SKU: 330103-00-11-10-02-00
Bently Nevada 3300 XL 11 mm Proximity Probe 330103-00-11-10-02-00
The Bently Nevada 330103-00-11-10-02-00 is a 3300 XL 11 mm proximity transducer featuring an M14x1.5 metric thread and a 1.0-meter cable. This high-precision sensor delivers an extended 4.0 mm linear range, making it the ideal solution for monitoring axial position and vibration in large-scale turbines and compressors.
Technical Operational Overview
The Bently Nevada 330103-00-11-10-02-00 functions as a high-performance eddy current sensor within the 3300 XL series. Engineers specifically developed this 11 mm proximity transducer to provide a wider linear range than standard 8 mm models, making it ideal for applications where greater displacement measurements are necessary. By generating a high-frequency magnetic field, the probe captures minute changes in the gap between the sensor tip and the target shaft. Consequently, the system translates these physical movements into precise electronic signals, allowing the 3500 monitoring system to track machinery health with exceptional resolution.

Core Applications in Heavy Industry
Because the 11 mm probe offers an extended linear range, it excels in monitoring large-scale rotating equipment where axial float or thermal expansion might exceed the limits of smaller sensors. Facilities typically deploy these transducers on massive steam turbines, large centrifugal compressors, and heavy-duty gearboxes. Furthermore, the 330103 series provides essential data for:
- Radial vibration monitoring in oversized fluid-film bearings
- Axial (thrust) position tracking to prevent catastrophic rotor-to-stator contact
- Differential expansion measurements in large power generation turbines
- High-accuracy speed sensing and Keyphasor applications for phase reference
Reliability and System Integration
The 3300 XL 11 mm system demonstrates superior resistance to “crosstalk” and electromagnetic interference, ensuring signal purity even in dense industrial wiring environments. Additionally, the probe utilizes a specialized TipLoc molding process that bonds the probe tip to the body, which prevents fluid leakage and maintains vacuum seals. This robust construction allows the sensor to thrive in environments saturated with hot oil, steam, or corrosive gasses. By integrating this transducer into a proactive maintenance framework, operators can effectively eliminate unexpected outages and prolong the operational life of their most valuable rotating assets.
