Bently Nevada 330103-00-03-10-12-05 3300 XL 8 mm Proximity Probe

Product Overview

The Bently Nevada 330103-00-03-10-12-05 is a 3300 XL 8 mm Proximity Probe designed for precise, non-contact vibration and position measurement in critical rotating machinery. This probe features an M10 x 1 thread, a 30 mm overall case length, and a 1.0 meter (3.3 feet) total length with a miniature coaxial ClickLoc connector and FluidLoc cable. With CSA, ATEX, and IECEx approvals, it is suitable for hazardous area installations. The probe tip is made of Polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel, ensuring durability in harsh environments.

Technical Specifications Breakdown

Key parameters for the 330103-00-03-10-12-05 are listed below for quick reference:

Industry Applications

This proximity probe is commonly used for radial vibration and thrust position monitoring in steam turbines, compressors, pumps, and other rotating equipment. The 2 mm linear range and -9 Vdc recommended gap setting provide consistent performance for machinery protection systems. Its hazardous area approvals (CSA, ATEX, IECEx) make it suitable for oil and gas, petrochemical, and power generation environments where safety is critical.

Installation & Setup Guidance

When installing the 330103-00-03-10-12-05, ensure the probe tip is clean and free of debris. The maximum thread engagement for the M10x1 thread is 15 mm. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned wiring. The maximum length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Refer to the frequency response graphs for signal rolloff at high frequencies when using longer wiring.

Maintenance & Reliability

Regularly inspect the probe cable and connector for damage. Avoid exposing the probe to temperatures below –34°C (–30°F) to prevent premature failure of the pressure seal. The Viton® O-ring seal is designed for differential pressure between tip and case; contact the custom design department if pressure testing is required. The probe is not pressure tested prior to shipment.

Compatibility & Integration

This probe is part of the 3300 XL series and is compatible with Bently Nevada 3300 XL Proximitor Sensors and monitoring systems. When installed with intrinsically safe zener barriers per drawing 141092 or galvanic isolators, it meets Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga requirements. For non-incendive installations, use drawing 140979 to achieve Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, verify the total length, connector type, and agency approvals match your system requirements. The 330103-00-03-10-12-05 is available from AutoDCSTech, a trusted supplier of industrial automation parts. Please verify current lifecycle status and availability with AutoDCSTech before ordering.

Troubleshooting & Common Issues

If readings are erratic, check the probe tip for contamination or damage. Verify the gap setting is within the linear range (0.25 to 2.3 mm). Ensure the cable is not kinked or pinched. For signal noise issues, confirm proper shielding and grounding of the field wiring. If the pressure seal fails, contact the custom design department for testing options.
