330130-085-01-05 Bently

I. Product Introduction
Bently 330130-085-01-05 is a high-precision non-contact eddy current probe launched by Bently Nevada, a U.S.-based brand. As a core monitoring product of the 330130 series, it is specifically designed for shaft vibration, axial displacement and position monitoring of rotating machinery, serving as a core sensing component in condition monitoring systems for critical equipment in power, petrochemical, metallurgical and other industries. Based on the mature eddy current induction principle, this probe can accurately collect data such as radial vibration and axial movement of the rotating shaft without contacting the measured part, featuring high sensitivity, excellent measurement accuracy and strong anti-interference capability. It can real-time capture subtle state changes during equipment operation, providing reliable data support for predictive maintenance and fault early warning of equipment. With an industrial-grade reinforced sealed structure and a protective design resistant to high and low temperatures and oil pollution, it is suitable for harsh industrial environments with high temperature, high vibration and heavy dust. It can be seamlessly compatible with Bently 3300 and 3500 series monitoring frames, and is widely used in turbines, generators, compressors and other rotating equipment, effectively avoiding equipment failures, extending service life and reducing operation and maintenance costs.
