Product Overview

The Bently Nevada 330180-X1-CN (Modification 145004-82) is a high-precision eddy current proximity transducer system engineered for the continuous monitoring of rotating machinery. Operating as part of the 3300 XL 8 mm series, this system generates a linear voltage output that corresponds exactly to the distance between the probe tip and the target shaft. It is a critical component for Turbine Supervisory Instrumentation (TSI), capable of delivering simultaneous measurements for vibration, axial position, and rotational speed (Keyphasor).

This specific "CN" variant with MOD 1450004-82 is designed to meet the rigorous demands of API 670 standards, ensuring mechanical interchangeability and thermal stability across industrial applications. The system architecture—consisting of the proximity probe, extension cable, and Proximitor sensor—eliminates the requirement for user-side bench calibration, facilitating rapid deployment in predictive maintenance and machinery protection programs.

Technical Characteristics and Construction

• API 670 Compliance: Fully adheres to industry standards for linear range, accuracy, and interchangeability, making it suitable for high-reliability permanent installations.

• Superior Signal Integrity: Utilizes gold-plated brass and beryllium copper connectors to maintain a stable 50-ohm impedance, effectively minimizing signal loss in electrically noisy environments.

• Ruggedized Housing: The Proximitor sensor is encased in an A308 aluminum alloy housing, providing excellent corrosion resistance and electromagnetic shielding.

• Backward Compatibility: Designed for seamless integration with legacy non-XL 3300 series components, including compatibility with 5 mm probes when space constraints prevent the use of 8 mm hardware.

• Interchangeability: Allows for the replacement of individual components (probe, cable, or sensor) without the need for manual system recalibration or matching.

• Versatile Measurement Support: Provides high-fidelity data for fluid-film bearing machinery, including radial vibration, thrust position, and tachometer/speed sensing.
