Bently Nevada 330103-00-06-10-02-00 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330103-00-06-10-02-00 are listed below for quick reference:

Industry Applications for Reliable Vibration Monitoring

Turbomachinery Protection

In steam turbines and gas compressors, the 330103-00-06-10-02-00 provides accurate shaft displacement data. The PPS tip withstands high temperatures up to +177°C, while the stainless steel case resists corrosion from lubricants and process fluids. This probe helps operators detect early signs of imbalance or misalignment.

Pump and Motor Monitoring

For centrifugal pumps and large electric motors, the 2 mm linear range covers typical vibration amplitudes. The miniature coaxial ClickLoc connector simplifies field wiring, reducing installation time. The probe's DC resistance of 7.59 ± 0.50 Ω ensures consistent signal transmission over the 1.0 meter cable.

Installation and Setup Guidance

Proper installation begins with selecting the correct thread engagement. The maximum thread engagement length for the M10 x 1 thread is 15 mm. Use a 3-conductor shielded triad cable with tinned field wiring for the field wiring between the Proximitor Sensor and the monitor. The maximum field wiring length is 305 meters (1,000 feet). Ensure the probe tip is clean and free of debris before insertion. The probe weight is 323 g/m (11.4 oz).

Maintenance and Reliability

Inspect the probe and cable periodically for physical damage or wear. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring. Avoid exposing the probe to temperatures below -34°C (-30°F), as this may cause premature failure of the pressure seal. The probe's Average Scale Factor changes less than 3% when tested in 93% humidity per IEC 68-2-3 for up to 56 days.

Optimizing Rotating Machinery Protection with the Bently Nevada 330103-00-06-10-02-00

When monitoring critical rotating assets, selecting the right proximity probe is essential for reliable vibration and position data. The Bently Nevada 330103-00-06-10-02-00 is a 3300 XL 8 mm Proximity Probe designed for precise shaft measurement in demanding industrial environments. This metric probe features an M10 x 1 thread, a 60 mm overall case length, and a 1.0 meter cable with a miniature coaxial ClickLoc connector. The probe tip is made of polyphenylene sulfide (PPS), and the case is constructed from AISI 303 or 304 stainless steel, ensuring durability and chemical resistance.

Addressing Common Measurement Challenges

Engineers often face signal degradation due to improper probe selection or installation. The 330103-00-06-10-02-00 addresses this with a linear range of 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target. The recommended gap setting for radial vibration is -9 Vdc, corresponding to about 1.27 mm (50 mils). This configuration provides stable output across the measurement span, reducing the risk of false trips or missed faults.

Compatibility and Integration

This probe is part of the Bently Nevada 3300 XL series and is compatible with 3300 XL Proximitor Sensors. When installed with intrinsically safe zener barriers per drawing 141092 or galvanic isolators, the probe can be used in hazardous locations: Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga; Class 1, Groups A, B, C, D; Class II, Groups E, F, G; Class III. For non-incendive installations per drawing 140979, it meets Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc; Class 1, Division 2, Groups A, B, C, D; and AEx/Ex ec IIC T5…T1 Gc.

Selection Guide and Purchasing Advice
