330905-00-03-10-02-CN Bently Nevada High-Precision Proximity Probe

Product Overview

The Bently Nevada 330905-00-03-10-02-CN represents the pinnacle of proximity sensing technology for critical machinery protection. This 3300 NSv series probe is specifically designed for environments with tight clearances and small-diameter shafts where standard sensors fail. With a total product weight of 0.22 kg and a 30mm stainless steel case, it delivers high-fidelity vibration data with a 5μm resolution, ensuring maximum uptime for process compressors and turbines.

Technical Configuration

Advanced Material Science

The 330905-00-03-10-02-CN is constructed to withstand the most aggressive industrial conditions. The probe tip is molded from high-grade PPS (Polyphenylene Sulfide) polymer with a UL94 V-0 flame rating, while the 304 Stainless Steel case provides a 650 MPa yield strength. This combination, paired with a Viton seal capable of 15MPa pressure retention, ensures reliable performance in high-pressure and chemically corrosive zones.

Precision Signal Integrity

Engineered for high-speed machinery, this probe offers a 0-10kHz frequency bandwidth and a rapid 22ms response time. The system features 50Ω impedance matching and 500V surge protection, safeguarding your 3500 or 3700 series monitoring racks from electrical transients while maintaining ±0.12% full-scale accuracy.

Technical Specifications

Installation & Maintenance Guide

For certified performance, the 330905-00-03-10-02-CN requires a target surface finish of 0.8μm Ra. During installation, ensure the M10x1 threads are tightened to a calibrated torque of 5 N·m. Maintaining an axial alignment tolerance of ±0.25mm is critical for preventing signal clipping. The IP67 rating is only guaranteed when the Miniature coaxial ClickLoc connector is properly seated and environmental seals are intact.

Engineering Advantages

The "-CN" designation indicates a specialized configuration optimized for regional industrial standards while remaining 100% signal compatible with the Bently Nevada 3300 XL NSv system. This probe provides 12% better linear range than legacy models, allowing for greater flexibility in gap settings and reducing the risk of probe-to-target contact during machine thermal expansion.
