Description

The Bently Nevada 330101-00-12-05-02-CN is an eddy current non-contacting sensor designed for high-precision static and dynamic distance measurements in industrial machinery protection and asset condition monitoring applications. This high-performance 3300 XL 8 mm proximity probe utilizes a 3/8-24 UNF threaded standard mount configuration without armor, enabling precise tracking of radial vibration, shaft axial position, overspeed status, and Keyphasor timing references on fluid-film bearing machinery. Built with a robust polyphenylene sulfide (PPS) molded plastic tip and a premium AISI 303 or 304 stainless steel case, the sensor ensures ultimate mechanical longevity and reliable chemical resistance in severe operating environments. This specific model features a 0.5-metre total length combined with a gold-plated miniature coaxial ClickLoc connector for secure, finger-tight field connection to a 3300 XL extension cable and Proximitor sensor. The 330101-00-12-05-02-CN probe is fully backward-compatible with legacy non-XL 3300 series proximity monitoring platforms and features the dedicated -CN suffix representing regional compliance certification for specialized industrial deployments.

Features

• Patented Mechanical Bonding: Employs an advanced TipLoc molding process to forge an exceptionally secure structural bond between the probe tip and the stainless steel body.
• Enhanced Cable Strain Relief: Features a patented CableLoc internal clamp design providing up to 330 N (75 lbf) of pull strength to prevent separation of the lead from the probe body.
• ClickLoc Interconnect Technology: Equipped with a gold-plated, corrosion-resistant coaxial connector that provides a positive tactile "click" lock mechanism to eliminate accidental loosening without special tools.
• Exceptional Environmental Tolerance: Formulated to withstand rigorous machine ambient conditions with structural sealing designed to tolerate high humidity, temperature swings, and chemical exposure.
• Interchangeable Calibration: Fully supports structural interchangeability across standard 3300 XL elements without requiring time-consuming manual bench calibration or component matching.

Installation Guidelines

• Mechanical Installation Torque: When mounting the forward-threaded probe case into the machine bracket or housing, tighten up to a maximum recommended torque of 11.2 N-m (100 in-lbf) to prevent structural damage to the threads or internal core.
• Cross-Talk Minimization: Maintain a clear distance separating neighboring sensor tips of at least 40 mm (1.6 in) for parallel axial position loops, and 38 mm (1.5 in) for adjacent radial vibration arrangements to ensure unintended system cross-talk remains under 50 mV.
• Minimum Target Footprint: Ensure the observed rotating target shaft area provides a minimum surface diameter of at least 15.2 mm (0.6 in) for a flat target, and a minimum structural shaft diameter of 50.8 mm (2.0 in) for optimal tracking precision.
• Connector Environmental Sealing: Always install specialized connector protectors or use dedicated environmental protection kits over the probe lead connection point to secure the triaxial junction against oil ingestion or humidity degradation.
