Bently Nevada 330703-000-050-10-01-00 3300 XL 11 mm Proximity Probe

Product Overview

The Bently Nevada 330703-000-050-10-01-00 is part of the 3300 XL 11 mm Proximity Transducer System, designed for high-precision vibration and position monitoring of rotating machinery. Using eddy current technology, the probe measures the distance between the probe tip and the shaft surface, providing accurate displacement signals for critical turbomachinery applications such as steam turbines, compressors, and generators. It is widely used in condition monitoring and protection systems to detect abnormal vibration, shaft movement, and thrust conditions.

Engineering Advantages

  • Extended Measurement Range
    The 11 mm probe provides a wider linear measurement range, making it suitable for machines with larger shaft movements and thermal expansion.

  • High-Integrity ClickLoc Connector
    Gold-plated ClickLoc connectors ensure secure locking and corrosion resistance, maintaining signal stability in high-vibration environments.

  • Chemical and Thermal Resistance
    The PPS probe tip resists degradation from harsh lubricants, chemicals, and elevated temperatures commonly found in petrochemical and power generation systems.

  • Optimized for Fluid-Film Bearings
    Designed to accurately measure shaft dynamics in fluid-film bearing machines, enabling early detection of issues such as oil whirl and shaft instability.

  • Simple Calibration Process
    Calibration is achieved through mechanical gap adjustment, allowing straightforward setup without complex electronic tuning.

FAQs

Is this probe brand new and original?
Yes, it is supplied as 100% brand new, original Bently Nevada hardware in factory-sealed packaging.

Can this 11 mm probe be used with an 8 mm Proximitor?
No, it must be paired with a compatible 11 mm Proximitor sensor. Mixing sizes results in incorrect scaling and inaccurate readings.

What does the “10” cable length represent?
It indicates a 1.0-meter integral cable. The total system length must be matched with the appropriate extension cable to meet calibration requirements (commonly 5 m or 9 m systems).

Does the probe require external power?
The probe itself does not require direct power. It is powered via the Proximitor sensor, which typically uses a -24 VDC supply from the monitoring system.
