Product Overview

The Bently Nevada 330101-00-55-05-02-05 is a 3300 XL 8 mm eddy-current proximity probe used for non-contact measurement of relative shaft displacement. Installed near a conductive target, the probe detects small changes in shaft-to-probe gap and supports machinery protection and condition monitoring functions such as radial vibration and shaft position trending when used as part of a complete 3300 XL proximity transducer channel.

This part number represents a specific mechanical and cable configuration within the 3300 XL family. For correct scaling, linearity, and temperature stability, the probe must be paired with a compatible 3300 XL extension cable and the matching Proximitor sensor for the required total system length.

Important correction to listing inconsistencies

• Proximity probes are not powered by “-24 VDC” directly; the probe is a passive element. Powering and output behavior are determined by the Proximitor sensor and the receiving monitor.

• “80 mV/mil” is not the standard 3300 XL channel scaling; typical 3300 XL proximity systems use 100 mV/mil when configured with the correct components and target material.

Hardware Parameters

Commissioning notes

• Final performance depends on target material, mounting stiffness, probe gap setting, and correct cable routing/grounding practices.

• Use matching 3300 XL extension cable and Proximitor sensor for the specified system length to maintain the intended calibration.

Industrial Applications

• Radial shaft vibration monitoring on turbines, compressors, pumps, motors, and generators with sleeve bearings

• Shaft position and displacement trending for protection logic and diagnostics (monitor dependent)

• Retrofit replacement in existing 3300 XL installations requiring 3/8-24 UNF mounting and a short integral lead

• Installations in hazardous or regulated areas where certified components are required (verify nameplate approvals on the supplied unit)
