Bently Nevada 330708-00-20-50-02-05 3300 XL 11 mm Proximity Probe

The Bently Nevada 330708-00-20-50-02-05 is a high-accuracy 11 mm proximity probe system designed for reliable vibration and position monitoring in rotating machinery.

Technical Overview

The Bently Nevada 330708-00-20-50-02-05 serves as a precision-engineered 11 mm proximity transducer system, specifically developed to monitor vibration and displacement in critical rotating machinery. By utilizing advanced eddy current technology, this probe detects the distance between the sensor tip and the target shaft without physical contact. Consequently, operators obtain highly accurate real-time data regarding radial position, shaft orbit, and axial displacement in fluid-film bearing environments.

System Performance and Reliability

Bently Nevada designed the 3300 XL 11 mm system to withstand demanding industrial conditions. Because the probe incorporates patented TipLoc and CableLoc technologies, it offers exceptional structural integrity, supporting a cable pull strength of up to 330 N. Furthermore, the system provides superior immunity to Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) without the need for additional shielding. As a result, users benefit from a more stable signal output in environments dense with electronic noise.

Installation and Integration

Maintenance teams appreciate the simplified installation process afforded by the tool-free SpringLoc terminals. Furthermore, the compact Proximitor sensor footprint allows technicians to integrate the unit into both modern and legacy control panels with minimal spatial requirements. Additionally, the system maintains full interchangeability with existing 3300 series components. Consequently, plant engineers can perform upgrades or replacements with greater ease. Finally, for applications involving extreme heat, the platform supports Extended Temperature Range (ETR) options, ensuring consistent monitoring performance up to 260°C.
