Compact NSv Proximity Probe for Tight Installation Machinery
The Bently Nevada 330910-00-13-05-02-00 3300 NSv Proximity Probe is a compact, non-contact eddy-current sensor specifically engineered for rotating machinery with restricted installation space. As part of the 3300 XL NSv Proximity Transducer System, it provides highly accurate shaft vibration, shaft position, and Keyphasor® measurements in applications where conventional 8 mm proximity probes cannot be accommodated. The NSv (Narrow Side View) design is particularly suited for centrifugal compressors, refrigeration compressors, process gas compressors, and other equipment with limited counterbore or side-view clearances.
This configuration features an M10 × 1 threaded probe, 0 mm unthreaded length, 130 mm overall case length, a 0.5 m (20 in.) integrated standard cable, and a Miniature ClickLoc™ coaxial connector. The probe is designed to operate with compatible 3300 XL NSv extension cables and 3300 XL NSv Proximitor Sensors, providing excellent interchangeability and reliable long-term performance.

Technical FAQs
1. What is the primary function of this probe?
It measures shaft vibration, shaft position, and rotational reference signals using non-contact eddy-current sensing technology.
2. What does "330910" indicate?
The 330910 model identifies an M10 × 1 threaded, armored standard-mount NSv proximity probe.
3. What does the "13" option represent?
It specifies a 130 mm overall case length.
4. What cable length is supplied?
This configuration includes a 0.5-meter (20-inch) integrated cable.
5. What connector does this model use?
It is equipped with a Miniature ClickLoc™ coaxial connector for secure, vibration-resistant connections.
6. Why choose an NSv probe instead of a standard 8 mm probe?
The NSv probe is designed for applications with limited counterbore, side-view, or rear-view clearances where standard probes cannot fit.
7. Can this probe monitor small shafts?
Yes. It is specifically designed for shafts smaller than 51 mm (2 inches) and other compact rotating components.
8. Does this probe require additional components?
Yes. It must be used with a compatible 3300 XL NSv extension cable and 3300 XL NSv Proximitor Sensor to form a complete transducer system.
9. Which industries commonly use this probe?
It is widely used in oil & gas, petrochemical, power generation, refrigeration, and industrial process plants utilizing compact rotating machinery.
10. Is this probe suitable for continuous online monitoring?
Yes. It is designed for permanent installation in machinery protection and condition monitoring systems operating continuously.
