Frequently Asked Questions (FAQ)

1. Is this probe compatible with the 3300 XL Proximitor Sensor?

   Yes, it is specifically designed to be used with the 3300 XL Proximitor Sensor and matching extension cables.

2. Can the cable length be modified in the field?

   No, the cable length is factory-set and matched to the Proximitor sensor. Field modification will compromise system accuracy.

3. What is the expected output voltage at the mid-gap position?

   The mid-gap voltage is typically around -10 VDC, depending on installation and calibration.

4. What kind of shaft material is best for calibration?

   4140 steel is the standard material used during calibration. Deviations may require recalibration.

5. Is it suitable for hazardous area installations?

   Yes, with the appropriate intrinsic safety barriers and certified installation practices.

6. How do I test if the probe is still functioning properly?

   Use a Bently signal checker or diagnostic software in combination with a dial micrometer for accuracy verification.

7. Can this be used for axial thrust monitoring?

   Yes, when correctly installed and configured with a matching proximitor module.

8. What is the probe’s lifespan under continuous use?

   Probes typically last for years under normal operation. However, extreme environments may reduce service life.

9. Does this probe support condition monitoring and protection systems?

   Absolutely. It integrates seamlessly into Bently Nevada’s 3500 series monitoring systems.

10. What happens if I exceed the vibration/shock limit?

    Exceeding limits can permanently damage the probe or degrade its accuracy. Always install according to specifications.
