Eddy-Current Probe Scaling and Rotor Dynamics Measurement

The 330104-00-10-10-02-CN uses an eddy-current sensing circuit to convert shaft displacement into proportional electrical signals. The probe works with compatible Proximitor sensors to provide a calibrated output scale of 7.87 V/mm (200 mV/mil). Therefore, the system can evaluate dynamic vibration movement and static shaft position without physical contact.

Additionally, the 3300 XL 8 mm system supports rotor dynamics analysis by maintaining consistent probe interchangeability among compatible probes, extension cables, and signal conditioners. The installation requires correct gap voltage adjustment to maintain measurement accuracy, and Bently Nevada systems commonly validate probe operation around the -10 VDC gap voltage target.

Frequently Asked Questions

Q: Does the 330104-00-10-10-02-CN require individual bench calibration before replacement installation?
A: No. The 3300 XL 8 mm proximity probe supports interchangeability with compatible extension cables and Proximitor sensors when the complete system configuration matches the specified requirements.

Q: What measurement principle does this proximity probe use?
A: The probe uses an eddy-current measurement principle. It generates an electromagnetic field and detects changes caused by the distance variation between the probe tip and the conductive shaft surface.

Q: Can this probe measure both vibration and shaft position?
A: Yes. The probe measures both dynamic displacement changes for vibration monitoring and static displacement changes for shaft position monitoring.

Field Installation Guidelines

• Install the probe with the specified M10 x 1 mounting thread and maintain mechanical alignment with the rotating target surface.
• Verify that the probe tip faces the conductive shaft material within the specified linear measurement range.
• Maintain proper cable routing to reduce mechanical stress and avoid sharp bending near the ClickLoc connector.
• Connect the cable shield according to the monitoring system grounding requirements to minimize electrical interference.
• Confirm the probe gap voltage after installation. Bently Nevada proximity systems typically use a -10 VDC gap voltage target for standard operating adjustment.
• Avoid installation locations with excessive contamination, direct impact, or mechanical damage risk to the probe tip and cable assembly.
