Description

Technical Overview

The Bently Nevada 330103-00-02-10-02-05 Proximity Probe is a high-precision, non-contact displacement sensor engineered for continuous, real-time monitoring of shaft vibration, axial position, and differential expansion in rotating machinery. Manufactured by Baker Hughes (formerly Bently Nevada, a GE Digital company), this probe forms the foundational sensing element of the industry-standard 3300 XL and 3300 NSM proximity transducer systems. Designed to operate within rigorous industrial environments—including power generation, oil & gas, petrochemical, and marine propulsion applications—the 330103-00-02-10-02-05 delivers exceptional linearity, thermal stability, and long-term repeatability. Its robust construction features a stainless steel housing with integrated high-temperature epoxy encapsulation, enabling reliable performance across extreme temperature gradients and high-vibration conditions. The probe utilizes eddy current technology to detect minute changes in the distance between its active tip and a conductive target surface—typically a ferromagnetic shaft or collar—with sub-micron resolution. Each unit undergoes stringent factory calibration against NIST-traceable standards and is supplied with full calibration documentation, including sensitivity (mV/mil), linearity error (<±0.3% full scale), and frequency response (DC to 10 kHz). This model is offered in new, factory-fresh condition, backed by a comprehensive 24-month limited warranty covering material defects and workmanship. Originating from the United States, it complies with RoHS, CE, and ATEX directives where applicable, and meets ISO 9001:2015 quality management system requirements. With precise dimensional consistency and mechanical compatibility across legacy and next-generation Bently Nevada monitoring platforms, the 330103-00-02-10-02-05 ensures seamless integration into existing asset health monitoring infrastructures while supporting predictive maintenance strategies aligned with ISO 10816 and API 670 standards.
