Bently Nevada 330103-00-06-05-12-05 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330103-00-06-05-12-05 are listed below for quick reference:

Industry Applications

Its 2 mm linear range and -9 Vdc recommended gap setting enable precise radial vibration and thrust position monitoring. The CSA, ATEX, and IECEx approvals allow installation in hazardous areas (Class I, Zone 0) when paired with intrinsic safety barriers or galvanic isolators per Bently Nevada drawing 141092. For non-incendive installations, the probe supports Class I, Zone 2 per drawing 140979. By choosing this probe, you reduce unplanned downtime and extend machinery life through early fault detection.

Installation & Setup Guidance

For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned ends. The maximum cable 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 free of scratches. The maximum thread engagement length is 15 mm; do not exceed this to avoid damaging the probe case. When setting the gap, target -9 Vdc (approximately 1.25 mm or 50 mils) for radial vibration measurements. Always consult the frequency response graphs for signal roll-off at high frequencies when using longer cable runs.

Maintenance & Reliability

The probe’s PPS tip and stainless steel case resist corrosion and wear. The pressure seal, using a Viton O-ring, maintains differential pressure between tip and case. Exposing the probe to temperatures below -34°C (-30°F) may cause premature seal failure. The probe shows less than 3% change in Average Scale Factor (ASF) when tested in 93% humidity per IEC 68-2-3 for up to 56 days. Inspect the cable and connector periodically for damage, and verify the probe resistance (7.45 ± 0.50 Ω) during routine checks.

Precision Vibration Monitoring with the Bently Nevada 330103-00-06-05-12-05

When your rotating machinery demands accurate and reliable shaft vibration and position measurements, the Bently Nevada 330103-00-06-05-12-05 3300 XL 8 mm Proximity Probe delivers the performance you need. This metric probe, featuring an M10 x 1 thread and a robust polyphenylene sulfide (PPS) tip, is engineered for harsh industrial environments. With a 0.5 meter (1.6 feet) total length and a miniature coaxial ClickLoc connector with FluidLoc cable, it simplifies installation while ensuring signal integrity.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, confirm your system’s thread size (M10 x 1), cable length, and connector type. The 330103-00-06-05-12-05 is a standard probe without armor, suitable for most industrial applications. For extended temperature ranges (probe tip up to +218°C, cable up to +260°C), consider the extended range variant.
