Bently Nevada 330104-08-15-10-02-CN 3300 XL 8 mm Proximity Probe, Metric

Product Introduction

When reliable vibration and position monitoring is critical for rotating machinery, the Bently Nevada 330104-08-15-10-02-CN 3300 XL 8 mm Proximity Probe delivers precise measurements. This metric probe features a polyphenylene sulfide (PPS) tip and AISI 303 or 304 stainless steel case, designed for harsh industrial environments. Part of the proven 3300 XL series, it provides accurate gap and vibration data for predictive maintenance programs.

Technical Specifications Breakdown

The 330104-08-15-10-02-CN offers a linear range of 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target. The recommended gap setting for radial vibration is -9 Vdc, corresponding to about 1.27 mm (50 mils). Nominal probe DC resistance (RPROBE) from center conductor to outer conductor is 7.59 ± 0.50 Ω for the 1.0 meter length. The probe case thread is M10x1 with a maximum thread engagement of 15 mm. Operating and storage temperature for the standard probe ranges from -52°C to +177°C (-62°F to +350°F).

Industry Applications

This proximity probe excels in turbomachinery monitoring, including steam turbines, compressors, and pumps. Its 2 mm linear range and high-temperature tolerance make it suitable for bearing vibration and shaft position measurement. The PPS tip resists chemical exposure, while the stainless steel case ensures durability in high-humidity environments—less than 3% change in Average Scale Factor (ASF) after 56 days at 93% humidity per IEC 68-2-3.

Installation & Setup Guidance

Field wiring requires 0.2 to 1.5 mm² (16 to 24 AWG) conductor, using 3-conductor shielded triad cable with tinned wiring. Maximum cable length between the probe and monitor is 305 meters (1,000 feet). The miniature coaxial ClickLoc connector simplifies installation. For radial vibration, set the gap to -9 Vdc (approximately 1.27 mm). Ensure the probe tip does not contact the target during operation.

Maintenance & Reliability

The 330104-08-15-10-02-CN probe is designed for long service life. The Viton® O-ring seals the probe tip and case, but probes are not pressure tested before shipment. Exposing the probe to temperatures below -34°C (-30°F) may cause premature pressure seal failure. Regular inspection of the cable and connector for damage is recommended. For extended temperature ranges, the probe tip can operate up to +218°C (+425°F) and the cable up to +260°C (+500°F).

Compatibility & Integration

This probe works with Bently Nevada 3300 XL Proximitor sensors and compatible monitoring systems. When installed with intrinsically safe zener barriers per drawing 141092 or galvanic isolators, it meets Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga; Class 1, Groups A, B, C, D; Class II, Groups E, F, G; Class III. For non-incendive circuits per drawing 140979, it meets Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc; Class 1, Division 2, Groups A, B, C, D; and Class I, Zone 2: AEx/Ex ec IIC T5…T1 Gc.

Selection Guide & Purchasing Advice

Before ordering the 330104-08-15-10-02-CN, verify your system requirements: unthreaded length 80 mm, overall case length 150 mm, total length 1.0 meter, and connector type (miniature coaxial ClickLoc).
