Eddy-Current Signal Scaling and Rotor Dynamics Monitoring

The 330104-00-13-05-02-00 probe uses eddy-current technology to convert shaft displacement into electrical signals. Therefore, the connected 3300 XL Proximitor Sensor can process gap distance variations for vibration and position analysis.

The probe system uses a defined scale factor of 7.87 V/mm, which allows the monitoring system to correlate voltage changes with mechanical shaft movement. In addition, proper gap voltage validation supports installation verification, with Bently Nevada systems typically using -10 VDC target gap settings for measurement calibration.

Furthermore, the probe supports rotor dynamics analysis by providing continuous shaft vibration and axial position data. The miniature coaxial ClickLoc connector design maintains signal integrity while reducing installation complexity in TSI monitoring applications.

Frequently Asked Questions

Q: What measurement signals does the 330104-00-13-05-02-00 provide?
A: The probe provides non-contact displacement signals for radial shaft vibration, axial position, and rotational reference measurements when connected to a compatible 3300 XL Proximitor Sensor.

Q: Can the probe operate without a Proximitor Sensor?
A: No. The 330104 probe requires a compatible Bently Nevada Proximitor Sensor to generate and condition the eddy-current measurement signal.

Q: What installation factors affect measurement accuracy?
A: Installation accuracy depends on correct probe gap adjustment, proper thread engagement, target surface condition, cable routing, and correct shielding practices.

Field Installation Guidelines

1. Install the probe with the specified M10 x 1 mounting thread and maintain mechanical alignment with the monitored shaft surface.
2. Verify the probe gap voltage after installation using the connected Proximitor Sensor. Confirm that the measured gap remains within the expected operating range.
3. Route the coaxial cable away from high-current power conductors, switching devices, and electromagnetic interference sources.
4. Maintain proper cable shielding and grounding practices according to the vibration monitoring system installation requirements.
5. Inspect the probe tip and shaft target surface before commissioning. Remove contamination, excessive oxidation, or mechanical damage that may affect eddy-current signal stability.
