Bently Nevada 330104-01-08-50-01-IN 3300 XL 8 mm Proximity Probe

Introduction

When unplanned downtime threatens your rotating machinery, the Bently Nevada 330104-01-08-50-01-IN 3300 XL 8 mm Proximity Probe delivers precise, non-contact vibration and position measurements. This probe is engineered for harsh industrial environments where reliability is non-negotiable.

Technical Specifications Breakdown

The 330104-01-08-50-01-IN features an unthreaded length of 10 mm and an overall case length of 80 mm. The total length option of 5.0 meters (16.4 feet) provides flexibility for installation in tight spaces. The miniature coaxial ClickLoc connector with connector protector ensures a secure and quick connection. The probe tip is made of Polyphenylene sulfide (PPS), while the probe case is constructed from AISI 303 or 304 stainless steel (SST), offering excellent chemical resistance and durability. The nominal probe DC resistance is 8.73 ± 0.50 ohms at 5.0 meters. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring.

Industry Applications

This 3300 XL 8 mm probe is ideal for monitoring radial vibration and axial position in steam turbines, compressors, pumps, and generators. Its robust construction withstands high temperatures up to +232°C (for T1 temperature classification) and pressures typical in turbomachinery. The probe's PPS tip provides excellent wear resistance in continuous contact applications.

Installation & Setup Guidance

Install the 330104-01-08-50-01-IN by threading it into a standard M10 x 1 mounting hole. Ensure the target surface is clean and made of AISI 4140 steel for optimal performance. Gap the probe at 1.27 mm (50 mils) for standard calibration. Connect the ClickLoc connector to the extension cable, ensuring the connector protector is properly seated. For hazardous area installations, follow the appropriate wiring diagrams (e.g., drawing 140979 for non-incendive circuits or drawing 141092 for intrinsically safe barriers).

Maintenance & Reliability

Regularly inspect the probe cable and connector for damage. Verify the probe tip for wear or contamination. The stainless steel case and PPS tip resist corrosion and abrasion, extending service life. For safety-rated installations, periodic functional testing according to the manufacturer's safety manual is recommended.

Compatibility & Integration

The 330104-01-08-50-01-IN works exclusively with Bently Nevada 3300 XL 8 mm Proximitor Sensors and extension cables. It accepts a 3300-series 5 mm or 8 mm probe and requires a -17.5 Vdc to -26 Vdc power supply (with non-incendive circuit) or -23 Vdc to -26 Vdc (with barriers). The output resistance is 50 ohms.

Selection Guide & Purchasing Advice

Before ordering, verify the probe length, connector type, and agency approval (CN in this case). Ensure compatibility with your existing Bently Nevada monitoring system. For current availability and lifecycle status, contact plcmatrix.com, a trusted supplier of industrial automation components.
