Precision Monitoring for Compact Rotating Machinery
The Bently Nevada 330901-00-90-10-02-05 3300 NSv Proximity Probe is a specialized eddy-current vibration sensor engineered for installations where space is limited and conventional 8 mm probes may experience side-view interference. The 3300 NSv series is particularly suitable for small shafts, narrow mounting locations, and compact rotating equipment.
Designed for high reliability in critical asset monitoring systems, this probe delivers accurate shaft vibration, axial position, and Keyphasor measurements while maintaining excellent signal stability in demanding industrial environments. Its narrow side-view sensing technology allows engineers to monitor equipment that would otherwise be difficult to instrument.

Technical FAQs
1. What is the primary purpose of this probe?
It is used to measure shaft vibration, shaft position, speed reference, and machine condition in rotating equipment.
2. What does NSv stand for?
NSv means Narrow Side View, referring to the probe's reduced sensitivity to surrounding metal structures.
3. Is this probe suitable for small shafts?
Yes. It was specifically developed for shafts smaller than approximately 51 mm (2 inches).
4. Can it replace standard 3300 XL probes?
Not always. The NSv series is a specialized design and should only be used where compatibility requirements are verified.
5. What cable length is included?
This configuration includes a 1.0-meter cable.
6. Does it support hazardous area installations?
Yes. The “05” approval option indicates multiple agency approvals depending on system configuration.
7. What material is used for the housing?
AISI 304 stainless steel.
8. What industries commonly use this sensor?
Oil & gas, power generation, refrigeration, petrochemical, and process manufacturing industries.
9. Is special calibration required?
The probe must be used as part of a properly matched Bently Nevada transducer system.
10. Can probe lengths be mixed with other systems?
No. Components within Bently Nevada monitoring systems must be correctly matched for total system length and compatibility. Industry practitioners frequently emphasize that NSv components are not universally interchangeable.
