Eddy-Current Probe Scaling and Rotor Dynamics Monitoring

The 330104-00-22-10-01-05 uses eddy-current sensing technology to convert shaft displacement into proportional electrical signals. The probe provides a scale factor of 7.87 V/mm for dynamic vibration and static position measurements.

Furthermore, the system requires gap voltage validation during commissioning to confirm the probe operating point. Bently Nevada proximity systems typically use approximately -10 VDC gap voltage targets to verify correct probe-to-shaft positioning.

The probe supports rotor dynamics analysis by measuring radial vibration, axial shaft position, speed references, and Keyphasor related signals. Therefore, engineers can evaluate shaft movement behavior through compatible TSI monitoring modules.

The armored cable construction reduces mechanical damage risks in industrial installations. Additionally, the miniature coaxial ClickLoc connector maintains signal continuity between the probe and the associated Proximitor sensor.

Frequently Asked Questions

Q: What measurement principle does the 330104-00-22-10-01-05 use?
