Frequently Asked Questions (FAQ)

1. What sensing principle does this probe use?
   It operates on an eddy-current principle to measure the gap between the probe tip and the shaft surface.

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

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

4. Does the probe require recalibration after installation?
   Only basic system verification is typically required; no field recalibration is necessary.

5. How does it perform under high vibration levels?
   It withstands up to 20 g across the 10–2000 Hz range without signal degradation.

6. What target material ensures best measurement accuracy?
   Conductive ferromagnetic materials such as steel provide optimal results.

7. Is it suitable for continuous 24/7 monitoring?
   Yes, it is designed for permanent installation in critical machinery requiring constant surveillance.

8. What is the frequency response range?
   The probe delivers accurate data from DC up to 10 kHz, ideal for dynamic vibration measurement.

9. Can the probe detect both radial and axial displacement?
   Yes, depending on installation orientation it can measure either radial or axial shaft movement.

10. How is electromagnetic interference minimized?
    Multi-layer shielding and precision grounding techniques reduce EMI for stable signal output.
