Product Introduction

The Bently Nevada 330105-02-12-02-05-00 3300 XL 8mm Reverse Mount Probe is a high-performance non-contact sensor designed for precise vibration and position measurement in rotating machinery. As part of the 3300 XL series, this probe represents the industry standard for reliability and accuracy in proximity sensing applications. Unlike standard forward-mount probes, the reverse mount configuration allows installation from the back of the mounting bracket or machine housing, which is ideal for confined or high-vibration areas.

This probe operates based on eddy current technology, providing accurate, stable measurements of the distance between the probe tip and a conductive target surface, typically a rotating shaft. The 330105-02-12-02-05-00 is engineered to deliver consistent performance in demanding industrial environments such as power generation, oil & gas, and heavy manufacturing. Its design ensures long-term stability and immunity to electromagnetic interference and contamination.

FAQ

1. What is the primary difference between the reverse mount and forward mount probe configurations?
   The reverse mount probe installs from the rear of the mounting location, making it ideal for applications with limited front access or higher vibration levels, while maintaining identical sensing characteristics to forward mount probes.

2. How does the 330105-02-12-02-05-00 detect shaft vibration?
   It uses eddy current sensing to detect variations in the electromagnetic field between the probe tip and the conductive target, translating these variations into voltage signals proportional to displacement.

3. Can this probe be used with other Bently Nevada extension cables?
   Yes, it is fully compatible with 3300 XL extension cables, ensuring accurate calibration when used as part of the complete system.

4. What type of material is recommended for the target surface?
   The probe is designed for conductive materials, typically steel, and is calibrated specifically for AISI 4140 steel targets for best accuracy.

5. How does the probe maintain accuracy in contaminated environments?
   The probe’s stainless steel body and sealed design prevent oil and dust ingress, maintaining measurement accuracy even in challenging environments.

6. Does temperature variation affect probe output?
   The system compensates for temperature changes with less than ±5% signal deviation across its full operating range.

7. Can the probe withstand high mechanical vibrations?
   Yes. It is rated for continuous vibration exposure up to 20 g peak and short-duration shocks up to 500 g, ensuring reliable operation in rotating machinery.

8. How should the gap between the probe and target be adjusted?
   The gap should be set according to the manufacturer’s specified target distance (typically around 1.0 mm), verified using the Proximitor calibration output.

9. Is the probe electrically isolated from the machine frame?
   Yes, it is internally isolated, eliminating ground loops and minimizing electrical interference in the monitoring system.

10. Can the probe be integrated into a Bently Nevada 3500 system?
    Absolutely. It is fully compatible with the 3500 Monitoring System, providing precise displacement and vibration inputs for advanced condition monitoring.
