Bently Nevada 330104-03-12-05-02-05 3300 XL 8 mm Proximity Probe

Introduction

When rotating machinery experiences unexpected vibration, unplanned downtime and costly repairs often follow. The Bently Nevada 330104-03-12-05-02-05 3300 XL 8 mm Proximity Probe provides reliable, non-contact shaft displacement and vibration measurements. This probe is part of the proven 3300 XL series, designed for continuous monitoring in demanding industrial applications. Made in the U.S.A., it offers robust construction and consistent performance.

Technical Specifications Breakdown

The 330104-03-12-05-02-05 features a 30 mm unthreaded length and a 120 mm overall case length, with a total length of 0.5 meter (1.6 feet). It uses a miniature coaxial ClickLoc connector with standard cable. The probe tip is made of polyphenylene sulfide (PPS), and the probe case is AISI 303 or 304 stainless steel (SST). The probe is designed to seal differential pressure between the tip and case using a Viton O-ring. Agency approvals include CSA, ATEX, and IECEx. The nominal probe DC resistance (RPROBE) for the 0.5 meter length is 7.45 ± 0.50 ohms.

Industry Applications

This proximity probe excels in monitoring radial vibration and axial position of shafts in turbines, compressors, pumps, and motors. Its PPS tip and stainless steel case withstand harsh conditions, while the CSA, ATEX, and IECEx approvals make it suitable for hazardous area installations. The 0.5 meter cable length allows flexible placement near the measurement point.

Installation & Setup Guidance

Install the probe into a threaded M10 x 1 hole. Ensure the target surface is clean and made of AISI 4140 steel for optimal accuracy. Gap the probe to 1.27 mm (50 mils) per standard practice. Connect the miniature coaxial ClickLoc connector to a compatible 3300 XL extension cable and Proximitor sensor. Verify power supply is between -17.5 Vdc and -26 Vdc when using a non-incendive circuit per installation drawing 140979.

Maintenance & Reliability

Periodically inspect the probe cable and connector for wear or damage. Keep the probe tip and target surface clean from debris and contaminants. The Viton O-ring seal helps maintain pressure integrity; replace it if leakage is suspected. Regular verification of gap voltage ensures consistent measurement accuracy.

Compatibility & Integration

This probe works exclusively with Bently Nevada 3300 XL 8 mm Proximitor sensors and extension cables. The system delivers accurate vibration and position signals to monitoring systems. Verify that the total system includes only 3300 XL 8 mm components for guaranteed performance.
