Bently Nevada 330104-15-25-10-02-00 3300 XL 8 mm Proximity Probe Metric

Introduction

When your rotating machinery demands precise vibration and position monitoring, the Bently Nevada 330104-15-25-10-02-00 delivers reliable performance. This 3300 XL 8 mm proximity probe, metric version, is engineered for harsh industrial environments. Its robust design includes a polyphenylene sulfide (PPS) tip and an AISI 303 or 304 stainless steel case, ensuring durability in demanding applications.

Technical Specifications Breakdown

This probe 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). The nominal probe DC resistance (RPROBE) is 7.59 ± 0.50 ohms for the 1.0-meter length. Operating temperature spans -52°C to +177°C (-62°F to +350°F) for the standard probe, with extended range options available for the tip and cable. The probe case thread is M10x1, with a maximum thread engagement of 15 mm. Weight is 323 g/m (11.4 oz).

Industry Applications

In turbomachinery, compressors, and pumps, the 330104-15-25-10-02-00 provides critical shaft vibration and position data. Its 2 mm linear range suits radial and axial measurements in high-speed rotating equipment. The probe's ability to seal differential pressure between tip and case makes it suitable for environments where pressure variations occur. The Viton O-ring sealing material supports reliable operation under these conditions.

Installation & Setup Guidance

Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) conductors, preferably a three-conductor shielded triad cable with tinned ends. Maximum cable length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). For high-frequency applications, refer to the frequency response graphs for signal rolloff. Ensure the probe tip is properly gapped to the recommended -9 Vdc setting for optimal linearity.

Maintenance & Reliability

The probe's PPS tip resists chemical attack and wear, while the stainless steel case withstands corrosion. Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. Less than a 3% change in Average Scale Factor (ASF) occurs when tested in 93% humidity per IEC standard 68-2-3 for up to 56 days. Regular inspection of the cable and connector integrity is recommended.

Compatibility & Integration

This probe works with Bently Nevada 3300 XL Proximitor Sensors and 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, verify the unthreaded length (150 mm), overall case length (250 mm), total length (1.0 meter), and connector type (miniature coaxial ClickLoc).
