Reliable Vibration Monitoring with the Bently Nevada 3300 XL Probe
Industrial rotating machinery demands precise, continuous vibration measurement to prevent catastrophic failures. The Bently Nevada 330103-00-12-10-02-00 is a 3300 XL 8 mm Proximity Probe designed for eddy current displacement sensing. This metric probe delivers accurate gap and vibration data for critical assets like turbines, compressors, and pumps.

Industry Applications for the 3300 XL Probe
Typical applications include:
- Steam and Gas Turbines: Radial vibration measurement using the recommended -9 Vdc gap setting ensures early detection of imbalance or misalignment.
- Centrifugal Compressors: The 2 mm linear range provides reliable data for surge protection and shaft orbit analysis.
Installation and Setup Guidance
Proper installation is critical for accurate readings. The probe uses an M10x1 thread with a maximum engagement length of 15 mm. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable. 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 to account for signal roll-off.
Maintenance and Reliability
The probe is designed for harsh environments. The PPS tip and stainless steel case resist corrosion and wear. Operating temperature range is -52°C to +177°C for standard probes. Humidity exposure below 93% RH causes less than 3% change in Average Scale Factor per IEC 68-2-3. Inspect the cable and connector periodically for damage. The probe is not pressure tested before shipment; contact the custom design department if pressure seal testing is required.
Compatibility and 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 I, 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 I, Division 2, Groups A, B, C, D.
Selection Guide and Purchasing Advice
When selecting a replacement or spare probe, verify the thread size (M10x1), overall case length (120 mm), and total cable length (1.0 m). The 330103-00-12-10-02-00 is available from AutoDCSTech. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
