Bently Nevada 330103-00-04-10-01-00 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330103-00-04-10-01-00 are listed below for quick reference:

Industry Applications

Turbine Shaft Monitoring

In steam and gas turbines, the 330103-00-04-10-01-00 provides precise radial vibration and thrust position measurements. Its 2 mm linear range and -9 Vdc recommended gap setting ensure accurate data for predictive maintenance programs.

Compressor Protection

Centrifugal and axial compressors benefit from the probe's robust stainless steel construction and wide temperature range (-52°C to +177°C). The PPS tip resists chemical exposure, making it suitable for oil and gas environments.

Pump Health Assessment

For critical pumps in refineries or water treatment, this proximity probe detects shaft misalignment and bearing wear early. The miniature ClickLoc connector simplifies installation in tight spaces.

Installation and Setup Guidance

Proper installation is critical for reliable measurements. Mount the probe with M10x1 thread, ensuring the maximum thread engagement of 15 mm is not exceeded. Use 3-conductor shielded triad cable with 0.2 to 1.5 mm² (16 to 24 AWG) tinned field wiring. The maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Set the initial gap to -9 Vdc (approximately 1.27 mm or 50 mils) for radial vibration applications. Refer to the frequency response graphs (Figures 10 and 12) for signal rolloff at high frequencies when using longer cable runs.

Maintenance and Reliability

Inspect the probe and cable periodically for physical damage or contamination. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring. For applications requiring pressure testing, 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.

Precision Vibration Monitoring with the Bently Nevada 330103-00-04-10-01-00

Industrial rotating machinery demands accurate, reliable vibration measurement to prevent catastrophic failures. The Bently Nevada 330103-00-04-10-01-00 is a 3300 XL 8 mm Proximity Probe designed for non-contact displacement sensing in critical applications such as turbines, compressors, and pumps. This metric probe offers a robust solution for monitoring shaft vibration and position, helping you reduce unplanned downtime and extend equipment life.

Key Features and Design

This probe features a polyphenylene sulfide (PPS) tip and an AISI 303 or 304 stainless steel case, ensuring durability in harsh environments. The M10x1 thread allows secure installation, while the 40 mm overall case length and 1.0 meter (3.3 feet) total length provide flexibility for various mounting configurations. The miniature coaxial ClickLoc connector with connector protector simplifies field wiring and maintains signal integrity.

Compatibility and Integration

This probe is part of the 3300 XL series and works with compatible Bently Nevada Proximitor Sensors and monitoring systems. For intrinsically safe installations, use zener barriers per drawing 141092 or galvanic isolators to achieve Class I, Zone 0 ratings (AEx/Ex ia IIC T5...T1 Ga). For non-incendive circuits, follow drawing 140979 for Class I, Zone 2 (AEx/Ex nA IIC T5…T1 Gc). Always verify system compatibility before ordering.

Selection Guide and Purchasing Advice

When selecting the 330103-00-04-10-01-00, confirm your required thread size (M10x1), cable length (1.0 m), and connector type (miniature coaxial ClickLoc). This model does not include armor or agency approval. For alternative configurations, explore other 3300 XL probe options.
