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 -52 to +177 deg C operating range.
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 nominal scale factor of the probe? A: The probe provides a nominal scale factor of 7.87 V/mm (200 mV/mil) when paired with matching proximitor sensors.
Q: How does the probe maintain signal integrity in multi‑channel systems? A: Cross‑talk suppression is achieved through coaxial shielding and precise impedance matching in the ClickLoc connector design.
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.
Verify O‑ring seal integrity to maintain pressure resistance.
Confirm driver calibration after installation to ensure proper sensitivity scaling.
