The Bently Nevada 330103-00-05-20-02-CN is a high-precision 8 mm proximity probe from the trusted 3300 XL series, engineered for non-contact measurement of shaft vibration, displacement, and position in critical rotating equipment. It is widely recognized for its stability, long-term reliability, and rugged construction in harsh industrial environments.

This specific model is configured with a 5-meter integral cable, 5/8-18 UNF mounting thread, and a 90° angled connector. The “-CN” suffix denotes a China-specific connector or certification, optimized for localized equipment and installations. Designed for use with 3300 XL extension cables and Proximitor sensors, this proximity probe ensures accurate and repeatable measurements, even in high-vibration and high-temperature conditions.

Frequently Asked Questions (FAQ)

1. What does the “-CN” in the model number indicate?

   It refers to a connector style and certification tailored for the Chinese market or GB compliance.

2. Is the probe compatible with non-CN Bently Nevada systems?

   Yes, functionally it is fully compatible with all 3300 XL system components.

3. What is the purpose of the 90° connector?

   It allows installation in restricted spaces where straight connectors would not fit.

4. What is the minimum distance from the shaft for correct sensing?

   The recommended gap is typically 1 mm (40 mils), depending on calibration.

5. Can this be used in high-vibration environments like turbines?

   Absolutely—it withstands up to 50 g vibration and 5000 g shock.

6. Does the probe require recalibration over time?

   No, factory calibration is stable, but periodic system checks are advised.

7. What is the lifespan of the probe?

   Designed for 7–10 years of service under normal industrial conditions.

8. Is the cable shielded?

   Yes, the triaxial design provides excellent noise immunity.

9. Does the CN version support standard BNC extension cables?

   Only if matched with corresponding CN-compatible cables or adaptors.

10. How should the probe be mounted?

    Secure using the threaded body; avoid over-tightening and ensure correct axial alignment.
