Restricted Clearance Probe | Bently Nevada 330901-00-16-05-02-CN

Product Overview

The Bently Nevada 330901-00-16-05-02-CN belongs to the specialized 3300 XL NSv (Near Surface)* series, specifically engineered for machinery with restricted installation clearances. This eddy current proximity probe excels in monitoring fluid-film bearing machines, providing critical radial vibration, axial position, and Keyphasor* speed measurements. It targets small-diameter shafts (under 51 mm) where standard 8mm probes fail to maintain linearity due to target curvature. We offer this unit as 100% Brand New and Original in Factory Packing, ensuring high-fidelity signal acquisition for your most compact centrifugal and refrigeration compressors.

Technical Specifications

The NSv system utilizes advanced molding and connector technology to ensure performance stability in high-temperature industrial zones.

Engineering Advantages

• Superior Rejection of Side-View Interference: The NSv (Near Surface) design minimizes the "side-view" effect. This allows the probe to be installed in narrow tapped holes or recessed mounting brackets without picking up false signals from the surrounding metal, a common issue with standard 8mm probes.

• Optimized for Small Target Geometry: Standard probes often suffer from a distorted scale factor when measuring small, curved shafts. The 330901-00-16-05-02-CN utilizes a modified tip and coil design to provide a linear output even on shafts with significant curvature.

• Hermetically Sealed PPS Tip: The probe tip uses molded Polyphenylene Sulfide (PPS). This high-performance thermoplastic resists degradation from synthetic lubes, refrigeration gases, and aggressive chemicals, maintaining the integrity of the sensing coil over years of operation.

• Secure ClickLoc Connectivity: The gold-plated ClickLoc connector provides a vibration-resistant, low-impedance connection. The "click" mechanism confirms a secure lock, preventing accidental disconnection in high-vibration environments.

• Interchangeable System Architecture: The probe integrates seamlessly with the 3300 XL NSv Proximitor Sensor*. This modular design allows you to replace the probe without the need for time-consuming recalibration of the associated monitor module.

FAQs

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

  No. You must pair the 330901 NSv probe with a specific 3300 XL NSv Proximitor. Using a standard XL Proximitor will cause significant calibration errors and inaccurate vibration readings.

• What is the primary application for the 160mm case length?

  The 160mm case length (option -16) provides the necessary reach for deep-hole mounting through machinery casings or bearing housings, ensuring the probe tip reaches the target shaft without requiring external extensions.

• Does this probe support speed monitoring?

  Yes. When configured as a Keyphasor* sensor, this probe provides the precise timing pulses required for shaft speed measurement and synchronous vibration analysis in the Bently Nevada 3500 system.

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

  The "-CN" indicates the product meets specific regional approvals while maintaining identical technical performance to the standard model. It ensures compliance for projects requiring international certifications.
