3300 XL 8 mm Proximity Probe | 330103-00-06-05-02-02 | Bently Nevada

Technical Specifications

The 3300 XL 8 mm Proximity Transducer 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. 

Advantages of Installing the 0.5-meter Probe

Concealed Installation Inside the Housing: This probe is typically designed for applications where cables must exit the bearing housing "nearby." The mere 0.5-meter cable occupies minimal space within the unit's bearing housing, effectively avoiding the physical risks of excessively long cables being caught or scratched by high-speed splashing lubricating oil, rotating shafts, or gears inside the unit.

Highly Flexible External Wiring: After exiting the housing, the cable is immediately converted into a longer, robust extension cable via its included -02 connector protector for long-distance routing. This "extremely short internal, extended external" design greatly facilitates the rapid disassembly and partial replacement of sensor hardware during unit overhauls.

Shielding to Ground Isolation (Protection Against Ground Loop Current)

Although this probe is non-armored, the -02 plastic protector must be fully tightened when connecting the 0.5-meter cable to the extension cable. Contact between the coaxial connector housing and the unit metal body is prohibited. The system shielding layer should be grounded only at the safe-zone instrument panel end (such as the 3500 frame or DCS grounding grid). Secondary grounding on the probe side may create ground loop currents, introducing 50Hz noise into the vibration signal and causing false trips.

Technical FAQ

Q: What specifications are used in the mechanical housing design of the model?

A: The prefix 330103 indicates a Bently Nevada 3300 XL series 8 mm reverse mount eddy current probe. It uses an M10 × 1 metric threaded housing; suffix 00 indicates a 0 mm threadless length, and 06 indicates a 60 mm overall case length.

Q: If I need to configure the model 330103-00-06-05-02-02 in a standard 5-meter overall measurement system, how should I select an extension cable?

A: Since this probe includes a 0.5-meter (0.5 m) cable, a 3300 XL extension cable with a precise length of 4.5 meters must be selected to achieve the standard 5-meter system length and impedance matching.

Q: What configurations are provided for the cable termination and materials of model 330103-00-06-05-02-02 when dealing with severe industrial high-frequency mechanical vibrations?

A: The first "02" in the suffix indicates that a Miniature ClickLoc coaxial connector with mechanical locking is used, and standard high-performance fluorinated ethylene propylene (FEP) insulation is applied to the cable without additional armor or protective sheath.

Q: How does the model 330103-00-06-05-02-02 perform in terms of non-contact electrical measurement and industrial environment tolerance?

A: It provides a precise 2.0 mm (80 mils) nominal linear measurement range and a standard output sensitivity of 200 mV/mil. Its probe tip is made of high-strength polyphenylene sulfide (PPS), and the housing is made of stainless steel. It can work stably for a long time in a wide temperature range of -52 °C to +177 °C.
