Product Overview

The Bently Nevada 330103-03-06-05-02-00 is a precision eddy current proximity probe engineered for the 3300 XL series monitoring platform. This non-contacting sensor is designed to observe shaft motion and position by measuring the static and dynamic gap between the probe tip and a conductive target. As a fundamental component of Turbine Supervisory Instrumentation (TSI), this 8mm probe provides the raw displacement signal necessary for calculating radial vibration and axial thrust position. This specific configuration features an M10 x 1 metric thread with a 30mm unthreaded length and a 60mm total case length, making it ideal for standard bearing housing installations where a medium-depth reach is required.

Critical Machinery Deployment and Industrial Utility

This 8mm proximity probe is a cornerstone for monitoring the health of high-speed rotating assets such as centrifugal pumps, steam turbines, gas compressors, and industrial fans. The 60mm metric case is a standard choice for European-manufactured machinery, providing sufficient length to pass through bearing caps while maintaining a secure mount. It is primarily utilized to identify mechanical faults such as shaft unbalance, misalignment, or bearing wear by tracking radial vibration. Furthermore, it serves as a critical sensor for axial thrust monitoring to prevent internal rotor-to-stator contact. By delivering a deterministic signal to a 3300 XL Proximitor and a 3500 series rack, the 330103-03-06-05-02-00 enables automated machinery protection and proactive predictive maintenance.
