Product Overview

The 330102-00-28-05-02-00 is a high-performance armored proximity sensor within the Bently Nevada 3300 XL 8 mm transducer family. This eddy-current probe is designed for non-contacting displacement measurement, providing critical data for machinery protection systems. By measuring the physical gap between the probe tip and a conductive target—typically a rotating shaft—it allows for the precise monitoring of radial vibration, axial thrust position, and eccentricity. As a primary component of Turbine Supervisory Instrumentation (TSI), this 0.5-meter armored probe is built to maintain signal integrity in high-vibration and harsh industrial environments.

Technical Configuration

• Agency Approval: Standard (00 option - no specific hazardous area certifications)

• Linear Range: 2.0 mm (80 mils)

• Scale Factor: 7.87 V/mm (200 mV/mil) when used with a 3300 XL Proximitor

Robust Mechanical Construction

Bently Nevada has engineered the 330102-00-28-05-02-00 with several proprietary technologies to ensure longevity and reliability on critical assets:

• Armored Lead Protection: The FEP-insulated coaxial cable is encased in flexible stainless steel armor, shielding the signal path from mechanical abrasion and accidental cutting.

• TipLoc Molding: A specialized manufacturing process creates a molecular-level bond between the PPS (polyphenylene sulfide) plastic probe tip and the stainless steel body, preventing moisture ingress and tip delamination.

• CableLoc Anchoring: The internal cable connection is designed to withstand a pull strength of up to 330 N (75 lbf), protecting the sensor from installation-related strain.

• Gold-Plated Connectivity: The Click-Lok connector provides a vibration-resistant electrical interface that is easy to engage and disengage without specialized tools.

Industrial Applications and System Compatibility

This transducer is a foundational element for comprehensive machinery health monitoring:

• Universal Compatibility: Fully interchangeable with other 3300 XL system components of the same length; probes, cables, and sensors can be replaced without manual bench calibration.

• Backward Compatibility: Electrically and physically compatible with older non-XL 3300 series 5 mm and 8 mm proximity systems.

• Asset Protection: Essential for the monitoring of fluid-film bearing machines, including steam and gas turbines, centrifugal compressors, and high-pressure pumps.

• Target Material: Factory-calibrated for AISI 4140 steel, maintaining high accuracy across a broad frequency response range.
