Bently Nevada 330104-01-05-50-02-05 3300 XL 8 mm Proximity Probe, Metric

Why Choose the Bently Nevada 330104-01-05-50-02-05 for Vibration Monitoring?

When rotating machinery experiences unexpected vibration, unplanned downtime and costly repairs follow. The Bently Nevada 330104-01-05-50-02-05 3300 XL 8 mm Proximity Probe provides precise, reliable shaft displacement measurement to help you avoid those failures. Designed for demanding industrial environments, this probe delivers consistent performance with a linear range of 2 mm (80 mils) and a recommended gap setting of -9 Vdc for radial vibration applications.

Industry Applications

This probe excels in critical rotating machinery monitoring — turbines, compressors, pumps, and motors. In oil and gas facilities, the ATEX and IECEx approvals allow installation in hazardous areas (Class I, Zone 0) when used with intrinsic safety barriers per drawing 141092. The 2 mm linear range captures radial vibration and axial position with high accuracy, helping maintenance teams detect early signs of bearing wear or shaft misalignment.

Installation & Setup Guidance

For reliable measurements, mount the probe with the recommended gap setting of -9 Vdc (approximately 1.27 mm or 50 mils from the target). Use 3-conductor shielded triad cable for field wiring, sized 0.2 to 1.5 mm² (16 to 24 AWG). The maximum field wiring length between the Proximitor sensor and the monitor is 305 meters (1,000 feet). Ensure the probe case thread engages no more than 15 mm to avoid mechanical interference.

Maintenance & Reliability

Regular inspection of the probe tip and cable is essential. The PPS tip resists many chemicals, but avoid exposure to temperatures below -34°C (-30°F) as this may cause premature failure of the pressure seal. The probe sealing material includes a Viton O-ring; verify seal integrity periodically. For extended temperature applications, use the extended range probe variant to protect the cable and connector.

Compatibility & Integration

The 330104-01-05-50-02-05 is designed for use with Bently Nevada 3300 XL Proximitor sensors of matching 5-meter cable length. It integrates seamlessly with Bently Nevada monitoring systems for real-time vibration data acquisition. For non-incendive installations, refer to drawing 140979 for Class I, Division 2 applications.
