Product Overview

The 330902-00-30-05-02-05 is a specialized eddy current proximity transducer from the Bently Nevada 3300 NSv (Narrow Side View) series. This system is specifically engineered for applications where standard 8 mm probes cannot be used due to tight spatial constraints, such as small shaft diameters or limited side-view clearance. It provides non-contacting displacement measurements, converting the physical distance between the probe tip and a conductive target into a linear voltage signal. As a critical component of Turbine Supervisory Instrumentation (TSI), it is essential for monitoring radial vibration and axial position on centrifugal compressors, pumps, and other high-speed rotating assets.

Technical Configuration

The model 330902-00-30-05-02-05 is defined by the following technical parameters:

• Overall Case Length: 3.0 inches

• Total System Length: 0.5 Meters (approx. 1.6 feet)

• Connector Interface: Miniature coaxial ClickLoc connector (02 option)

• Agency Approvals: Multi-certified for hazardous areas including ATEX, IECEx, and CSA (05 option)

• Target Material: Calibrated for AISI 4140 steel

• Linear Measurement Range: 1.5 mm (60 mils)

Engineering and Durability Features

The 3300 NSv series incorporates advanced mechanical design features to ensure longevity in demanding industrial process environments:

• Narrow Side View Capability: Specifically designed to ignore surrounding conductive material, allowing for accurate measurements on shafts as small as 50 mm (2 inches) or in counterbores with minimal clearance.

• Stainless Steel Armor: The FEP-insulated coaxial lead is protected by flexible 304 stainless steel armor, preventing mechanical damage, abrasion, and accidental severing in complex machine internal housings.

• Improved RFI/EMI Immunity: Engineered to maintain signal integrity in environments with high electromagnetic interference, meeting European CE mark requirements without specialized shielded conduits.

• ClickLoc Connectivity: Features a corrosion-resistant, gold-plated miniature coaxial connector that provides a secure, vibration-proof electrical path.

System Compatibility and Installation

The 330902-00-30-05-02-05 is part of an integrated transducer system that offers superior flexibility:

• Interchangeability: Probes, extension cables, and 3300 NSv Proximitor sensors of the same system length are fully interchangeable without the need for manual recalibration.

• SpringLoc Terminals: When paired with the 3300 NSv Proximitor, wiring is simplified via tool-free spring-loaded terminals, reducing installation time and ensuring vibration-resistant connections.

• Industrial Applications: Optimized for fluid-film bearing machines where radial and axial clearances are restrictive, ensuring reliable machinery protection and condition monitoring.
