Frequently Asked Questions (FAQ)

1. What sensing technology does this probe utilize?
   It uses an eddy-current principle to measure the distance between the probe tip and the rotating shaft.

2. Is it pre-calibrated for the 3300 XL Proximitor®?
   Yes, it is factory-calibrated for direct connection to 3300 XL Proximitor® sensors.

3. What is the nominal output sensitivity?
   The probe provides approximately 5 mV/µm sensitivity for accurate displacement monitoring.

4. Can this probe handle continuous 24/7 monitoring?
   Yes, it is designed for permanent installation in critical machinery requiring constant surveillance.

5. How does it ensure immunity to electromagnetic interference?
   Multi-layer shielding and precision grounding minimize EMI for clean signal output.

6. What is the recommended target material for best accuracy?
   Conductive ferromagnetic materials, such as steel, ensure optimal measurement precision.

7. Does the probe require field calibration after installation?
   No, only a basic system verification is typically needed after installation.

8. What is the effective frequency response range?
   It provides accurate readings from DC to 10 kHz, suitable for dynamic vibration measurement.

9. Can it measure both radial and axial displacement?
   Yes, the installation orientation determines whether radial or axial shaft movement is captured.

10. How does it perform in high-vibration conditions?
    It withstands up to 20 g vibration within the 10–2000 Hz range without performance degradation.
