Description

Engineered for high-reliability vibration and position measurements in critical rotating machinery, the Bently Nevada 330102-00-20-05-02-00 is an industrial-grade 3300 XL 8 mm proximity probe configured with integrated protective armor. This non-contacting sensor measures static and dynamic distances between the probe tip and the observed target, typically a rotating shaft. It operates seamlessly as part of a complete 3300 XL transducer system, providing exceptionally stable voltage outputs proportional to the gap distance.

This specific configuration features a 3/8-24 UNF threaded case with a 2.0-inch overall length, fully threaded (0-inch unthreaded length). The probe body is coupled to a 0.5-meter (1.6 feet) armored coaxial cable terminated with a gold-plated, miniature coaxial ClickLoc connector. Designed for resilience in harsh environments, the probe structure provides robust resistance to oil, water, and chemical exposure commonly found in industrial turbomachinery environments.

Features

• Rugged Protective Armor: Features stainless steel flexible armor that protects the coaxial cable from physical damage, abrasion, and harsh operating conditions.
• ClickLoc Coaxial Connector: Equipped with a miniature coaxial ClickLoc connector providing a secure, vibration-resistant connection with low signal loss.
• High Thermal Stability: Engineered to maintain high measurement accuracy and linearity across a wide operating temperature range.
• Corrosion-Resistant Housing: Standard stainless steel case combined with a polyphenylene sulfide (PPS) probe tip ensures chemical and fluid compatibility.
• Direct Transducer Integration: Compatible with 3300 XL series Proximitor Sensors and extension cables for standard 5-meter or 9-meter system lengths.

Applications

• Steam and gas turbine shaft vibration and axial position monitoring.
• Centrifugal compressor radial dynamic motion tracking.
• High-speed gearbox shaft displacement and speed detection.
• Hydroelectric turbine guide bearing shaft orbit analysis.
• Industrial process pump and fan health monitoring.

Installation Guidelines

• Mechanical Clearance: Maintain a minimum radial clearance of 8.0 mm around the probe tip to prevent side-viewing interference from adjacent metal parts.
• Torque Limits: Tighten the probe body locknut within recommended limits for 3/8-24 threads (maximum 11 N-m or 100 in-lb) to avoid damage to the threaded case.
• Cable Routing: Ensure the armored cable is routed through protective conduit or trays away from high-voltage motor lines to mitigate electromagnetic noise.
• Connector Protection: Use silicone connector protectors or self-fusing tape to prevent fluid contamination at the ClickLoc junction.
