3300 XL 8mm Proximity Sensor Probe 330101-40-60-05-02-05 by Bently Nevada

Product Overview

The Bently Nevada 330101-40-60-05-02-05 is an industrial-grade, 8mm eddy current proximity probe designed for continuous condition monitoring of critical rotating machinery. As a fundamental component of the 3300 XL Proximity Transducer System, this probe provides precise, non-contact measurements of shaft vibration, axial position, and speed. Machinery protection systems rely heavily on this data to monitor fluid-film bearing performance, detect early mechanical anomalies, and prevent catastrophic equipment failures.

Application and Operation

This proximity probe operates primarily within Turbo-machinery Integration (TSI) and asset protection frameworks. Engineers frequently deploy this sensor on high-speed rotating equipment such as steam turbines, centrifugal compressors, heavy-duty pumps, and large electric motors. By establishing an electromagnetic field at the probe tip, the sensor accurately tracks the dynamic gap changes between the tip and the target shaft material, converting physical displacement into a reliable electrical signal for monitoring modules.

Technical Characteristics and Breakdown

The specific option code 330101-40-60-05-02-05 outlines a unique mechanical configuration engineered to fit distinct housing and mounting geometry requirements:

• Thread Profile: Features a standard 3/8-24 UNF English thread configuration for robust, direct-mount installation without an external armor sheath.
• Unthreaded Length: Utilizes a 4.0-inch unthreaded section, which facilitates deeper insertion into specific machine casings or brackets.
• Case Length: Measures 6.0 inches in total case length (correcting the typographical error in the source text regarding a 7.7-inch configuration), ensuring structural stability through the machine wall.
• Total Length: Configured with a 0.5-meter (approximately 1.6 feet) integrated cable length, which is designed to connect directly to an extension cable or nearby junction box.
• Connector Type: Features a miniature coaxial ClickLoc connector with gold-plated contacts, which minimizes signal loss and resists harsh environmental corrosion.
• Agency Approvals: Carries comprehensive international certifications, including ATEX, IECEx, and CSA, permitting safe deployment within explosive gas and hazardous industrial atmospheres.
