Product Overview

The Bently Nevada 330101-00-79-10-02-05 is a high-performance 8mm eddy current proximity probe designed for precision shaft displacement monitoring. As a core sensing element of the 3300 XL Proximity Transducer System, this probe provides non-contacting measurements of vibration and axial position on critical rotating machinery. It operates by translating the physical gap between the sensor tip and a conductive target into a precise electrical signal, enabling real-time diagnostics of machine health.

This specific configuration is engineered for reliability in Turbine Supervisory Instrumentation (TSI) applications. It is particularly effective for monitoring fluid-film bearing machines, providing critical data for radial vibration analysis, axial thrust tracking, and Keyphasor phase reference measurements. Its robust design ensures it can withstand the volatile temperatures and mechanical stresses common in power generation and heavy industrial environments.

Key Technical Characteristics

• API 670 Standard Compliance: Fully adheres to the industry standards for mechanical configuration, linear range, and thermal stability, ensuring high-fidelity data for machinery protection systems.

• Universal Component Match: Features the "universal match" architecture of the 3300 XL series, allowing probes, extension cables, and Proximitor sensors to be interchanged without the need for manual bench calibration.

• Superior Connection Security: Equipped with a ClickLoc miniature coaxial connector, providing a secure electrical junction that resists loosening under vibration while facilitating fast installation.

• Broad Temperature Range: Capable of operating in extreme industrial climates, with a rated performance envelope spanning from -51°C to +177°C.

• Backward Compatibility: Offers seamless integration with legacy non-XL 3300 series 5mm and 8mm transducer components, providing a cost-effective path for system upgrades.

• Optimized Mechanical Design: Features a 3/8-24 UNF thread profile (unarmored) for standard mounting, combined with a 1-meter lead cable for flexible routing to extension cable junctions.
