Product Overview

The Bently Nevada 330903-05-19-05-02-00 is a high-precision 3300 XL NSv (Narrow Side View) Proximity Transducer designed for non-contacting vibration and position measurements. This specialized eddy-current sensor is engineered specifically for machinery where tight spatial constraints prevent the use of standard 8 mm or 5 mm probe systems. By utilizing a smaller physical footprint and a narrower sensing field, the 330903-05-19-05-02-00 effectively eliminates the "side-view" interference caused by nearby metallic surfaces or counterbore mounting. It serves as a vital sensing element within a Turbine Supervisory Instrumentation (TSI) framework, providing the raw signal required for radial vibration monitoring, axial thrust position, and Keyphasor speed measurements on critical rotating assets.

Industrial Asset Monitoring Applications

This transducer system is the industry standard for protecting small-bore machinery equipped with fluid-film bearings. It is primarily deployed on centrifugal air compressors, refrigeration chillers, and specialized process gas compressors found in petrochemical and manufacturing facilities. The 330903-05-19-05-02-00 is uniquely suited for monitoring small-diameter shafts where standard sensors suffer from target curvature errors. By delivering precise eddy-current signals to Bently Nevada 3300 or 3500 series monitoring racks, it enables the early detection of bearing wear, shaft misalignment, and mechanical unbalance. Its compact design allows it to be installed in rear-view or side-view ports where space is at a premium, ensuring that even the most compact high-speed compressors remain under constant safety surveillance.
