Bently Nevada 330704-00-050-10-01-05 3300 XL 11 mm Proximity Probes

Product Introduction

The Bently Nevada 330704-00-050-10-01-05 3300 XL 11 mm Proximity Probe is a high-precision, non-contact displacement sensor designed for continuous monitoring of shaft vibration and rotor position in critical rotating machinery. As part of the renowned 3300 XL series, it combines advanced eddy-current sensing technology with a rugged mechanical design to deliver exceptional measurement accuracy, linearity, and stability in harsh industrial environments. Its stainless-steel construction and robust insulation ensure long-term reliability in power generation, oil and gas, and heavy process industries. Seamless integration with Bently Nevada 3300 XL Proximitor® sensors allows predictive maintenance systems to detect early signs of imbalance, misalignment, or bearing wear, thereby preventing costly downtime.

Frequently Asked Questions (FAQ)

1. What measurement principle does this probe use?
   It uses eddy-current sensing to measure shaft displacement without physical contact.

2. How is linearity maintained over the 11 mm range?
   Internal calibration and temperature-compensated materials ensure stable, linear output.

3. Is it compatible with Bently Nevada 3300 XL Proximitor®?
   Yes, it connects directly for precise displacement signals.

4. How does it resist electromagnetic interference (EMI)?
   Shielded housing and proper grounding reduce susceptibility to electrical noise.

5. Can it capture fast vibration transients?
   Yes, its frequency response up to 10 kHz allows detection of rapid shaft movements.

6. What are the mounting requirements?
   Mount on a rigid, flat surface with correct alignment and the recommended probe gap.

7. Which shaft materials are supported?
   Conductive ferromagnetic shafts are ideal; non-conductive coatings should be avoided.

8. How does temperature variation affect the probe?
   Low-expansion materials and internal compensation minimize temperature-induced errors.

9. What maintenance is recommended?
   Check connectors, verify signal, and inspect probe alignment periodically.

10. How does the probe handle mechanical vibration and shock?
    Robust stainless steel housing and ceramic tip withstand high vibration and shocks.
