Frequently Asked Questions (FAQ)

1. What is the purpose of the 330101-00-45-05-02-00 probe?

   It measures the proximity (distance) between the probe tip and a conductive shaft to monitor vibration and position in rotating machinery.

2. Can this probe be used in high-temperature environments?

   Yes, it supports operation up to +177°C, making it suitable for many high-temperature industrial applications.

3. Does it require a matching proximitor and extension cable?

   Yes, this probe is part of a three-component system and must be paired with specific 3300 XL cables and Proximitor sensors.

4. Is this model suitable for forward mounting only?

   Correct, this variant uses a forward mount configuration and is threaded for installation from the machine exterior.

5. What materials can it sense?

   Standard calibration is for AISI 4140 steel, but custom calibrations are possible for other conductive targets.

6. Is the cable replaceable or field-repairable?

   No, the probe cable is fixed. If damaged, the entire probe needs replacement.

7. Can the system detect bearing failures?

   Indirectly, yes—by measuring shaft vibration, it can identify signs of bearing wear or failure.

8. What’s the minimum measurable distance?

   The linear operating range begins at 0.5 mm from the target surface.

9. Is it compatible with older Bently Nevada systems?

   It is optimized for the 3300 XL system and may not be compatible with legacy systems like the 7200 series.

10. How do I ensure proper sealing for IP65 protection?

    Use approved gaskets, sealing compounds, and proper cable glands as per Bently Nevada’s installation guidelines.
