Industry Applications
This proximity probe is engineered for critical rotating machinery such as turbines, compressors, and pumps. In the power generation sector, it provides reliable shaft vibration data for early fault detection, reducing unplanned outages. In oil and gas, its robust PPS tip and stainless steel case withstand harsh environments, ensuring consistent performance. The 5-meter cable length is specifically designed for use with the 5 meter Proximitor sensor, simplifying system integration.

Installation & Setup Guidance
Proper installation is vital for accurate measurements. The probe case thread is M10 x 1 with a maximum thread engagement of 15 mm. Use the recommended torque values: 11.2 N·m (100 in·lbf) for standard forward mounted probes, and 7.5 N·m (66 in·lbf) for the first three threads. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable. The maximum length between the Proximitor sensor and monitor is 305 meters (1,000 feet). Always verify the recommended gap setting of -9 Vdc for radial vibration applications.
Maintenance & Reliability
Regular inspection of the probe and cable is recommended to ensure measurement integrity. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring. Note that exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. The probe exhibits less than a 3% change in Average Scale Factor (ASF) when tested in 93% humidity per IEC standard 68 2 3 for up to 56 days, demonstrating moisture resistance.
Evolution of Precision Monitoring
Industrial machinery monitoring has evolved from periodic manual checks to continuous, real-time data acquisition. The Bently Nevada 330103-00-04-50-11-00 represents a critical component in this evolution, enabling precise shaft vibration and position measurements in rotating equipment. As plants push for higher uptime and predictive maintenance, the reliability of each sensor becomes paramount. This 3300 XL 8 mm proximity probe delivers the accuracy and durability needed for demanding environments.

Compatibility & Integration
This probe is part of the 3300 XL series and is intended for use with the 5 meter Proximitor sensor. When installed with intrinsically safe zener barriers per drawing 141092 or with galvanic isolators, it is suitable for Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga; Class 1, Groups A, B, C, and D; Class II, Groups E, F, and G; Class III. For non-incendive installations 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
