Description

Engineered for deep-reach machinery monitoring, the Bently Nevada 330101-00-96-10-02-05 is a high-performance 8 mm Proximity Probe belonging to the industry-standard 3300 XL series. This unarmored probe utilizes the eddy-current measurement principle to provide non-contact, high-precision shaft vibration and position tracking on critical rotating machinery. By measuring the minute gap changes between the probe tip and target shaft (typically AISI 4140 steel), it provides critical diagnostic inputs to prevent catastrophic mechanical failure.

This specific configuration is highly tailored to solve access problems in tight or deep bearing assemblies. It features a fully threaded 3/8-24 UNF-2A stainless steel case with 0.0 inches of unthreaded length and an extensive 9.6-inch overall case length. It is equipped with a 1.0-meter (3.3 feet) standard coaxial cable terminating in a miniature male ClickLoc coaxial connector. Complete with Option 05 approvals, the probe is certified under ATEX, IECEx, and CSA standards for safe operation in explosive atmospheres, ensuring rugged performance in power generation, oil and gas, and petrochemical applications.

Features

• PPS Plastic Probe Tip: Highly ruggedized encapsulation protects the internal eddy-current coil against harsh industrial fluids and physical contact.
• Full-Length Threaded Body: Designed with 0.0 inches of unthreaded length and a 9.6-inch overall case length, enabling direct mechanical adjustment inside deep-reach bearing caps.
• Unarmored Coaxial Cable: Includes a highly flexible 1.0-meter standard coaxial cable suited for routing through protective field conduits.
• Miniature ClickLoc Connector: Gold-plated brass connector ensures robust electrical connectivity and reliable vibration signal transmission to the extension cable.
• Hazardous Area Certified: Pre-approved with CSA, ATEX, and IECEx certifications (Option 05) for reliable installation in hazardous plant zones.

Applications

This proximity probe is optimized for non-contact displacement monitoring inside demanding rotating machinery assemblies, including:

• Radial vibration and shaft centerline tracking in steam and gas turbines.
• Axial thrust position displacement measurements on high-speed compressors.
• Rotor movement and thermal expansion monitoring in industrial pumps and gearboxes.
• Permanent machine casing installations requiring deep physical probe insertion.

Installation Guidelines

To secure reliable signal performance and preserve warranty coverage, adhere to these technical installation practices:

• Adjust the probe gap mechanically during installation to match the calibrated center point of the linear range (nominally 1.27 mm or 50 mils corresponding to -10 Vdc bias output).
• Verify that the maximum thread engagement does not exceed the mechanical limits to prevent thread damage or binding within the bracket.
• Route the unarmored coaxial cable through dedicated metal conduit or cable trays to prevent electrical noise interference from nearby machinery power cables.
• Connect only to fully compatible 3300 XL 8 mm system components, including 330180 series Proximitor sensors and 330130 standard extension cables.

Compliance and Certifications

Equipped with Agency Approval Option 05, this device satisfies standard international safety regulations for deployment in explosive environments:

• CSA: Intrinsic Safety and Non-Incendive certifications for hazardous locations.
• ATEX: Compliant with standard European Union explosive atmosphere guidelines.
• IECEx: Globally recognized intrinsic safety standards for zone-classified environments.
