Bently Nevada 330103-00-04-10-12-CN 3300 XL 8 mm Proximity Probe, Metric

Product Overview

The Bently Nevada 330103-00-04-10-12-CN is a 3300 XL 8 mm proximity probe designed for precise displacement and vibration measurements in critical rotating machinery. This metric probe features an M10 x 1 thread, a polyphenylene sulfide (PPS) tip, and a miniature coaxial ClickLoc connector with FluidLoc cable. It is suitable for applications requiring reliable, non-contact sensing in harsh industrial environments.

Technical Specifications Breakdown

Key parameters for the 330103-00-04-10-12-CN are listed below for quick reference:

Industry Applications

Its 2 mm linear range and -9 Vdc recommended gap setting enable accurate radial vibration measurement. The PPS tip and stainless steel case resist harsh process environments. Compared to standard eddy-current probes, the 3300 XL series offers enhanced temperature tolerance and intrinsic safety options, reducing downtime in refineries and power plants.

Installation & Setup Guidance

Mount the probe with M10 x 1 threads, ensuring maximum thread engagement of 15 mm. Use 0.2 to 1.5 mm² (16 to 24 AWG) field wiring with a 3-conductor shielded triad cable. Maximum cable length between the probe and monitor is 305 meters (1,000 feet). Set the gap to approximately 1.27 mm (50 mils) for radial vibration applications, corresponding to -9 Vdc output. Refer to frequency response graphs for signal rolloff at high frequencies with longer cables.

Maintenance & Reliability

Inspect the probe and cable periodically for physical damage or contamination. The probe is designed to seal differential pressure using a Viton® O-ring; avoid exposing to temperatures below -34°C (-30°F) to prevent premature seal failure. The standard probe operates from -52°C to +177°C, while extended range versions handle up to +218°C at the tip. Humidity testing shows less than 3% change in Average Scale Factor (ASF) after 56 days at 93% humidity.

Compatibility & Integration

The 330103-00-04-10-12-CN is compatible with Bently Nevada 3300 XL Proximitor sensors and monitoring systems. When used with intrinsic safety barriers (per drawing 141092) or galvanic isolators, it achieves Class I, Zone 0 approval. For non-incendive installations (per drawing 140979), it meets Class I, Zone 2 requirements. Always verify system compatibility and follow approved wiring diagrams.

Selection Guide & Purchasing Advice

When selecting a proximity probe, consider cable length, connector type, and temperature range. For extended temperature or different cable lengths, consult Bently Nevada options.
