The Bently Nevada 330101-00-11-20-02-CN is a 3300 XL 8 mm proximity probe designed for use within eddy current proximity transducer systems. This probe provides precise measurement of shaft vibration and position in rotating machinery, ensuring compatibility with the 3300 XL series monitoring systems.

Features

• 8 mm probe diameter with 3/8-24 UNF thread
• Miniature coaxial ClickLoc connector for secure, reliable signal transmission
• Standard cable configuration with 2.0 meter total length
• Designed for complete interchangeability with 3300 XL series probes, extension cables, and Proximitor sensors
• Complies with API 670 standards for mechanical configuration, linear range, and accuracy
• Hazardous area approvals including CSA, ATEX, and IECEx

Applications

• Turbines: Monitoring shaft vibration and axial thrust in gas and steam turbines
• Compressors: Centrifugal, axial, and reciprocating compressor monitoring
• Motors and Generators: Assessing stability and bearing health
• Pumps: Dynamic vibration and shaft position monitoring for high-energy pumps
• Gearboxes: Tracking internal shaft movement and speed for wear detection

Technical Specifications

Installation Guidelines

• Ensure the probe is mounted in a rigid, vibration-free bracket to prevent false readings.
• The probe is factory-calibrated for AISI 4140 steel; using different target materials will require recalibration of the scale factor.
• For radial vibration applications, the recommended gap setting is 1.27 mm (50 mils), corresponding to approximately -9 Vdc.
• ClickLoc connectors should be tightened until they audibly "click" to ensure a secure lock.
• Handle with care to avoid damage to the probe tip or cable insulation.
• Always power down the monitoring system before connecting or disconnecting transducer components.
