The 330101-12-28-10-02-00is an 8mm eddy current probe from the 3300 XL series manufactured by Bently Nevada. As a standard sensor for monitoring industrial rotating machinery, it accurately measures shaft vibration and displacement in a non-contact manner.
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.

Thermal Power Generation Industry
Installed on steam turbine main bearings to monitor radial vibration of the rotor, preventing severe vibrations caused by shaft unbalance.
Oil & Gas Industry
Used for thrust bearing monitoring of large centrifugal compressors to measure axial displacement, preventing rotor-stator collision due to sudden load changes.
Petrochemical Industry
Used in reciprocating compressors to measure Rod Drop, evaluating the wear of internal rider bands by monitoring the piston rod position.
Hydro Power Industry
Installed on the guide bearings of large hydro-generator sets to monitor the radial runout of large-diameter, low-speed shafts.
Air Separation Industry
Used as a Keyphasor sensor in oxygen/nitrogen compressors to provide precise speed signals and phase references.
When using the 330101-12-28-10-02-00 probe, it must be ensured that it is used only in non-explosive hazardous areas (as it lacks explosion-proof certification). Utilize its 1.2-inch threadless section and long shell for deep-hole installation. During installation, monitor with a multimeter to precisely lock the initial clearance at approximately -10V, the linear midpoint. Do not cut the 1.0-meter of the integrated cable to maintain system impedance matching. Protect the probe head from mechanical impact and ensure proper insulation and moisture-proof sealing of the coaxial connector to guarantee signal stability in oily or humid conditions.
The 330101-12-28-10-02-00 is a 3300 XL series 8 mm Eddy Current Proximity Probe manufactured by Bently Nevada.
How to use products like the 330101-12-28-10-02-00?
To use it, it needs to be threaded into the machine's bearing housing or a dedicated probe bracket. The probe tip must face the metal surface of the rotating shaft and maintain a specific initial installation gap. It cannot work alone and must be connected to a 3300 XL Proximitor via an extension cable.
What is the primary function of the 330101-12-28-10-02-00 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 330101-12-28-10-02-00 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 330101-12-28-10-02-00?
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.
