Product Overview

The Bently Nevada 330101-00-45-05-01-00 is a precision-engineered 8mm eddy current proximity probe, serving as a vital sensing element for the 3300 XL series. This non-contacting transducer is designed to observe shaft vibration and axial position in high-speed rotating machinery. By measuring the physical gap between the probe tip and a conductive target, it facilitates the monitoring of radial shaft stability, thrust position, and phase reference (Keyphasor) signals.

This specific configuration features an extended 4.5-inch case length and a 3/8-24 UNF thread, making it ideal for deep-port installations where a standard-length probe cannot reach the target surface. It is a fundamental component of Turbine Supervisory Instrumentation (TSI), widely utilized in power generation, oil and gas, and petrochemical sectors to protect fluid-film bearing assets like turbines and compressors.

Technical Characteristics and Performance

• Extended Reach Construction: Features a 4.5-inch (approx. 114 mm) case length for specialized mounting requirements in thick-walled machine housings.

• Miniature ClickLoc Connectivity: Equipped with a gold-plated miniature coaxial ClickLoc connector on a 0.5-meter lead, ensuring a secure, vibration-resistant electrical junction that requires no specialized tools for assembly.

• High-Integrity Signal Transmission: Designed with a typical capacitance of 69.9 pF/m, ensuring accurate displacement signal transmission to the Proximitor sensor with minimal interference.

• Universal Match Design: Fully interchangeable with other 3300 XL system components, eliminating the need for individual component matching or bench calibration during field replacement.

• Advanced Shielding: When paired with a 3300 XL Proximitor, the system provides exceptional immunity to Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI).

• Robust Mechanical Interface: The 3/8-24 UNF threaded body allows for fine-tuned gap adjustments, while the included connector protection ensures long-term reliability in oily or humid industrial environments.
