Struggling with unreliable vibration readings on your critical rotating machinery? The Bently Nevada 330103-00-03-05-02-05 3300 XL 8 mm Proximity Probe delivers the precision and durability you need for accurate shaft displacement and eccentricity monitoring. This metric probe, part of the trusted 3300 XL series, is engineered for harsh industrial environments.
Product Overview
The 330103-00-03-05-02-05 is a 3300 XL 8 mm proximity probe from Bently Nevada. It features an M10 x 1 thread, a 0 mm unthreaded length, a 30 mm overall case length, and a 0.5 meter (1.6 feet) total length. The probe uses a miniature coaxial ClickLoc connector with standard cable and carries CSA, ATEX, and IECEx approvals. Its tip is made of polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel (SST). This probe is designed to seal differential pressure between the tip and case using a Viton O-ring.

Industry Applications
Its CSA, ATEX, and IECEx approvals allow installation in hazardous areas, reducing downtime and maintenance costs.
Installation & Setup Guidance
Mount the probe with M10 x 1 threads, ensuring maximum thread engagement of 15 mm. Use 3-conductor shielded triad cable with tinned field wiring (0.2 to 1.5 mm² or 16 to 24 AWG). The maximum field wiring length to the 3300 XL Proximitor Sensor is 305 meters (1,000 feet). Set the gap to approximately -9 Vdc (1.27 mm) for radial vibration monitoring. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure.
Maintenance & Reliability
Inspect the probe and cable periodically for physical damage or wear. The PPS tip and stainless steel case resist corrosion and mechanical stress. The Viton O-ring maintains pressure sealing, but the probe is not pressure tested before shipment. Contact AutoDCSTech if pressure seal testing is required. The probe operates reliably in up to 93% humidity with less than 3% change in Average Scale Factor (ASF).
Compatibility & Integration
The 330103-00-03-05-02-05 is compatible with Bently Nevada 3300 XL Proximitor Sensors and monitoring systems. It supports intrinsic safety when installed with zener barriers per drawing 141092 or galvanic isolators (Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga). For non-incendive installations, use drawing 140979 (Class I, Zone 2: AEx/Ex nA IIC T5...T1 Gc).
Selection Guide & Purchasing Advice
When selecting a proximity probe, verify the thread size, cable length, and agency approvals match your application. The 330103-00-03-05-02-05 offers a 0.5 meter cable and metric M10 x 1 thread. For longer cable lengths or different connector options, contact AutoDCSTech. Our team can help you find the exact Bently Nevada part for your machinery monitoring needs. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
