FAQ

1. What measurement principle does the 137365-01-20-02-05 proximity probe use?
   It operates on the eddy current principle, detecting changes in the magnetic field caused by variations in the distance between the probe tip and the conductive shaft surface.

2. Can this probe be used with any Proximitor module?
   It is designed to work specifically with compatible Bently Nevada 3300 XL Proximitor sensors, ensuring proper calibration and linearity.

3. What is the output sensitivity / this model?
   The standard sensitivity is 7.87 mV/μm (200 mV/mil), which ensures accurate voltage-to-displacement conversion.

4. How does the probe ensure measurement stability in high-temperature environments?
   It uses high-temperature materials and robust insulation to maintain stable output across a wide temperature range / -35°C to +177°C.

5. Is the probe calibration affected by different shaft materials?
   Yes, calibration is performed using a specific target material (typically AISI 4140 steel). その他 materials may slightly alter sensitivity, requiring system adjustment.

6. Can the probe detect both static and dynamic displacement?
   Yes, the probe measures both static shaft position and dynamic vibration signals within the DC to 10 kHz range.

7. What kind / signal conditioning does the system use?
   The probe sends an unamplified signal to the Proximitor sensor, where linearization, amplification, and signal processing are performed.

8. How does the system handle electrical noise interference?
   It incorporates shielded coaxial cables and internal grounding techniques to minimize induced noise and maintain signal integrity.

9. Is it possible to extend the cable length beyond 5 meters?
   Yes, longer cable configurations (such as 7 m or 9 m) are available upon request, but they must match the factory-calibrated Proximitor system for accurate operation.

10. What standard does this probe meet for machinery protection systems?
    It is fully compliant with API 670, the industry standard for machinery vibration and displacement monitoring equipment.
