Bently Nevada 330103-00-17-10-02-CN 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330103-00-17-10-02-CN are listed below for quick reference:

Industry Applications: Protecting Rotating Assets

In oil and gas facilities, the PPS tip and stainless steel case resist corrosive atmospheres, while the extended temperature range option (-52°C to +218°C for the tip) suits high-heat environments like gas turbines. By catching bearing wear or imbalance early, the probe helps avoid catastrophic failures and unplanned downtime.

Installation and Setup Guidance

When field wiring the 330103-00-17-10-02-CN, use 0.2 to 1.5 mm² (16 to 24 AWG) conductor shielded triad cable with tinned ends. The maximum length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Ensure the probe tip is clean and the target surface is smooth and electrically conductive. For radial vibration, set the gap to -9 Vdc (approximately 1.27 mm or 50 mils) using a shim or micrometer. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure.

Evolution of Vibration Monitoring: Precision Meets Reliability

In the relentless march of industrial automation, the ability to detect subtle shifts in rotating machinery has transformed from a luxury to a necessity. Early vibration sensors were bulky and prone to drift, but modern eddy-current probes like the Bently Nevada 330103-00-17-10-02-CN deliver micron-level accuracy in extreme conditions. This 3300 XL 8 mm Proximity Probe represents decades of refinement, offering engineers a robust tool for safeguarding critical assets.

Maintenance and Reliability

Inspect the probe cable and connector periodically for wear or damage, especially in high-vibration areas. The probe is designed to seal differential pressure between tip and case using a Viton O-ring, but it is not pressure tested before shipment. For applications requiring pressure seal verification, contact the custom design department. The probe's relative humidity performance shows less than 3% change in Average Scale Factor (ASF) after 56 days at 93% humidity per IEC 68-2-3.

Compatibility and Integration

When installed with intrinsically safe zener barriers per drawing 141092 or galvanic isolators, it is rated 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 and AEx/Ex ec IIC T5…T1 Gc. Always follow the specific approval drawing for your installation.
