Bently Nevada 330104-00-06-90-12-05 3300 XL 8 mm Proximity Probe

Product Introduction

When critical rotating machinery requires precise vibration and position monitoring, the Bently Nevada 330104-00-06-90-12-05 delivers reliable performance. This 3300 XL 8 mm proximity probe with armor provides accurate displacement measurements in harsh industrial environments. Designed for use with 3300 XL Proximitor sensors and extension cables, it forms a complete transducer system for machinery protection.

Technical Specifications Breakdown

The 330104-00-06-90-12-05 features a polyphenylene sulfide (PPS) probe tip and an AISI 303 or 304 stainless steel case for durability. The total length option of 90 indicates a 9.0-meter (29.5 feet) cable with a miniature coaxial ClickLoc connector and FluidLoc cable. Nominal probe DC resistance from center conductor to outer conductor is 9.87 ± 0.50 Ω for the 9.0 m probe. The probe is designed to seal differential pressure between tip and case using a Viton O-ring. Agency approvals include CSA, ATEX, and IECEx.

Industry Applications

This proximity probe excels in monitoring radial vibration and axial position of turbines, compressors, pumps, and motors. In oil and gas facilities, the ATEX and IECEx approvals allow installation in hazardous areas such as Class I, Zone 0 environments. The 8 mm diameter and M10 x 1 thread make it suitable for standard mounting configurations in rotating machinery.

Installation & Setup Guidance

Proper installation is critical for accurate measurements. Mount the probe with the specified gap of 1.27 mm (50 mils) when using an AISI 4140 steel target. Ensure the cable is routed without sharp bends to avoid damage. The miniature coaxial ClickLoc connector provides a secure connection to the extension cable. Verify the probe tip is clean and free of debris before installation.

Maintenance & Reliability

Routine inspection of the probe tip and cable for wear or damage helps maintain long-term reliability. The PPS tip resists chemical attack and mechanical wear. The stainless steel case withstands corrosive environments. For safety-rated installations, follow the manufacturer's guidelines for periodic testing and verification.

Compatibility & Integration

The 330104-00-06-90-12-05 is compatible with 3300 XL Proximitor sensors and extension cables. It accepts one non-contacting 3300-series 5 mm or 3300 XL 8 mm probe. The system requires a -17.5 Vdc to -26 Vdc power supply with 12 mA maximum consumption. For intrinsically safe installations, use zener barriers per drawing 141092 or galvanic isolators.

Buying Guide & Purchasing Advice

Before ordering, verify the total length option (90 = 9.0 meters) and connector type (12 = miniature coaxial ClickLoc with FluidLoc cable) match your application requirements. The agency approval option 05 includes CSA, ATEX, and IECEx certifications.
