The 330104-00-20-10-02-05 is a Bently Nevada 3300 XL series 8mm eddy current probe (forward mounting). This model is a standard sensor for industrial applications, and its fully threaded and explosion-proof configuration offers high flexibility for installation on various rotating machinery.
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.

Oil & Gas Industry
Installed on centrifugal compressors in oilfield units. Used in conjunction with probe housings to monitor radial vibration, ensuring safe operation in high-pressure natural gas environments thanks to its explosion-proof ratings.
Thermal Power Generation
Used for steam turbine thrust bearing monitoring. It measures axial displacement (thrust) and triggers automatic trip protection if rotor displacement exceeds safety limits due to pad wear.
Petrochemical Industry
Monitors the shaft centerline orbit in ethylene cracked gas compressors. The ATEX/IECEx certifications ensure intrinsic safety in explosive chemical environments.
Hydro Power Generation
Installed on the guide bearings of hydro turbines. Used with sealed housings to measure the oscillation of large-diameter, low-speed shafts, preventing severe vibration caused by hydraulic imbalance.
Metallurgy Industry
Applied to blast furnace blowers. In high-dust and high-temperature environments, the probe is sealed within a protective housing to monitor oil film status and prevent motor bearing burnout.
When using the 330104-00-20-10-02-05 probe, it must be used in an explosion-hazardous area with an intrinsically safe safety gate and a dedicated probe housing. During installation, the output must be monitored using a multimeter, and the initial gap must be precisely locked at approximately -10V at the linear midpoint. It is strictly forbidden to cut the 1.0 meter of the integrated cable to maintain system impedance matching. Simultaneously, the probe head should be protected from mechanical impact, and the coaxial connector should be properly insulated and sealed against moisture to ensure signal stability under harsh operating conditions.
The 330104-00-20-10-02-05 is a 3300 XL series 8 mm Eddy Current Proximity Probe manufactured by Bently Nevada. It is a non-contacting sensor specifically used to measure shaft vibration, displacement, and keyphasor on large rotating machinery.
How to use products like the 330104-00-20-10-02-05?
To use it, thread it into the machine's bearing housing or mounting bracket so that the probe tip directly faces the rotating shaft surface, and adjust the thread depth to ensure the initial installation gap is within the linear region. It cannot be used alone and must be connected to a 3300 XL Proximitor via a 3300 XL extension cable.
What is the primary function of the 330104-00-20-10-02-05 in the system?
Its primary function is serving as the "sensor" for the monitoring system, converting minute dynamic or static displacements on the shaft surface into electrical signals without contact via the eddy current principle, enabling real-time monitoring of bearing vibration and axial shift.
How to determine if the 330104-00-20-10-02-05 is damaged?
After disconnecting the extension cable, measure the resistance between the center pin and the outer shell of the probe's ClickLoc connector using a multimeter. The normal coil resistance for 3300 XL series probes is typically between 5.0 and 12.0 ohms; infinity or near zero indicates damage.
What should be paid attention to in the daily maintenance of the 330104-00-20-10-02-05?
The maintenance focus is on keeping the ClickLoc connector clean and never letting oil or dust contaminate its interior, which affects measurement accuracy; additionally, sharp bends in the cable must be avoided, keeping the bend radius above 25.4 mm.
