Eddy-Current Probe Scaling
The probe is calibrated for–10 VDC gap voltage validation, ensuring accurate conversion of shaft displacement into electrical signals. This scaling supports rotor dynamics analysis and vibration monitoring. The patented TipLoc and CableLoc designs enhance mechanical robustness, preventing probe tip movement and ensuring secure cable retention under industrial vibration conditions.
Frequently Asked Questions
Q: What is the linear operating range of the probe? A: The probe supports a 2 mm (80 mils) linear range.
Q: How does the probe maintain mechanical integrity? A: TipLoc molding secures the probe tip, while CableLoc attachment prevents cable pull-out.
Q: What is the maximum operating temperature? A: The probe is rated for –52 °C to +218 °C (–62 °F to +424 °F).
Field Installation Guidelines
Position probe tip perpendicular to shaft surface for accurate displacement measurement.
Adjust insertion depth to achieve –10 VDC gap reference.
Route coaxial cable with shielding grounded at a single point to minimize interference.
Avoid sharp bends in cable to prevent conductor fatigue.
Confirm driver calibration after installation to ensure proper scaling.
