Bently Nevada 330710-000-050-50-02-05 3300 XL 11 mm Proximity Probes

Product Introduction

The Bently Nevada 330710-000-050-50-02-05 3300 XL 11 mm Proximity Probe is a high-reliability non-contact vibration and shaft-position sensor engineered for critical rotating machinery. Part of the proven 3300 XL family, it provides precise displacement measurements by detecting changes in the eddy current field between the probe tip and the target surface. The probe is designed to meet rigorous API 670 standards and is widely used in power generation, oil & gas, and industrial process applications where continuous condition monitoring is essential.

Product Parameters

Applications

The 3300 XL 11 mm probe is deployed across a wide range of machinery monitoring scenarios:

• Turbomachinery – Continuous vibration and axial displacement monitoring on steam, gas, and hydro turbines.

• Compressors & Pumps – Shaft vibration and thrust position measurement for critical compressor and pump trains.

• Generators & Motors – Rotor position tracking to prevent rubs or bearing damage.

• Industrial Fans & Blowers – Condition monitoring to detect imbalance or misalignment before failure occurs.

• Gearboxes – Early detection of gear mesh issues through casing vibration measurements.

Advantages

• API 670 Compliance – Meets global industry standards for machinery protection systems.

• Exceptional Stability – Low thermal drift and wide operating temperature range ensure reliable data in harsh environments.

• Rugged Design – Stainless-steel probe body and armored cable provide mechanical durability and corrosion resistance.

• High Accuracy – Consistent sensitivity and linearity deliver precise displacement data for advanced diagnostics.

• Ease of Integration – Compatible with Bently Nevada 3300 and 3500 monitoring systems for seamless upgrades.

• Reduced Maintenance – Non-contact sensing eliminates physical wear and minimizes downtime.

FAQ

1. What type of target material provides the most accurate calibration?
   AISI 4140 or similar carbon steel is recommended for factory calibration and best accuracy.

2. How is the probe electrically shielded to reduce noise?
   The probe uses a coaxial design with integral shielding and grounded armor to minimize electromagnetic interference.

3. Can the probe operate reliably in high-vibration environments?
   Yes, it is designed to withstand severe vibration without affecting measurement fidelity.

4. What is the typical output impedance of the probe system?
   Approximately 50 Ω when connected with the matching extension cable and driver.

5. How does the probe compensate for temperature variations?
   Factory compensation materials and circuitry provide minimal thermal drift across the full operating range.

6. Is the probe compatible with older Bently Nevada 7200 series drivers?
   It is recommended to pair the 3300 XL probe with 3300 or 3500 drivers for full specifications, though backward compatibility may be possible with calibration.

7. What is the recommended gap voltage for optimal linearity?
   Typically –10 VDC at the mid-gap position is specified for best linear output.

8. How does cable length affect signal quality?
   The probe is factory-calibrated for a total system length; using non-standard lengths requires recalibration to maintain accuracy.

9. What protection is provided against moisture ingress?
   The probe assembly meets IP67 sealing requirements when installed with proper hardware.

10. What is the maximum static pressure rating of the probe tip?
    It is rated up to 2000 psi (137 bar), suitable for most industrial applications.
