Bently Nevada 330104-03-09-50-02-00 3300 XL 8 mm Proximity Probe

Product Overview

When unplanned downtime threatens rotating machinery, the Bently Nevada 330104-03-09-50-02-00 3300 XL 8 mm Proximity Probe delivers precise shaft displacement measurements. This metric probe, part of the trusted 3300 XL series, features a 5.0-meter (16.4 feet) cable with a miniature coaxial ClickLoc connector. Designed for use with the 5 meter Proximitor sensor, it ensures accurate vibration and position monitoring in critical applications like turbines, compressors, and pumps.

Key Specifications

The 330104-03-09-50-02-00 offers a linear range of 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target. The recommended gap setting for radial vibration is -9 Vdc, corresponding to about 1.27 mm (50 mils). Its probe case thread is M10 x 1, with a maximum thread engagement of 15 mm. The probe tip material is polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel. Nominal probe DC resistance is 8.73 ± 0.50 ohms for the 5.0 m length. Operating temperature range is -52°C to +177°C (-62°F to +350°F) for the standard probe.

Industry Applications

This proximity probe excels in heavy industries where machinery health is paramount. In power generation, it monitors turbine shaft vibration to prevent catastrophic failures. In oil and gas, it tracks compressor and pump shaft position, enabling predictive maintenance. The probe's robust stainless steel case and PPS tip withstand harsh environments, while the 5.0-meter cable length suits installations where the sensor must be placed away from the machine.

Installation & Setup Guidance

Proper installation ensures reliable data. Use 0.2 to 1.5 mm² (16 to 24 AWG) tinned field wiring with a three-conductor shielded triad cable. The maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). For radial vibration applications, set the gap to -9 Vdc. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring. Note that probes are not pressure tested before shipment.

Maintenance & Reliability

To maximize service life, avoid exposing the probe to temperatures below -34°C (-30°F), which may cause premature pressure seal failure. The probe's relative humidity performance shows less than a 3% change in Average Scale Factor (ASF) after 56 days at 93% humidity per IEC 68-2-3. Regular inspection of the cable and connector for damage is recommended. For safety-rated installations, follow the manufacturer's guidelines for periodic testing.

Compatibility & Integration

This 5-meter probe is designed exclusively for use with the 5 meter Proximitor sensor. It supports intrinsically safe installations when used with zener barriers per drawing 141092 or galvanic isolators, achieving Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga ratings. For non-incendive circuits per drawing 140979, it meets Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc. Always verify compatibility with your monitoring system before ordering.

Buying Guide

Before purchasing the 330104-03-09-50-02-00, confirm your required cable length, thread size, and agency approvals. This model includes a miniature coaxial ClickLoc connector and standard cable. If you need a pressure seal test, contact the custom design department.
