Bently Nevada 330709-000-060-50-02-00 3300 NSv Proximity Probe

Product Overview

The Bently Nevada 330709-000-060-50-02-00 is a high-precision 3300 NSv (Narrow System vent) proximity probe designed for machinery with small shaft diameters or tight installation constraints. This eddy-current sensor measures the distance between the probe tip and a conductive target, providing critical radial vibration and axial position data to the Bently Nevada 3500 monitoring system. The NSv architecture is specifically engineered to eliminate "side-viewing" interference that often occurs with standard 8mm probes in confined spaces.

Technical Specifications (Model Breakdown)

Engineering Advantages

• Narrow System Geometry: The NSv probe tip is optimized for targets as small as 5 mm (0.2 in) in diameter, making it the primary choice for monitoring small centrifugal compressors, pumps, and specialized high-speed gearboxes. Its compact design minimizes interference and maximizes measurement accuracy in constrained environments.

• Click-Loc Connector Technology: Features a gold-plated, self-locking connector system that requires no special tools for a moisture-resistant electrical bond. This design prevents signal attenuation often caused by mechanical vibration or thermal cycling in industrial environments, ensuring long-term reliability.

• Corrosion-Resistant PPS Construction: The probe tip is molded from high-performance Polyphenylene Sulfide (PPS), offering excellent chemical resistance to synthetic lubricants and high-pressure process gases. This makes it ideal for use in harsh industrial environments where other materials might degrade over time.

• High-Precision Linear Range: Maintains a stable 3.94 V/mm (100 mV/mil) scale factor when used with the appropriate 3300 NSv Proximitor, ensuring accurate vibration data even at the edges of the linear range. This precision is essential for detecting minute changes in machine condition, which can be critical in preventing costly failures.

FAQs

What is the difference between an NSv probe and a standard 3300 XL 8mm probe?
The NSv probe is specifically designed for smaller targets and tighter spaces. While an 8mm probe requires a larger target area to maintain its magnetic field, the NSv system provides high resolution on small-diameter shafts where a larger probe would experience signal distortion or "side-viewing" interference.

Can I use this probe with a 5.0-meter extension cable?
The "50" in the part number indicates the probe has an integral 5.0-meter cable. If your system is configured for a 5.0-meter total electrical length, you connect the probe directly to the Proximitor. For a 7.0-meter or 9.0-meter system, an additional extension cable is required to reach the total configured length.

Is this a genuine Bently Nevada original part?
We supply the 330709-000-060-50-02-00 in 100% brand new, original condition. Each unit arrives in original factory packaging with a unique, traceable serial number and a factory calibration datasheet to ensure authenticity and performance.

Does this probe require a specific Proximitor sensor?
Yes. The 330709 series is an NSv system and must be paired with a 3300 NSv Proximitor. It is not compatible with 3300 XL 5mm, 8mm, or 11mm Proximitors, as the scale factors and internal calibrations differ significantly, which could result in incorrect data if mismatched.
