Bently Nevada 330103-00-03-10-01-00 3300 XL 8 mm Proximity Probe

Product Overview

This Bently Nevada 3300 XL 8 mm Proximity Probe is a non-contact sensor that measures radial vibration and axial position of rotating shafts. The part number 330103-00-03-10-01-00 decodes as: 3300 XL 8 mm probe with M10 x 1 thread, no armor, 0 mm unthreaded length, 30 mm overall case length, 1.0 meter (3.3 feet) total length, miniature coaxial ClickLoc connector with connector protector and standard cable, and no agency approval option. The probe tip is made of polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel (SST).

Technical Specifications Breakdown

Key parameters for the 330103-00-03-10-01-00 are listed below for quick reference:

Industry Applications

Its 2 mm linear range and robust PPS tip make it suitable for high-speed rotating equipment where precise shaft clearance measurements prevent catastrophic failures. The M10x1 thread allows direct mounting in standard bearing housings.

Installation & Setup Guidance

When installing, ensure the probe case thread engagement does not exceed 15 mm maximum. Use the recommended torque values: 11.2 N•m (100 in•lbf) for standard forward mounted probes, and 7.5 N•m (66 in•lbf) for the first three threads. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable. Maximum cable length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet).

Maintenance & Reliability

Inspect the probe and cable periodically for physical damage. The probe operates reliably from -52°C to +177°C (-62°F to +350°F) for standard range, with extended temperature options available for the tip up to +218°C (+425°F). Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. Humidity testing shows less than 3% change in Average Scale Factor (ASF) after 56 days at 93% humidity per IEC 68 2 3.

The Evolution of Precision Vibration Monitoring

In the demanding world of rotating machinery protection, the ability to capture accurate shaft displacement data has transformed maintenance strategies. The Bently Nevada 3300 XL series represents a milestone in eddy current probe technology, offering engineers a reliable window into machine health. The 330103-00-03-10-01-00 is a key component in this legacy, designed for critical applications where measurement certainty is non-negotiable.

Compatibility & Integration

The 330103-00-03-10-01-00 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 achieves hazardous area ratings: Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga; Class 1, Groups A, B, C, and D; Class II, Groups E, F, and G; Class III. For non-incendive installations per drawing 140979, it meets Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc and Class 1, Division 2 ratings.

Selection Guide & Purchasing Advice

Choose this probe for applications requiring a 1.0 meter cable length and standard PPS tip. For longer cable runs or armored versions, consult the full 3300 XL series.
