Bently Nevada 330101-00-35-05-02-05 3300 XL Probe Proksimitinya 8 mm

Description

330101-00-35-05-02-05 is a 3300 XL 8 mm proximity probe configured with a fully threaded 3/8-24 UNF steel case (Option 00 unthreaded length), a 3.5 in overall case length (Option 35), and a 0.5-meter total cable length (Option 05). This non-contact eddy-current sensor is designed to provide highly accurate static position and dynamic vibration measurements for critical rotating machinery. Operating as part of a complete 3300 XL 8 mm monitoring chain, this probe delivers an output voltage directly proportional to the gap between the probe tip and the observed conductive target surface.

This specific variant features a standard, unarmored 75 Ohm triaxial cable terminated with a miniature coaxial ClickLoc connector (Option 02) and carries comprehensive hazardous area approvals (Option 05) including CSA, ATEX, and IECEx certifications. This configuration is widely deployed on fluid-film bearing machines, such as steam turbines, gas turbines, and compressors, where its 0.5-meter short probe lead length is optimal for coupling with a 4.5-meter extension cable to form a standard 5.0-meter transducer system. Unlike armored siblings, this non-armored design is lighter, more flexible, and ideal for installations utilizing dedicated protective conduit or internal routing paths.

Features

• Fully Threaded Body (Option 00): Features 0.0 inches of unthreaded length, enabling maximum threaded engagement and depth adjustability within standard 3/8-24 UNF machine ports.
• 3.5-Inch Case Length (Option 35): Provides a medium-reach 3.5-inch case depth, suitable for typical bearing housings and machine casings.
• 0.5-Meter Lead Length (Option 05): A short 0.5-meter (1.6 ft) total probe length designed to integrate into standard 5.0-meter monitoring chains when paired with a 4.5-meter extension cable.
• ClickLoc Coaxial Connection (Option 02): Outfitted with a miniature coaxial ClickLoc connector and standard unarmored triaxial FEP-insulated cable for a secure, finger-tight, low-loss physical interface.
• Hazardous Location Certification (Option 05): Approved by CSA, ATEX, and IECEx for installation in Class I Division 1/2 and Zone 0/2 environments.

Applications

• Radial vibration and shaft dynamic displacement monitoring on high-speed turbines and compressors.
• Thrust position and axial shaft thermal growth measurement in power generation machinery.
• Speed sensing and Keyphasor phase reference signal generation on critical machinery rotors.
• Confined-space installations where shorter probe leads are routed into a junction box before connecting to the main extension cable.

Installation Guidelines

• Mounting Torque: Recommended mounting torque is 11.2 N-m (100 in-lbf). Do not exceed the maximum rated torque of 33.9 N-m (300 in-lbf).
• Probe Gapping: Nominally gap the probe at 1.27 mm (50 mils), which corresponds to approximately -9 Vdc on the Proximitor Sensor output under radial vibration conditions.
• Cable Handling: Avoid sharp bends. Keep the cable routing curve above the minimum bend radius of 25.4 mm (1.0 in).
• Connection Integrity: Connect ClickLoc coaxial terminals finger-tight. Ensure connectors remain clean and dry; do not allow grease, oil, or industrial solvents to contaminate the gold-plated contact surfaces.
