Eddy-Current Probe Scaling
The 3300 XL 8 mm probe family is engineered for:
Gap voltage validation at -10 VDC reference targets.
Rotor dynamics monitoring with stable linearity across 0.25–2.3 mm.
Cross‑talk suppression in multi‑channel installations.
Thermal stability maintained across extended operating ranges.
Frequently Asked Questions (FAQ)
Q: Can the probe be hot‑swapped during operation? A: No. Removal or insertion must be performed with the monitoring system powered down to maintain calibration integrity.
Q: What is the typical linear range of this probe? A: The probe provides a 2.0 mm (80 mils) linear range when paired with matching proximitor sensors.
Q: How does the connector design affect installation? A: The miniature coaxial ClickLoc connector ensures secure coupling and impedance stability, reducing signal loss in high‑vibration environments.
Field Installation Guidelines
Install probe tip perpendicular to shaft surface for accurate displacement readings.
Maintain insertion depth to align with -10 VDC gap reference calibration.
Route 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 sensitivity scaling.
Ensure probe case clearance in confined turbine applications.
