Selecting the Right Proximity Probe for Critical Machinery Monitoring
When evaluating vibration monitoring solutions for rotating machinery, the choice of proximity probe directly impacts measurement accuracy and system reliability. The Bently Nevada 330102-00-24-10-02-CN is a 3300 XL 8 mm Proximity Probe designed for demanding industrial environments. This guide helps you assess whether this probe meets your application requirements.
Product Overview
The 330102-00-24-10-02-CN is part of the proven 3300 XL series from Bently Nevada. It is an 8 mm proximity probe with a 3/8-24 UNF thread and armor protection. The probe features a polyphenylene sulfide (PPS) tip and a case made of AISI 303 or 304 stainless steel. It comes with a miniature coaxial ClickLoc connector and standard cable. The Country Specific Approval (CN) option ensures compliance with local regulations.

Industry Applications
This probe is suited for radial vibration and position measurement on critical rotating machinery such as turbines, compressors, and pumps. The stainless steel case and PPS tip resist harsh process conditions.
Installation & Setup Guidance
For reliable operation, use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a 3-conductor shielded triad cable and tinned wiring. The maximum length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Ensure the probe thread engagement does not exceed 0.563 in for the 3/8-24 thread. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring.
Maintenance & Reliability
The probe operates reliably from -52°C to +177°C (-62°F to +350°F) for standard versions. Extended temperature range probes handle up to +218°C (+425°F) at the tip and +260°C (+500°F) at the cable and connector. Exposure to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. The probe shows less than 3% change in Average Scale Factor (ASF) when tested in 93% humidity per IEC 68-2-3 for up to 56 days.
Compatibility & Integration
The 330102-00-24-10-02-CN is designed for use with Bently Nevada 3300 XL Proximitor Sensors. When installed with intrinsically safe zener barriers per drawing 141092 or galvanic isolators, it is approved for 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 is approved for 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 llC T5…T1 Gc.
