Bently Nevada 330101-00-26-10-02-05 3300 XL 8 mm Proximity Probe

Description

The Bently Nevada 330101-00-26-10-02-05 is a high-performance, non-contacting 8 mm proximity probe engineered for critical machinery protection and condition monitoring chains. This specific configuration is defined by a completely threaded 2.6-inch stainless steel case (0.0-inch unthreaded length) and an integrated 1.0-meter (3.3 feet) non-armored standard cable. Terminated with a miniature coaxial ClickLoc connector, it is optimized for direct installation in bearing housings, machine casings, or close-coupled wells where mechanical abrasion shielding is not required. By pairing with a compatible 3300 XL Proximitor sensor and extension cable, this eddy-current transducer delivers highly accurate, repeatable displacement measurements for steam and gas turbine shafts, compressor rotors, and generator vibration monitors. This configuration includes the -05 agency option, making it certified under ATEX, IECEx, and CSA standards for safe deployment in hazardous locations.

Features

• Fully Threaded Case: A 0.0-inch unthreaded length paired with a 2.6-inch overall case length provides maximum mounting depth versatility in shallow or threaded machine wells.
• 1.0-Meter Integrated Cable: Standard non-armored triaxial cable offers optimal flexibility for clean routing within protective conduit or machine enclosures.
• ClickLoc Coaxial Connection: Equipped with a miniature male ClickLoc coaxial connector (option 02) designed for robust, tool-free connection to 3300 XL extension cables.
• Hazardous Location Certification: Fully certified under CSA, ATEX, and IECEx approvals (-05 option) for intrinsically safe operation in industrial environments.
• PPS Molded Tip: Rugged 8 mm probe tip constructed from Polyphenylene sulfide (PPS) for superior resistance to high temperatures, chemical erosion, and physical impact.
• TipLoc & CableLoc Security: Built using Bently Nevada patented molding techniques to ensure an incredibly strong mechanical bond between the probe tip, case, and FEP cable jacket.

Applications

• Turbine & Compressor Vibration: Radial vibration and axial shaft position measurements on critical steam/gas turbines, turbo-compressors, and high-speed gearboxes.
• Thrust Position Monitoring: Direct measurement of rotor axial displacement to prevent catastrophic bearing failure.
• Conduit-Protected Runs: Highly suitable for installations where cables are run through dedicated rigid or flexible conduit, rendering heavy metal armor unnecessary.
• Explosive Gas Environments: Safe installation in petrochemical refineries, natural gas processing facilities, and power generation plants.

Installation Guidelines

• Gap Adjustment: Calibrate and physically gap the probe using a micrometer or voltmeter to read -9 Vdc at the center of the linear monitoring range.
• Torque Limits: Do not exceed the maximum rated installation torque of 11.2 Nm (100 in-lbf) for standard forward-mounted probes to prevent casing deformation.
• Thread Engagement Limits: Keep maximum thread engagement under 0.563 inches (14.3 mm) to avoid potential thread binding in blind tapped holes.
• Cable Bend Management: Never route the FEP triaxial cable with a bend radius tighter than 25.4 mm (1.0 in) to protect the internal coaxial shield.
• Pressure Seal Integrity: Protect the probe from operating temperatures below -34 degC (-30 degF) to preserve the Viton O-ring pressure seal integrity.

Compliance and Certifications

• Hazardous Area Classifications: Approved under ATEX, IECEx, and CSA standards for intrinsically safe and non-incendive environments.
• Intrinsic Safety Entity Parameters: Ui = -28V, Ii = 140 mA, Pi = 0.91W, Ci = 1.5 nF, Li = 610 uH when connected per installation drawing 141092.
