Genuine Bently Nevada 330901-00-50-05-02-00 NSv Proximity Probe

Product Overview

The 330901-00-50-05-02-00 is an industrial-grade 3300 NSv Proximity Probe designed for vibration and position monitoring in confined spaces. Part of the Bently Nevada transducer line, this probe is specifically optimized for small-shaft applications where standard probes cannot fit. It features a robust AISI304 stainless steel case and a PPS (polyphenylene sulfide) polymer tip, ensuring exceptional thermal stability and chemical resistance. With its integrated ClickLoc connector and 0.5-meter coaxial cable, this probe delivers reliable, high-impedance stability for critical machinery protection systems.

Technical Configuration

Material and Engineering Integrity

This proximity probe is built to withstand harsh industrial environments. The probe tip is constructed from high-performance PPS polymer, capable of maintaining structural integrity up to 220°C, while the Viton O-ring provides a pressure-resistant seal for demanding applications. The cable is insulated with FEP (Fluorinated Ethylene Propylene), offering superior resistance to flames and corrosive chemicals. For secure installation, the ClickLoc connector is designed for a recommended torque of 5.1 N•m, ensuring a vibration-proof connection between the probe and the extension cable.

Technical Specifications

Installation & Maintenance Guide

To ensure accurate data, the probe must be installed with a thread engagement limit of no more than 0.375 inches. During mounting, avoid sustained exposure to temperatures below -34°C if a pressure seal is required, as this may affect the O-ring elasticity. The 75Ω coaxial cable provides ±0.5% impedance stability, which is vital for maintaining signal clarity over time. When connecting the module, use a calibrated torque wrench to apply the recommended 5.1 N•m to the ClickLoc connector, preventing signal intermittent issues caused by over or under-tightening.

Engineering Advantages

• Corrosion Resistance: The AISI304 SST housing protects internal electronics from moisture and oxidation in industrial settings.
• High-Temperature Tip: The PPS polymer tip allows for close-proximity monitoring of hot rotating shafts without deformation.
• Precise Impedance: The high-quality FEP cable ensures minimal signal loss, maintaining a consistent 75Ω impedance.
• Compact Form Factor: Specifically designed for NSv (Narrow Side View) applications, making it ideal for small centrifugal compressors and pumps.

Technical FAQs

Q1: What does the "NSv" designation signify?
A1: NSv stands for Narrow Side View, indicating that this probe is designed for use with smaller targets or in areas with limited side clearance compared to standard 3300 XL probes.

Q2: Is this probe compatible with standard 3300 XL extension cables?
A2: No, 3300 NSv probes require specific NSv Proximitor sensors and extension cables to ensure correct linear scale factor and calibration.

Q3: Does the weight include the cable?
A3: Yes, the total assembly weight of 14-150g (depending on specific lead length) accounts for both the probe head and the 0.5-meter cable assembly.
