Industry Applications for the 3300 XL Probe

The 330103-00-09-10-02-CN is designed for critical machinery monitoring in industries such as oil and gas, power generation, and petrochemical processing. Typical applications include:

• Turbomachinery Protection: Measuring radial vibration and axial position of steam turbines, gas turbines, and compressors. The 2 mm linear range and -9 Vdc recommended gap provide stable, repeatable readings for early fault detection.
• Pump and Motor Monitoring: Detecting shaft displacement in large centrifugal pumps and electric motors. The stainless steel case and PPS tip resist process fluids and high temperatures up to +177°C.
• Hydroelectric Generators: Monitoring thrust bearing wear and shaft runout. The probe's 1.0 meter cable length simplifies routing to the Proximitor sensor.

Installation & Setup Guidance

Proper installation is critical for accurate measurement. Follow these guidelines based on the probe specifications:

• Mounting: Use the M10 x 1 thread with maximum thread engagement of 15 mm. Ensure the probe tip is clean and free of debris before insertion.
• Field Wiring: Connect using 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned ends. Maximum cable length between probe and monitor is 305 meters (1,000 feet).
• Gap Setting: For radial vibration applications, set the initial gap to achieve approximately -9 Vdc output, corresponding to about 1.27 mm (50 mils) from the target.
• Pressure Seal: The Viton® O-ring provides differential pressure sealing. The probe is not pressure tested before shipment; contact the custom design department if testing is required.

Maintenance & Reliability

To ensure long service life, inspect the probe cable and connector periodically for damage. The probe operates reliably in humidity up to 93% with less than 3% change in Average Scale Factor (ASF) per IEC 68-2-3. Avoid exposing the probe to temperatures below -34°C (-30°F) as this may cause premature failure of the pressure seal. For extended temperature range applications, the probe tip can withstand up to +218°C (+425°F) and the cable up to +260°C (+500°F).

Precision Vibration Monitoring with the 330103-00-09-10-02-CN

Industrial rotating machinery demands reliable, accurate displacement measurement to prevent catastrophic failures. The Bently Nevada 330103-00-09-10-02-CN 3300 XL 8 mm Proximity Probe delivers the proven performance and rugged construction required for continuous protection in harsh environments. This component is engineered for direct connection to 3300 XL Proximitor sensors, forming a complete measurement chain for radial vibration and position monitoring.

Compatibility & Integration

The 330103-00-09-10-02-CN is part of the 3300 XL system and is compatible with 3300 XL Proximitor sensors. For intrinsically safe installations, use with approved zener barriers per drawing 141092 or galvanic isolators for Class I, Zone 0 (AEx/Ex ia IIC T5...T1 Ga) and Class I, Groups A-D, Class II, Groups E-G, Class III. For non-incendive circuits per drawing 140979, it is suitable for Class I, Zone 2 (AEx/Ex nA IIC T5…T1 Gc) and Class I, Division 2, Groups A-D.

Selection Guide & Purchasing Advice

When selecting a replacement or spare probe, verify the total length, thread size, and connector type match your existing installation. The 330103-00-09-10-02-CN offers a 1.0 meter cable with ClickLoc connector for secure, quick installation. For assistance with configuration or to confirm lifecycle status, contact AutoDCSTech.
