Bently Nevada 330103-00-04-20-02-CN 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330103-00-04-20-02-CN are listed below for quick reference:

Industry Applications

Its 2 mm linear range and -9 Vdc recommended gap setting allow precise radial vibration measurement. The PPS tip and stainless steel case withstand high temperatures and corrosive atmospheres, making it suitable for oil and gas, power generation, and chemical processing plants. By integrating this probe into a condition monitoring system, operators can detect early bearing wear or shaft misalignment, reducing maintenance costs.

Installation & Setup Guidance

When installing the 330103-00-04-20-02-CN, ensure the probe case thread engagement does not exceed 15 mm. Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a 3-conductor shielded triad cable. The maximum field wiring length between the Proximitor Sensor and monitor is 305 meters (1,000 feet). For radial vibration applications, set the gap to -9 Vdc (approximately 1.27 mm or 50 mils) from the target surface. Verify the probe is not pressure tested prior to shipment; contact the custom design department if pressure seal testing is required.

Maintenance & Reliability

Inspect the probe cable and connector periodically for damage, especially in high-vibration environments. The probe is designed to seal differential pressure using a Viton O-ring. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The probe meets humidity standards with less than 3% change in Average Scale Factor when tested at 93% humidity per IEC 68-2-3 for up to 56 days. For extended temperature applications, ensure the probe tip does not exceed +218°C.

The Evolution of Precision Monitoring

Industrial machinery monitoring has shifted from reactive repairs to predictive maintenance. The Bently Nevada 330103-00-04-20-02-CN 3300 XL 8 mm Proximity Probe embodies this shift, offering engineers a reliable tool for measuring shaft vibration and position in rotating equipment. This probe is designed for harsh environments, providing consistent data to prevent unplanned downtime.

Compatibility & Integration

The 330103-00-04-20-02-CN is part of the 3300 XL series and works with Bently Nevada Proximitor Sensors and monitoring systems. When installed with intrinsically safe zener barriers per drawing 141092 or galvanic isolators, it achieves Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga ratings. For non-incendive circuits per drawing 140979, it meets Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc. Verify agency approval compatibility for your region.

Selection Guide & Purchasing Advice

Choose the 330103-00-04-20-02-CN for applications requiring a 2.0-meter cable with a miniature coaxial ClickLoc connector. The "CN" suffix indicates country-specific approvals.
