FAQ

1. What is the nominal sensitivity of the 330192-00-70-05-CN probe?

   The probe is factory-calibrated to deliver a nominal sensitivity of about 7.87 mV/µm (200 mV/mil), ensuring accurate vibration and shaft-displacement measurements across its entire linear range.

2. Which monitoring systems can this probe be integrated with?

   It is fully compatible with Bently Nevada 3300 XL Proximitor® sensors and approved extension cables, allowing seamless integration into standard Bently Nevada vibration and position monitoring systems without special adapters.

3. What operating temperature range does the probe body support?

   The probe itself functions reliably from –35 °C to +200 °C, while its armored cable and connector assembly operate from –51 °C to +177 °C, enabling dependable performance in extreme hot or cold environments.

4. How is the probe mechanically installed on equipment?

   Installation is achieved through an M10 × 1 mm threaded connection secured with a locknut. This design allows quick field mounting and ensures the probe remains tightly fixed under continuous vibration.

5. What measurement technology does the probe utilize?

   The device uses eddy-current displacement sensing, a non-contact technology that measures the distance between the probe tip and the rotating shaft to provide real-time vibration and position data.

6. What continuous vibration levels can the probe withstand?

   It is rated for continuous operation at up to 20 g in the 10–2000 Hz frequency range, which covers the vibration spectrum of most industrial rotating machinery.

7. Does the probe have environmental sealing for harsh conditions?

   Yes, the probe assembly meets the IP67 standard, offering complete dust tightness and protection against water immersion, making it suitable for outdoor or wash-down areas.

8. What is the maximum mechanical shock rating?

   The probe is tested to withstand shocks up to 200 g peak, ensuring durability during sudden equipment starts, stops, or accidental impacts.

9. Is the cable supplied and how is it configured?

   Each unit includes a 0.5 meter armored, factory-terminated cable that is pre-assembled to maintain signal integrity and minimize installation time in the field.

10. Can the probe measure both radial and axial shaft motion?

    Yes. The design supports dual functionality, allowing it to monitor radial shaft vibration as well as axial position changes, which is essential for comprehensive turbomachinery diagnostics.
