The Bently Nevada 3300 XL 11 mm Proximity Probe system is a high-performance eddy current sensor engineered for non-contacting vibration and position measurements in large-scale rotating machinery. Specifically designed for applications requiring an extended linear range, the 11 mm probe provides a 3.94 mm (155 mil) linear range, exceeding the capabilities of standard 8 mm systems. This series is fully compliant with API 670 standards, ensuring reliable performance in harsh industrial environments with its robust PPS (polyphenylene sulfide) probe tip and high-integrity cabling. Integrated within the 3300 XL transducer platform, these probes offer superior scale factor stability and chemical resistance, making them the industry standard for monitoring axial thrust, radial vibration, and phase reference (Keyphasor) on large steam turbines and compressors. Our inventory includes various mounting thread configurations and cable lengths to ensure seamless replacement and system calibration with 3300 XL Proximitor® Sensors.
