Bently Nevada 330101-00-60-10-02-05 3300 XL 8 mm Proximity Probe

Description

The Bently Nevada 330101-00-60-10-02-05 is a high-performance 8 mm proximity probe engineered for the industry-proven 3300 XL 8 mm Proximity Transducer System. This specific variant is defined by a 3/8-24 UNF-2A thread configuration without protective armor, a 0.0-inch unthreaded length (meaning it features a fully threaded body), a 6.0-inch overall case length, a 1.0-meter total cable length, and standard ClickLoc connectors. It is complete with the -05 agency approval option, certifying it for installation in hazardous areas with CSA, ATEX, and IECEx approvals. Unlike armored or fluid-blocked configurations, this unarmored, fully threaded 6.0-inch probe is optimized for standard bearing housing and dry-well installations where routing is sheltered inside existing protective conduit, providing precise, non-contact shaft position and vibration data.

Operating on the eddy current principle, the probe measures the non-contact static and dynamic displacement of a rotating shaft relative to a stationary reference. It interfaces directly with a 330180 series 3300 XL Proximitor sensor and a 330130 series extension cable to form a complete 5-meter or 9-meter transducer chain, delivering accurate diagnostic signals directly to machinery protection systems such as the Bently Nevada 3500 series rack.

Features

• Unarmored Design (330101): Engineered for simplified routing within existing protective conduits or machine casings without the extra bulk of integrated armor.
• Fully Threaded Body: Zero unthreaded length (0.0 in) ensures full thread engagement along the entire 6.0-inch casing, allowing versatile depth adjustments inside threaded ports.
• Extensive 6.0-Inch Case: Extended reach enables deep penetration through thick machine casings, housings, or bearing caps directly to the shaft surface.
• Standard 1.0-Meter Cable: Standard coaxial cable with a 1.0-meter length, optimized for termination at external terminal boxes or junction housings.
• ClickLoc Coaxial Connector: Features a gold-plated brass miniature connector with a positive locking click mechanism that resists mechanical vibration and accidental disconnection.
• Hazardous Area Approval (-05): Complete with CSA, ATEX, and IECEx approvals for safe installation in Zone 0, Zone 1, and Zone 2 environments.
• Robust Construction: Built with a high-durability polyphenylene sulfide (PPS) molded tip and a stainless steel case for continuous operation in wet, oily, and corrosive environments.

Applications

This proximity probe is a key component in machinery protection and condition monitoring programs across heavy industrial environments, including:

• Radial vibration monitoring of steam turbines, gas turbines, and generators.
• Axial thrust position and rotor displacement measurement in high-speed compressors, pumps, and gearboxes.
• Shaft eccentricity and dynamic motion tracking in critical rotating machinery.
• Continuous monitoring in hazardous process areas such as oil and gas, petrochemical, and power generation facilities.

Installation Guidelines

To ensure optimal accuracy and longevity of your 3300 XL proximity probe, adhere to the following standard engineering installation practices:

• Probe Gap Calibration: Adjust the mechanical gap between the probe tip and the target material (typically AISI 4140 steel) using a micrometer or voltmeter to match your system's calibrated dynamic range (typically gapped at 1.27 mm or 50 mils).
• Thread Engagement: Do not exceed thread engagement limits during mounting to prevent mechanical binding. The maximum recommended thread engagement for 3/8-24 threads is 0.563 inches.
• Torque Limits: Hand-tighten the probe case and use a torque wrench to apply the recommended installation torque of 7.5 N-m (66 in-lbf). Do not exceed the maximum rated torque of 22.6 N-m (200 in-lbf) to prevent case deformation.
• Cable Protection: Route the coaxial cable inside standard protective conduit or secure it away from sharp edges. Ensure the minimum bend radius of 25.4 mm (1.0 inch) is maintained at all times.
• Grounding and Shielding: Connect the probe coaxial connector firmly to the extension cable. Ensure proper shielding is maintained through to the Proximitor sensor and that the transducer system is grounded per Bently Nevada drawing 141092 (intrinsically safe) or 140979 (non-incendive).
