Bently Nevada 330703-000-070-10-02-00 3300 XL 11 mm Proximity Probe

Product Overview

The Bently Nevada 330703-000-070-10-02-00 is the sensing element of the 3300 XL 11 mm Proximity Transducer System, designed for non-contact measurement of shaft displacement using eddy current technology. It monitors radial vibration and axial position in turbomachinery such as steam turbines, compressors, and large rotating equipment. The probe delivers high-resolution, real-time displacement data essential for machinery protection, performance monitoring, and condition-based maintenance systems.

Engineering Advantages

  • Extended Linear Range for Large Machinery
    The 11 mm probe provides a 4.0 mm linear range, allowing accurate measurement of larger shaft excursions caused by thermal growth and dynamic loads in heavy turbomachinery.

  • Moisture and Contamination Protection
    The integrated connector protector (02 option) shields the coaxial interface from oil, moisture, and contaminants, improving signal stability and reducing false readings.

  • High Chemical and Thermal Resistance
    The PPS tip material maintains structural integrity and calibration stability under aggressive chemicals, lubricants, and elevated temperatures.

  • Vibration-Resistant Connector Interface
    The ClickLoc gold-plated connector ensures a secure mechanical and electrical connection, minimizing signal interruptions in high-vibration environments.

  • Optimized Installation Geometry
    The 70 mm case length allows proper penetration through machine housings while positioning the connector outside high-temperature zones, improving serviceability and reliability.

FAQs

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

Can this probe be used with an 8 mm Proximitor?
No, it must be paired with a compatible 11 mm Proximitor. Mixing probe sizes leads to incorrect scaling and unreliable measurements.

What is the function of the connector protector?
The protector seals the connector interface against moisture, oil, and contaminants, helping prevent signal instability and ensuring long-term reliability.

Does cable length affect calibration?
Yes, the total system length (probe cable plus extension cable) must match the Proximitor’s calibration (typically 5 m or 9 m systems) to ensure accurate output.
