Product Overview

The 330101-00-10-10-01-00 is a high-performance 8mm eddy current proximity probe part of the Bently Nevada 3300 XL series. This non-contacting sensor is specifically engineered to measure the physical gap between the probe tip and a conductive target surface, such as a rotating shaft. By translating this distance into a precise electrical signal, it enables the real-time monitoring of radial vibration and axial position in critical industrial machinery.

This specific probe configuration is widely utilized in Turbine Supervisory Instrumentation (TSI) systems to protect fluid-film bearing assets. Its design adheres to the rigorous API 670 standards, ensuring consistent accuracy, linear range, and thermal stability across a broad spectrum of industrial environments. Whether used for thrust position tracking or as a Keyphasor phase reference, the 330101-00-10-10-01-00 provides the foundational data necessary for machinery protection and predictive maintenance.

Key Technical Characteristics

• Universal Interchangeability: As a core component of the 3300 XL transducer system, this probe is fully interchangeable with other XL-series extension cables and Proximitor sensors without the need for manual bench calibration.

• Precision Threading: Features a 3/8-24 UNF threaded body designed for secure mounting and fine-tuned gap adjustments during installation.

• Advanced Connector Design: Equipped with a gold-plated Miniature Coaxial ClickLoc connector, providing a vibration-resistant electrical junction that requires only finger-tightening.

• Extreme Thermal Resilience: Capable of maintaining signal integrity in temperatures ranging from -51°C to +177°C, making it suitable for high-heat turbine environments.

• System Versatility: Offers backwards compatibility with legacy 3300 series 5mm and 8mm components, facilitating cost-effective system upgrades.

• Linear Signal Output: Produces an output voltage directly proportional to the gap, delivering a standard scale factor of 7.87 V/mm (200 mV/mil).
