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

Technical Specifications Breakdown

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

Industry Applications for the 3300 XL Probe

Its 2 mm linear range and -9 Vdc recommended gap setting provide reliable shaft vibration and position data. The CSA, ATEX, and IECEx approvals allow installation in hazardous areas, such as oil and gas facilities or chemical plants, where intrinsic safety is critical. The PPS tip and stainless steel case resist moisture and mild chemicals, ensuring long service life.

Installation and Setup Guidance

Proper installation is essential for accurate readings. The M10 x 1 thread allows a maximum thread engagement of 15 mm. Use a 3-conductor shielded triad cable (16 to 24 AWG) for field wiring, with a maximum length of 305 meters (1,000 feet) between the probe and the monitor. Ensure the probe tip is clean and the target surface is smooth. The recommended gap setting of -9 Vdc corresponds to approximately 1.27 mm (50 mils) from the target. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure.

Maintenance and Reliability

Regularly inspect the probe cable and connector for damage, especially in high-vibration environments. The FluidLoc cable resists moisture, but periodic checks for wear are advised. The probe operates reliably in up to 93% relative humidity with less than 3% change in Average Scale Factor (ASF). For extended temperature applications, the probe tip can withstand up to +218°C (+425°F), while the cable handles up to +260°C (+500°F).

Selecting the Right Vibration Probe for Critical Machinery

When monitoring rotating machinery, the choice of proximity probe directly impacts measurement accuracy and system reliability. The Bently Nevada 330103-05-10-10-12-05 is a 3300 XL 8 mm proximity probe designed for precise displacement measurements in harsh industrial environments. This model features an M10 x 1 thread, a 50 mm unthreaded length, and a 100 mm overall case length, making it suitable for installations requiring a compact yet robust sensing element.

Compatibility and Integration

The 330103-05-10-10-12-05 integrates with Bently Nevada 3300 XL Proximitor sensors and monitoring systems. When used with intrinsic safety barriers per drawing 141092 or galvanic isolators, it meets Class I, Zone 0 requirements (AEx/Ex ia IIC T5...T1 Ga). For non-incendive installations per drawing 140979, it qualifies for Class I, Zone 2 (AEx/Ex nA IIC T5…T1 Gc).

Selection Guide and Purchasing Advice

When selecting a replacement probe, verify the thread size (M10 x 1), total length (1.0 meter), and agency approvals (CSA, ATEX, IECEx) match your system requirements. The 330103-05-10-10-12-05 is a standard probe without armor, suitable for most industrial applications. For pressure-sealed applications, note that probes are not pressure tested before shipment.
