Bently Nevada 330103-00-08-10-01-00 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330103-00-08-10-01-00 are listed below for quick reference:

Industry Applications

Rotating machinery failure often begins with undetected shaft vibration. The Bently Nevada 330103-00-08-10-01-00 3300 XL 8 mm Proximity Probe provides precise, non-contact displacement measurement to prevent costly unplanned downtime. This probe is engineered for continuous operation in harsh industrial environments, offering a linear range of 2 mm (80 mils) starting at approximately 0.25 mm (10 mils) from the target. With a recommended gap setting of -9 Vdc for radial vibration, it delivers reliable data for predictive maintenance strategies.

Installation & Setup Guidance

Proper installation is critical for accurate readings. The probe case thread M10 x 1 allows a maximum thread engagement of 15 mm. Use 3-conductor shielded triad cable with tinned field wiring (0.2 to 1.5 mm² / 16 to 24 AWG). The maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Ensure the probe tip is clean and free from debris before mounting. The probe is designed to seal differential pressure between tip and case using a Viton O-ring; avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure.

Maintenance & Reliability

Routine inspection of the probe and cable assembly is recommended. Check for physical damage, especially at the connector and cable entry points. The probe case is made of AISI 303 or 304 stainless steel, offering corrosion resistance in most industrial atmospheres. The PPS tip withstands standard operating temperatures from -52°C to +177°C. For extended temperature applications, the probe tip can handle up to +218°C. Humidity testing shows less than 3% change in Average Scale Factor after 56 days at 93% humidity, ensuring stable performance in wet environments.

Compatibility & Integration

This 3300 XL 8 mm probe is designed for use with Bently Nevada 3300 XL Proximitor Sensors and monitoring systems. When installed with intrinsically safe zener barriers per drawing 141092 or galvanic isolators, it is suitable for Class I, Zone 0 hazardous areas (AEx/Ex ia IIC T5...T1 Ga). For non-incendive installations per drawing 140979, it meets Class I, Zone 2 requirements (AEx/Ex nA IIC T5…T1 Gc). Always verify system compatibility before installation.

Selection Guide & Purchasing Advice

Choosing the correct probe configuration is essential for reliable vibration monitoring. The 330103-00-08-10-01-00 features an unthreaded length of 0 mm, an overall case length of 80 mm, a total length of 1.0 meter, and a miniature coaxial ClickLoc connector.
