / Metallurgy
Monitors the dynamic vibration and speed of blast furnace blowers and large converter gas fans.
Mining & Mineral Processing
Monitors high-power gearbox input bearings of large ball mills and SAG mills in mineral processing plants.
When installing and operating the 330103-00-05-10-02-00 probe, the following critical precautions must be strictly observed: First, since the native cable is only 0.5 meters long and unarmored, external protective conduits must be installed to prevent mechanical wear, and it must be paired strictly with a 4.5-meter extension cable to maintain the 5-meter system's measurement accuracy.
Second, during installation, use a multimeter to monitor the Proximitor output and precisely set the initial gap to the linear midpoint (typically -10 Vdc).
Lastly, avoid any impact on the probe tip, do not overtighten the threads during mounting, and ensure the target shaft material is standard AISI 4140 steel with a smooth, scratch-free, and demagnetized surface to prevent severe reading distortions.
Bently Nevada 330103-00-05-10-02-00 is an imperial eddy current proximity probe for the 3300 XL 8mm system, featuring a 3/8-24 UNF thread, 0.5" unthreaded length, 1.0" overall case length, and a 0.5m unarmored cable.
330103-00-05-10-02-00 is a 3300 XL 8 mm Proximity Probes.
What is the principle of the 330103-00-05-10-02-00 probe?
Proximity sensors detect objects without touching them. They operate using principles like electromagnetic induction (inductive), changes in capacitance (capacitive), reflection of ultrasonic waves (ultrasonic), or interruption of light beams (photoelectric).
How to use 330103-00-05-10-02-00?
It must be rigidly mounted on the machine bearing housing or a dedicated bracket, aligning the probe tip perpendicularly to the rotating shaft surface. The cable must connect to a 3300 XL extension cable and a 3300 XL Proximitor sensor (5-meter system), then route the signal to a Bently Nevada 3500 monitoring system for data acquisition.
What are the primary applications of 330103-00-05-10-02-00?
It is primarily used for radial vibration and axial position measurements on fluid-film bearing machines (such as steam turbines, compressors, hydro turbines, large fans), as well as for Keyphasor reference and speed measurements.
What industrial standards does 330103-00-05-10-02-00 comply with?
When combined as a complete 3300 XL 8 mm 5-meter system, it fully complies with the American Petroleum Institute's API 670 standard for mechanical configuration, linear range, accuracy, and temperature stability.
