Product Overview

The Bently Nevada 330102-27-46-10-02-05 is an 8 mm eddy-current proximity probe used for non-contact measurement of relative shaft displacement. When installed with the correct gap to a conductive target, the probe senses changes in distance and supports both static position (gap) and dynamic vibration measurements as part of a complete 3300 XL proximity transducer channel (probe + extension cable + Proximitor sensor).

This probe configuration is typically applied on fluid-film bearing machines where continuous monitoring is required for machinery protection and condition-based maintenance. Output scaling and channel performance depend on the associated Proximitor sensor, extension cable length class, and the target material commonly referenced as AISI 4140 steel for standard calibration practice.

Key Technical Characteristics

• Model / Order Number: 330102-27-46-10-02-05

• Series / Platform: 3300 XL 8 mm proximity transducer components

• Sensing Principle: Eddy-current displacement measurement (non-contact)

• Channel Use: Works with matching 3300 XL extension cable and Proximitor sensor

• Typical Channel Scaling: 100 mV/mil (3.94 V/mm) with correct system components and target material

• Mechanical Features (as referenced): TipLoc tip-to-body retention and CableLoc pull-strength design concepts

• Interchangeability: Intended interchangeability within the same 3300 XL system length class; backward compatibility with legacy 3300 5 mm/8 mm installations may be achievable depending on system design and cable routing constraints

• Compliance Reference: API 670 requirements are commonly associated with 3300 XL proximity systems when configured correctly

Logistics and commercial data

Installation notes

• Maintain rigid mounting and correct probe gap to prevent measurement drift and false vibration indications.

• For wet or oil-exposed locations, specify appropriate sealed cable options if the installation requires fluid ingress resistance.

Industrial Applications

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

• Shaft position and displacement trending for sleeve-bearing machinery (monitor dependent)

• Phase reference or speed-related channels when used in a dedicated probe configuration and compatible monitor logic

• Reliability programs requiring repeatable proximity measurements for diagnostics and predictive maintenance
