Bently Nevada 330104-00-13-90-02-CN 3300 XL 8 mm Proximity Probe, Metric

Introduction

When a critical rotating machine begins to exhibit unexpected vibration, the ability to detect and measure shaft displacement accurately becomes paramount. The Bently Nevada 330104-00-13-90-02-CN, a 3300 XL 8 mm Proximity Probe, provides the precise, reliable data needed to diagnose and prevent costly downtime. This metric probe, part of the trusted 3300 XL series, is engineered for continuous monitoring in harsh industrial environments, offering a linear measurement range that begins at approximately 0.25 mm from the target.

Technical Specifications Breakdown

The 330104-00-13-90-02-CN is built with a polyphenylene sulfide (PPS) probe tip and an AISI 303 or 304 stainless steel case, ensuring durability in demanding conditions. Its M10x1 thread allows for secure mounting, with a maximum thread engagement length of 15 mm. The total probe length is 9.0 meters (29.5 feet), terminated with a miniature coaxial ClickLoc connector and standard cable. The nominal probe DC resistance from center conductor to outer conductor is 9.87 ± 0.50 ohms at 9.0 m. The linear range spans 2 mm (80 mils), from 0.25 to 2.3 mm (10 to 90 mils), corresponding to approximately –1 to –17 Vdc. The recommended gap setting for radial vibration is –9 Vdc, approximately 1.27 mm (50 mils).

Industry Applications

This proximity probe excels in monitoring radial vibration and axial position of rotating shafts in turbines, compressors, pumps, and motors. In a steam turbine application, the 330104-00-13-90-02-CN provides continuous shaft displacement data, enabling early detection of bearing wear or imbalance. Its robust construction and wide operating temperature range (standard probe: –52°C to +177°C) make it suitable for both indoor and outdoor installations in power generation, oil and gas, and petrochemical facilities.

Installation & Setup Guidance

Proper installation is critical for accurate measurements. Mount the probe using the M10x1 thread, ensuring the tip is positioned within the linear range (0.25 to 2.3 mm from the target). Use 3-conductor shielded triad cable with tinned field wiring, 0.2 to 1.5 mm² (16 to 24 AWG). The maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). For best frequency response, keep wiring as short as possible. When installed with intrinsically safe zener barriers per drawing 141092 or with galvanic isolators, the probe is rated Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga.

Maintenance & Reliability

The 330104-00-13-90-02-CN is designed for long-term reliability with minimal maintenance. The probe case material (AISI 303 or 304 SST) resists corrosion, and the PPS tip withstands high temperatures. However, exposing the probe to temperatures below –34°C (–30°F) may cause premature failure of the pressure seal. Regular inspection of the cable and connector for damage is recommended. The probe's humidity resistance is verified: less than a 3% change in Average Scale Factor (ASF) when tested in 93% humidity per IEC standard 68 2 3 for up to 56 days.

Buying Guide

Before ordering the 330104-00-13-90-02-CN, verify that your application requires a 9.0 m cable length and a miniature coaxial ClickLoc connector. This model includes a country-specific agency approval (CN). For replacement or new installations, confirm compatibility with your existing 3300 XL Proximitor Sensor and monitoring system. plcmatrix.com stocks this probe and can assist with availability and lifecycle status.
