Bently Nevada 330171-05-63-05-02-05 3300 Series 5mm Proximity Probe

Description

Engineered for high-reliability vibration and position monitoring in critical industrial rotating machinery, the Bently Nevada 330171-05-63-05-02-05 is a premium proximity probe from the 3300 series. Featuring a 5mm tip diameter and standard 1/4-28 UNF threading, this probe is specifically designed to measure static and dynamic shaft displacement in fluid-film bearing machines.

This specific model configuration includes an unthreaded length of 0.5 inches combined with an overall case length of 6.3 inches. Equipped with a ClickLoc miniature coaxial connector, it ensures a secure, vibration-resistant connection to standard extension cables. It is built to withstand harsh operating conditions and carries multiple hazardous area agency approvals, making it highly suitable for power generation, petrochemical processing, and heavy mechanical industries.

Features

• Precise 5mm Tip: Optimized for small-clearance mounting environments requiring high-resolution displacement readings.
• ClickLoc Miniature Connector: Standard coaxial connector ensures secure connection and prevents accidental disconnections in high-vibration environments.
• Robust Threaded Case: 1/4-28 UNF threaded stainless steel housing provides mechanical durability and simplified installation.
• Hazardous Area Rating: Certified with multiple agency approvals for safe operation in explosive and classified industrial zones.

Applications

• Steam, gas, and hydro turbines
• Centrifugal, axial, and screw compressors
• High-speed industrial pumps and generators
• Gearbox shaft vibration and axial thrust position monitoring

Installation Guidelines

• Torque Limits: Do not exceed recommended mounting torque for 1/4-28 UNF threads to prevent deformation or damage to the probe case.
• Gap Calibration: Verify mechanical clearance and gap voltage using a physical feeler gauge or a calibrated voltmeter when connected to the Proximitor sensor before final tightening.
• Cable Routing: Ensure the coaxial cable is routed away from high-voltage lines and secured within protective conduit or tray systems to prevent physical damage and electrical noise interference.

Compliance and Certifications

• Multiple Approvals: Certified for hazardous environments (including ATEX, IECEx, and CSA standards).
