Description
The 330908-00-20-70-02-05 3300 NSv Proximity Probe is a precision eddy-current sensor designed for advanced industrial automation and condition monitoring applications where space is limited. Engineered for use with the 3300 XL NSv Transducer System, this probe provides highly accurate radial vibration, axial thrust, and Keyphasor phase reference signals on high-speed compressors, process gas machinery, and fluid-film bearing equipment. Its 3/8-24 UNF threaded stainless steel housing and chemically resistant PPS probe tip allow reliable operation across a wide temperature range from -52°C to +177°C (-62°F to +351°F). With a 1.5 mm linear range and a recommended 1.0 mm gap, the probe is suitable for tight installations. The included 7-meter (23-foot) standard cable with miniature ClickLoc connector ensures secure connection and integration with automated monitoring systems in predictive maintenance and vibration control.
Applications
Centrifugal Compressor Vibration Monitoring
Measures radial vibration on shafts smaller than 51 mm, providing precise feedback for predictive maintenance and real-time condition monitoring.
Axial Thrust and Position Feedback
Delivers accurate axial (thrust) position measurement on flat targets under 15 mm, optimizing fluid-film bearing performance in refrigeration and process compressors.
Keyphasor and Phase Reference Applications
Supports high-precision phase reference signals for tachometer functions and rotor synchronization in automated industrial control systems.
Fluid-Film Bearing Zero-Speed Monitoring
Enables detection of zero speed and start-up ramp analysis, safeguarding rotating machinery and reducing unplanned downtime in industrial automation.
Space-Constrained Automation Installations
Compact design allows installation in tight spaces with side-view, rear-view, or counterbore restrictions while maintaining accurate measurement and process control.
