Product Overview

The Bently Nevada 330103-00-06-50-02-00 is a high-integrity eddy current sensor belonging to the 3300 XL 8mm proximity transducer system. Engineered for non-contact displacement monitoring, this probe measures the static and dynamic distance between the sensor tip and a target shaft. This data is critical for determining radial vibration and axial (thrust) position in high-speed rotating assets. Built to satisfy API 670 standards, the 330103-00-06-50-02-00 provides the precision required for Turbine Supervisory Instrumentation (TSI), ensuring that mechanical deviations are captured before they lead to catastrophic equipment failure. This specific configuration features an M10 x 1 metric thread with a 60mm case length and a 5.0-meter total length with armored lead protection.

Strategic Industrial Utility

This 8mm proximity probe is a cornerstone for machinery protection in the oil and gas, power generation, and chemical processing industries. The 5.0-meter integrated lead length allows for direct connection to a Proximitor sensor without the need for an additional extension cable in smaller machine footprints. It is primarily utilized on centrifugal compressors, steam turbines, and large industrial motors to monitor radial vibration—detecting shaft unbalance or misalignment—and axial thrust to prevent internal rotor-to-stator contact. By feeding high-fidelity displacement signals to Bently Nevada 3500 series monitoring racks, the 330103-00-06-50-02-00 facilitates real-time safety interlocks and supports advanced predictive maintenance strategies.
