Bently Nevada 330905-00-03-10-02-05 | 1.0m NSv Proximity Probe

Product Overview

The Bently Nevada 330905-00-03-10-02-05 is a high-precision 3300 NSv proximity probe engineered for reliable vibration and position monitoring in confined industrial environments. This M10X1 threaded sensor features a 30mm overall case length and weighs approximately 0.22 kg. Designed with advanced Polyphenylene Sulfide (PPS) tips and AISI 304 Stainless Steel housing, it provides significantly higher chemical resistance than legacy RAM probes, making it the preferred choice for process compressor and turbine applications.

Technical Configuration

Precision for Small Shafts

The 3300 NSv series is optimized for applications where target sizes are limited, particularly on shaft diameters smaller than 13 mm (0.5 in). Its superior side-view characteristics reduce interference from surrounding metal, ensuring high signal stability. This configuration includes a 1.0-meter total length cable equipped with a Miniature coaxial ClickLoc connector for a secure, vibration-resistant electrical connection.

Extreme Environmental Durability

Built to perform in the harshest industrial conditions, the probe maintains operational integrity in temperatures ranging from -52°C to +177°C. The internal Viton O-ring ensures a robust seal against differential pressure, while the FEP-insulated 75 Ω coaxial cable protects signal purity across field wiring lengths up to 305 meters when paired with a Proximitor sensor.

Technical Specifications

Installation & Maintenance Guide

Mount the M10X1 probe case using the recommended torque of 7.5 N•m (66 in•lb) for the first three threads to ensure a secure fit that resists machine vibration. Maintain a minimum bend radius of 25.4 mm (1.0 in) for the coaxial cable to prevent internal conductor damage. For optimal signal accuracy, the gap should be set at approximately 1.0 mm (40 mils). Periodically verify the probe DC resistance; it should measure 4.2 ± 0.5 ohms for this 1.0m configuration.

Engineering Advantages

The 3300 NSv series offers complete mechanical and electrical interchangeability with previous Bently Nevada 3300 RAM systems, enabling easy facility upgrades. The "Multiple Approvals" (-05) option ensures the probe meets global safety standards for deployment in hazardous areas. Its increased chemical resistance is specifically beneficial in process compressor environments where exposure to aggressive hydrocarbons is common.
