Product Overview
The Bently Nevada 330709-000-050-50-02-00 is a high-precision 3300 NSv (Narrow System vent) proximity probe designed for machinery with small shaft diameters or limited installation space. This eddy-current sensor measures static (gap) and dynamic (vibration) distances between the probe tip and a target rotor. It is a critical component of the 3500 Monitoring System, providing real-time data for radial vibration, axial thrust, and speed measurements in safety-critical turbomachinery.

Engineering Advantages
-
Narrow System Geometry: The NSv design is optimized for small targets and tight mounting constraints where standard 8mm probes would experience side-viewing interference or "sunken" signal errors, making it ideal for smaller machinery.
-
Superior Chemical Resistance: The probe tip is made from high-performance Polyphenylene Sulfide (PPS), ensuring excellent resistance to corrosive industrial lubricants and high-pressure environments, crucial for long-term reliability in harsh conditions.
-
Gold-Plated Click-Loc Connectors: The probe features specialized connectors that require only finger-tightening while ensuring a moisture-resistant, vibration-proof electrical bond, which enhances the stability and durability of the connection.
-
Precision Linear Range: Maintains a highly linear voltage-to-distance relationship over its calibrated range, ensuring accurate vibration data even during thermal expansion or high-speed shaft excursions. This results in more consistent and reliable measurements across a variety of operational conditions.
FAQs
What is the difference between an NSv probe and a standard 3300 XL 8mm probe?
The NSv (Narrow System vent) probe is specifically designed for smaller shaft diameters and tighter spaces. It has a smaller linear range than the 8mm system but provides better resolution on small targets, where a larger probe’s magnetic field could distort the measurement.
Can I use this probe with a 3300 XL Proximitor?
The 330709 series must be matched with the corresponding 3300 NSv Proximitor Sensor. Interchanging NSv probes with 3300 XL 5mm or 8mm Proximitors will result in incorrect calibration and inaccurate vibration readings.
Is this a genuine Bently Nevada original part?
We supply the 330709-000-050-50-02-00 in 100% brand new, original condition. Each probe is shipped in original factory packaging with a traceable serial number and a calibration datasheet for guaranteed authenticity and performance.
Does the 5.0-meter total length include the extension cable?
No, the "50" in the part number indicates the probe's integral cable length is 5.0 meters. If your system requires a total length of 7 or 9 meters, you must select the appropriate Proximitor and extension cable to match this 5-meter probe.
