Bently Nevada 330104-03-06-10-02-00 3300 XL 8 mm Proximity Probe

Product Overview

When critical rotating machinery requires precise vibration and position monitoring, the Bently Nevada 330104-03-06-10-02-00 delivers reliable performance. This 3300 XL 8 mm proximity probe is engineered for demanding industrial environments, offering a linear range of 2 mm (80 mils) starting at approximately 0.25 mm from the target. With a polyphenylene sulfide (PPS) probe tip and an AISI 303 or 304 stainless steel case, it withstands harsh conditions while providing accurate measurements.

Technical Specifications Breakdown

The 330104-03-06-10-02-00 features a nominal probe DC resistance of 7.59 ± 0.50 ohms at 1.0 meter length. Its operating temperature range spans -52°C to +177°C (-62°F to +350°F) for standard probes, with extended range options available for the tip up to +218°C. The probe case thread is M10x1 with a maximum thread engagement of 15 mm. Recommended gap setting for radial vibration is -9 Vdc, approximately 1.27 mm (50 mils).

Industry Applications

This probe excels in turbomachinery monitoring, including steam turbines, gas turbines, compressors, and pumps. Its ability to seal differential pressure between the probe tip and case makes it suitable for applications where pressure variations occur. The probe is designed for use with intrinsically safe zener barriers or galvanic isolators per specific drawings, enabling installation in hazardous areas such as Class I, Zone 0.

Installation & Setup Guidance

For optimal performance, mount the probe with a recommended torque of 11.2 N•m (100 in•lbf) and a maximum of 33.9 N•m (300 in•lbf). Use 3-conductor shielded triad cable with tinned field wiring, 0.2 to 1.5 mm² (16 to 24 AWG). Maximum field wiring length between the probe and monitor is 305 meters (1,000 feet). Ensure the probe is not exposed to temperatures below -34°C (-30°F) to avoid premature pressure seal failure.

Maintenance & Reliability

Regular inspection of the probe and cable for physical damage is recommended. The probe's relative humidity performance shows less than a 3% change in Average Scale Factor (ASF) when tested at 93% humidity per IEC 68-2-3 for up to 56 days. The Viton® O-ring seal maintains integrity under normal operating conditions. For extended life, avoid thermal cycling beyond the specified temperature range.

Compatibility & Integration

The 330104-03-06-10-02-00 integrates seamlessly with Bently Nevada 3300 XL Proximitor sensors and monitoring systems. It supports both standard and extended temperature range configurations. For hazardous locations, it can be installed with intrinsically safe barriers (drawing 141092) or non-incendive circuits (drawing 140979). The miniature ClickLoc coaxial connector ensures secure and reliable signal transmission.

Selection Guide & Purchasing Advice

When ordering, verify the unthreaded length (03 = 30 mm), overall case length (06 = 60 mm), total length (10 = 1.0 meter), connector type (02 = miniature ClickLoc coaxial), and agency approval option (00 = not required). The probe weight is 323 g/m (11.4 oz). For current availability and lifecycle status, contact plcmatrix.com, a trusted supplier of Bently Nevada automation components.
