Eddy-Current Probe Scaling
The probe is calibrated for –10 VDC gap voltage validation, ensuring accurate displacement conversion. Its 50‑ohm output impedance supports stable signal transmission to Proximitor sensors. Cross-talk suppression within the coaxial system maintains fidelity when multiple probes are installed in close proximity, enabling precise rotor dynamics monitoring.
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: What connector type is used? A: A miniature coaxial ClickLoc connector with standard cable is provided.

Field Installation Guidelines
Install 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.
