Description
The Bently Nevada 330102-20-55-10-02-00 is a 3300 XL 8 mm eddy current proximity probe used for monitoring dynamic vibration, axial position, and speed on fluid-film bearing machinery. During a recent turbine overhaul, our technical crew deployed this specific configuration on a high-pressure backup pump because its hardware profile provides precise linear tracking without requiring individual bench calibration.

Field Installation and Mechanical Guidelines
How do you guarantee a clean signal when mounting this probe inside a congested bearing housing? In field deployments, we discovered that maintaining the precise thread depth prevents structural damage to the target area during initial machine startup. Well, technically this unit features a scale factor of 200 mV/mil, but only if the target material matches standard AISI 4140 steel—though your actual calibration curve will drift slightly if you encounter non-standard shaft plating.
[3300 XL 8mm Probe Tip] ---> [1.0m Coaxial Cable] ---> [ClickLoc Joint] ---> [3300 XL Extension Cable] Don’t underestimate the physical limitations of the miniature coaxial connection. Over-tightening the ClickLoc joint past finger-tight strips the gold-plated threading; we advise tightening it finger-tight and applying a maximum of 0.565 N·m of torque using specialized connector tools. Additionally, verify that the unthreaded length choice allows at least 0.8 inches of thread clearance inside your mounting bracket to prevent casing deformation during high-vibration sweeps.
International Logistics and Trade Compliance FAQ
What specific customs data is declared for cross-border air freight?
Every outbound international shipment includes commercial invoices listing the standard HS Code 90319000 (parts for measuring or checking instruments), a detailed packing list highlighting net mass in kg, and safe-handling documentation. If your facility requires customized customs declarations or localized compliance paperwork, flag this prior to carrier pickup.
How is the integrated coaxial cable protected against rough handling during transit?
We isolate the probe body and its integrated 1.0-meter cable within static-dissipative heavy-gauge packaging, preventing tight bends below the minimum 25.4 mm bend radius limit. The inner container is then nested within shock-absorbent structural foam before being boxed for international transit.
