Bently Nevada 330901-00-32-05-02-CN Small Target Sensor

Product Overview

The Bently Nevada 330901-00-32-05-02-CN is a specialized 3300 XL NSv* (Near Surface) Proximity Probe engineered for machinery with restricted installation clearances and small targets. This probe addresses the specific physical constraints found in centrifugal air compressors, refrigeration units, and process gas compressors where standard 8mm probes cannot fit. It detects minute shaft radial vibration and axial position changes with high precision, specifically on shafts smaller than 51 mm (2 inches). We supply this unit as 100% Brand New and Original (Made in USA), ensuring your high-speed rotating assets remain protected by authentic Bently Nevada eddy current technology.

Technical Specifications

The 3300 XL NSv probe utilizes advanced materials to maintain signal stability in chemically aggressive and high-pressure environments.

Engineering Advantages

• Optimized for Restricted Clearances: The NSv (Near Surface) design allows for accurate vibration measurement in tight internal cavities where standard probes suffer from side-view interference. This makes it the primary choice for compact, high-speed gearboxes and compressors.

• Small Target Precision: Standard probes often provide nonlinear output when measuring small shafts. The 330901-00-32-05-02-CN utilizes a specialized tip geometry that maintains a linear scale factor even on shafts with significant curvature or limited target area.

• Resilient PPS Tip Construction: The probe tip features molded Polyphenylene Sulfide (PPS). This high-performance thermoplastic resists degradation from synthetic lubes and aggressive process gases, ensuring the hermetic seal remains intact over years of continuous operation.

• ClickLoc Interconnect System: The miniature coaxial connector utilizes the ClickLoc mechanism. This gold-plated connection prevents accidental loosening due to machine vibration and ensures consistent electrical impedance for the Proximitor* circuit.

• Superior Side-View Rejection: The NSv series minimizes the "side-view" effect where the probe picks up signals from the surrounding mounting bracket rather than the actual shaft. This improves the accuracy of radial vibration data in complex housing designs.

FAQs

• Can I use the 330901 NSv probe with a standard 3300 XL Proximitor?

  No. The NSv probe requires a specific 3300 XL NSv Proximitor Sensor. Using a standard 3300 XL Proximitor will result in incorrect calibration and an inaccurate scale factor (mV/mil).

• When should I choose an NSv probe over a standard 8mm probe?

  Select the NSv series when your shaft diameter is less than 51 mm (2 inches) or when the probe must be installed in a very narrow hole where side-wall interference would distort the signal of a standard probe.

• Is this probe compatible with the 3500 Machinery Protection System?

  Yes. When paired with the correct NSv Proximitor and extension cable, the output signal integrates directly with the Bently Nevada 3500/40 or 3500/42M monitor modules.

• What is the significance of the "-CN" suffix?

  The "-CN" suffix indicates that the product meets specific regional agency approvals and certifications, ensuring compliance for international projects while maintaining the exact same high-performance technical specs as the standard model.
