Bently Nevada 330103-00-05-15-01-00 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330103-00-05-15-01-00 are listed below for quick reference:

Industry Applications for Vibration Monitoring

The 2 mm linear range (0.25 to 2.3 mm from target) provides precise data for predictive maintenance. In a consulting role, we often recommend this probe for applications requiring high-temperature resistance up to +177°C (standard) or +218°C (extended range) for the probe tip. The robust stainless steel case and PPS tip withstand oil, moisture, and particulate contamination common in industrial environments.

Installation Guidance for Engineers

Proper installation is critical for accurate readings. The probe case thread is M10 x 1 with a maximum thread engagement of 15 mm. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned wiring. The maximum length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). For radial vibration, set the gap to -9 Vdc (approximately 1.27 mm or 50 mils). Ensure the probe is not exposed to temperatures below -34°C (-30°F) to avoid premature pressure seal failure.

Maintenance and Reliability Considerations

The probe is designed to seal differential pressure between the tip and case using a Viton O-ring. It is not pressure tested before shipment. For long-term reliability, inspect the cable and connector periodically for damage. The probe operates in humidity up to 93% with less than 3% change in Average Scale Factor (ASF) per IEC 68-2-3. When installed with intrinsic safety barriers per drawing 141092 or galvanic isolators, it meets Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga. For non-incendive circuits per drawing 140979, it meets Class I, Zone 2: AEx/Ex nA IIC T5...T1 Gc.

Selecting the Right Proximity Probe for Critical Machinery

When monitoring rotating machinery, the transducer is the first link in the measurement chain. The Bently Nevada 330103-00-05-15-01-00 is a 3300 XL 8 mm Proximity Probe designed for reliable shaft vibration and position measurements. This metric probe features an M10 x 1 thread, a 50 mm overall case length, and a 1.5 meter (4.9 feet) total length with a miniature coaxial ClickLoc connector and connector protector. The probe tip is made of polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel, ensuring durability in harsh environments.
