Eddy-Current Signal Scaling and Rotor Dynamics Interface
The 330130-085-02-05 extension cable forms part of the Bently Nevada 3300 XL 8mm Proximity Transducer System, which uses eddy-current probe scaling to convert shaft displacement into proportional output voltage. The cable maintains signal integrity between the probe and Proximitor Sensor, allowing measurement of both static shaft position and dynamic vibration signals.
Furthermore, the extension cable supports rotor dynamics monitoring applications by maintaining the electrical characteristics required for fluid-film bearing machine measurements. The complete system provides stable proximity signal transmission for vibration analysis, Keyphasor reference detection, and rotational speed measurement.
The 3300 XL system configuration supports gap voltage validation using standard -10 VDC target values for probe operating condition verification. Additionally, the cable design provides interchangeability between compatible probes, extension cables, and Proximitor Sensors without individual component bench calibration.
Frequently Asked Questions
Q: What function does the 330130-085-02-05 extension cable perform in the 3300 XL system?
A: The cable extends the electrical connection between the 3300 XL 8mm proximity probe and the Proximitor Sensor while maintaining the required signal characteristics.
Q: Is the 330130-085-02-05 cable compatible with vibration and position measurement applications?
A: Yes. The cable supports the 3300 XL 8mm proximity system used for shaft vibration, shaft position, Keyphasor reference, and speed measurement signals.
Q: Does the extension cable require external power or configuration settings?
A: No. The extension cable is a passive component and does not require external power or firmware configuration.
Field Installation Guidelines
- Install the 330130-085-02-05 cable according to the 3300 XL proximity transducer system wiring requirements.
- Maintain separation between proximity signal cables and high-current power conductors to reduce electrical interference.
- Connect cable shielding according to site grounding practices and avoid multiple ground paths that may introduce noise.
- Confirm connector engagement and mechanical protection before equipment startup.
- Verify the complete probe, extension cable, and Proximitor Sensor combination before commissioning.
- Check the probe gap voltage during installation and confirm the expected operating range before machinery operation.
