Product Overview

The 330101-00-35-05-02-05 is a high-precision eddy current proximity probe from the Bently Nevada 3300 XL series. This 8 mm sensor is engineered for non-contacting displacement sensing, converting the physical distance between the probe tip and a conductive target into a linear voltage signal. As a vital component for Turbine Supervisory Instrumentation (TSI), it provides the high-fidelity data required to monitor radial vibration, axial thrust, and eccentricity in critical rotating machinery. This specific configuration features a 3/8-24 UNF threaded body and a 0.5-meter total length, optimized for localized machine mounting where space or specific cable routing is a priority.

Technical Configuration

Enhanced Mechanical Design

This 3300 XL probe incorporates patented manufacturing technologies to ensure long-term stability in extreme industrial environments:

• TipLoc Technology: A proprietary molding process creates a molecular bond between the probe tip and the stainless steel body, ensuring a vacuum-tight seal that prevents fluid wicking and tip delamination.

• CableLoc Design: An internal anchoring system provides 330 N (75 lbf) of pull strength, shielding the electrical junction from mechanical strain during installation or operation.

• Gold-Plated ClickLoc: The probe utilizes a corrosion-resistant, gold-plated miniature coaxial connector that provides an audible "click" when securely locked, ensuring a vibration-resistant connection without tools.

• RFI/EMI Immunity: Advanced circuitry meets European CE standards for electromagnetic interference, allowing for reliable operation near high-frequency noise sources without specialized shielded conduits.

System Compatibility and Application

The 330101-00-35-05-02-05 is designed for seamless inclusion in modern machinery protection strategies:

• Full Interchangeability: Components within the 3300 XL system are fully interchangeable; probes, cables, and Proximitor sensors can be swapped without manual bench calibration.

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

• TSI Monitoring: Ideal for measuring shaft vibration in fluid-film bearing machines, including steam turbines, compressors, and high-speed pumps.

• Target Calibration: Factory-calibrated for AISI 4140 steel targets with a standard scale factor of 7.87 V/mm (200 mV/mil).
