Information

Overview Manuals Common Applications Product Precautions
The 330102-00-31-05-02-00 is a 3300 XL 8 mm eddy current proximity probe manufactured by Bently Nevada. This device serves as a high-precision non-contact industrial-grade sensing element widely deployed on high-speed rotating machinery such as steam turbines, gas turbines, large compressors, high-pressure water pumps, and generators to precisely measure dynamic shaft vibration, axial displacement, and rotational speed or Keyphasor signals on fluid-film bearing equipment.
    • 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.

Power Generation
Measuring radial vibration of steam turbine bearings to prevent high-speed rotating shafts from damaging bearing pads due to unbalance or misalignment.

Oil & Gas
Applied in axial displacement monitoring of water injection pumps to strictly prevent pump shafts from colliding due to excessive axial thrust.

Petrochemical Industry
Installing the probe on an ethylene centrifugal compressor to provide Keyphasor phase reference signals for shaft speed and phase analysis.

Air Separation Industry
Monitoring the axial float of air separation compressors to prevent direct rubbing between the rotor and stator.

Nuclear Power Industry
Used for bearing condition monitoring of main feedwater pumps in nuclear power plants, serving as a signal source for train interlock trip protection.

Paper & Pulp Industry
Used for measuring the vibration and alignment status of high-speed press roll drive shafts in paper machines.

 When using the 330102-00-31-05-02-00, the following critical points must be observed. Because this probe only comes with an attached 0.5-meter short cable, it cannot be connected directly to a Proximitor sensor on-site. It must be paired with a 4.5-meter or 8.5-meter 3300 XL extension cable to form a complete 5-meter or 9-meter measurement loop. Cutting, splicing, or utilizing an incorrect length of extension cable on-site is strictly prohibited as it will alter the system impedance and permanently invalidate the calibration. During routing, the minimum bend radius limit of 25.4 mm must be strictly respected to prevent damage to the internal coaxial structure, and the integrated stainless steel armor should be fully utilized for physical crush protection. Additionally, as the probe is factory-calibrated against AISI 4140 steel, the monitoring system scale factor must be adjusted if the target shaft is made of stainless steel or other alloys. When adjusting the installation depth, ensure the initial circuit gap voltage is stabilized near the linear midpoint of approximately -10 VDC.

Technical notes

In terms of specific hardware specifications, this model has a 3/8-24 UNF imperial threaded case with an unthreaded length of 0 mm and an overall case length of 3.1 inches. It includes an attached 0.5-meter standard cable covered by an AISI 302 stainless steel flexible armored conduit and a miniature coaxial ClickLoc connector. Because this specific unit utilizes an integrated short cable, it requires a separate 3300 XL extension cable in field routing to establish a complete signal transmission path to the Proximitor sensor. For practical application and routine maintenance on-site, this hardware setup functions in exceptionally tight installation spaces where larger pre-assembled components cannot be placed.

FAQ View All FAQ

  • What is the 330102-00-31-05-02-00 device?
    It is a Bently Nevada 3300 XL 8 mm eddy current proximity transducer probe, which belongs to industrial-grade non-contact bearing condition monitoring sensors.
  • What is the primary operating principle of the 330102-00-31-05-02-00?
    It operates by emitting a high-frequency electromagnetic field from the probe tip to generate eddy currents on the observed metal shaft surface. The resulting energy loss varies with the distance between the probe tip and the metal surface.
  • How do you use products like the 330102-00-31-05-02-00?
    It cannot work alone; it must be rigidly mounted on the machine bearing housing, connected to a 3300 XL Proximitor Sensor via a 3300 XL extension cable, and then feed signals into monitoring instruments or protection systems.
  • What industrial machinery is the 330102-00-31-05-02-00 primarily applied to?
    It is primarily applied to large rotating machinery utilizing fluid-film bearings, such as steam turbines, centrifugal compressors, large water pumps, fans, and generators.
  • What data can the 330102-00-31-05-02-00 measure?
    It can measure both static data (such as absolute shaft position and axial displacement) and dynamic data (such as radial shaft vibration and relative runout).
