Overview of the Probe
The Bently Nevada 330901-00-16-05-02-CN 3300 NSv Proximity Probe is a compact eddy-current transducer designed for non-contact measurement of shaft vibration, shaft position, and displacement in rotating machinery. As a member of the 3300 NSv (Narrow Side View) Proximity Transducer System, this probe is specifically engineered for installations where space is limited and conventional proximity probes cannot be accommodated.
Its narrow-profile design makes it particularly suitable for small compressors, motors, gearboxes, and other machinery with restricted mounting clearances while maintaining the measurement accuracy required for machinery protection systems.

Technical FAQs
1. What does this probe measure?
It measures shaft vibration, shaft position, and displacement using eddy-current sensing technology.
2. Is it a contact sensor?
No. It operates as a non-contact proximity probe.
3. What does NSv mean?
NSv stands for Narrow Side View, a design optimized for installations with limited mounting space.
4. What is the total length of this configuration?
The "-05" option designates a total probe length of 0.5 meters (20 inches).
5. What does the "16" code represent?
It identifies a 1.6-inch overall case length.
6. What does the "CN" suffix indicate?
The CN option refers to a country-specific approval configuration.
7. Can the probe be used independently?
No. It must operate as part of a complete 3300 NSv transducer system with compatible extension cables and Proximitor sensors.
8. What industries commonly use this probe?
Power generation, oil and gas, petrochemical processing, manufacturing, and heavy industrial facilities.
9. What connector does it use?
It uses a miniature coaxial ClickLoc connector for secure installation.
10. Why choose an NSv probe instead of a standard proximity probe?
NSv probes are specifically designed for machinery with restricted installation clearances where standard probe geometries cannot be accommodated.
