Product Overview

The Bently Nevada 330103-00-05-50-02-CN is a comprehensive eddy current proximity transducer system engineered for high-precision machinery protection. This integrated solution provides non-contacting measurement of shaft vibration and position, translating the physical gap between the probe tip and a conductive target into a linear voltage signal. As a vital component of Turbine Supervisory Instrumentation (TSI), it allows for real-time monitoring of critical rotating equipment.

This "CN" specific configuration belongs to the 3300 XL 8mm family, renowned for superior temperature stability and measurement accuracy. It is extensively utilized in the oil, gas, and petrochemical sectors to safeguard fluid-film bearing machines. Beyond vibration analysis, the system provides essential data for Keyphasor® reference signals and rotational speed measurements, ensuring comprehensive oversight of machinery health and operational safety.

Technical Characteristics and Performance

• API 670 Standard Alignment: Specifically designed to meet or exceed American Petroleum Institute (API) 670 requirements for mechanical configuration, linear range, and thermal stability in machinery protection systems.

• Universal Interchangeability: A hallmark of the 3300 XL architecture, all components—including the probe, extension cable, and Proximitor® sensor—are fully interchangeable. This eliminates the need for manual bench calibration or component matching during field replacement.

• Signal Integrity: Delivers a highly accurate output voltage proportional to the distance between the sensor and the observed surface, maintaining linearity even in fluctuating temperature environments.

• Enhanced Backward Compatibility: Designed for versatile system integration, this module is compatible with legacy non-XL 3300 series 5mm and 8mm components, facilitating cost-effective facility upgrades.

• Mounting Versatility: While optimized for 8mm applications, the system electronics support 5mm probes for installations where restricted physical access prevents the use of standard 8mm hardware.

• Ruggedized Design: Engineered for longevity in demanding industrial conditions, featuring robust materials that resist corrosion and mechanical stress.
