Bently Nevada 330900-70-05 Product Overview
The 330900-70-05 is a proximity vibration monitoring component belonging to the 3300 NSv Proximity Transducer System. It is designed for continuous shaft vibration and shaft position measurement in rotating machinery where installation space is limited or where compact transducer dimensions are required.
Compared with conventional eddy-current proximity systems, the 3300 NSv Series is optimized for applications involving small machines, compact bearing housings, gearboxes, centrifugal compressors, pumps, expanders, and auxiliary rotating equipment. The transducer system delivers stable and repeatable measurement performance while maintaining excellent resistance to industrial vibration, oil contamination, dust, humidity, and electromagnetic interference.
Its compact construction allows installation in locations where standard-sized proximity probes cannot be mounted. This makes it an ideal solution for retrofit projects as well as new equipment installations requiring precise shaft displacement monitoring.
The product has been engineered for long-term continuous operation in demanding industrial environments, providing reliable vibration signals to machinery protection systems, condition monitoring systems, PLCs, DCS platforms, and turbine supervisory instrumentation.

Product Features
The 330900-70-05 is specifically developed for precision shaft vibration monitoring in confined installation environments. The compact probe body significantly reduces installation difficulty while maintaining excellent measurement stability.
Its eddy-current sensing technology enables completely non-contact measurement. Since there is no physical contact with the rotating shaft, there is no mechanical wear during operation, resulting in improved reliability and extended service life.
The sensor provides highly stable output signals even under severe industrial conditions. Temperature changes, oil contamination, dust, humidity, and continuous vibration have minimal influence on measurement accuracy.
Its rugged stainless-steel construction provides excellent corrosion resistance, allowing the product to perform reliably in petrochemical plants, offshore platforms, power stations, steel mills, mining facilities, and manufacturing plants.
The product integrates easily with machinery protection systems and condition monitoring platforms, reducing engineering complexity during installation and commissioning.
