Quick Detail

Description

The 330904-00-25-05-02-CN 3300 NSv Proximity Probe is a compact eddy-current sensing device designed for industrial automation systems requiring reliable non-contact vibration and position measurement in confined environments. Compatible with the 3300 NSv Transducer System, the probe delivers accurate radial vibration, axial thrust, and phase reference signals for high-speed compressors, fluid-film bearing machines, and rotating equipment with limited counterbore or side-view clearance. Featuring a linear range of 1.5 mm and a recommended gap setting of 1.0 mm, the stainless-steel M8X1 threaded housing and PPS tip ensure durable performance across extreme temperatures from -52°C to +177°C. With a 250 mm overall case length and ClickLoc miniature coaxial connector, the 330904-00-25-05-02-CN probe integrates seamlessly into condition monitoring and predictive maintenance architectures used in petrochemical, refrigeration, and process automation industries, supporting long-term machine protection and operational efficiency.

Applications

Centrifugal Compressor Radial Vibration Sensing
Ideal for radial vibration diagnostics on compressors with shaft diameters under 51 mm, enabling stable monitoring for predictive maintenance routines.

Axial (Thrust) Position Measurement in Refrigeration Compressors
Supports thrust position detection on refrigeration equipment using a recommended 1.0 mm gap for accurate displacement and load feedback.

Phase Reference for High-Speed Rotating Machinery
Provides Keyphasor outputs for synchronization and phase analysis in high-speed turbomachinery within industrial automation systems.

Small Target Feedback in Process Automation
Handles flat targets smaller than 15 mm, improving sensing precision in tight mechanical layouts and dynamic control loops.

Zero-Speed and Tachometric Measurement for Fluid-Film Bearings
Enables zero-speed and startup ramp monitoring for fluid-film bearing machines, optimizing asset performance during transient operations.

Specifications

Competitive Advantage

Extended Case Length for Complex Installations
The 250 mm case length simplifies installation in deep bore or restricted-access compressor housings compared to standard probe geometries.

Wide Temperature Range and Material Durability
Operational temperatures from -52°C to +177°C with AISI 304 stainless steel housing and PPS tip provide superior environmental resilience.

High Signal Fidelity and Scale Factor Performance
Designed for the NSv system with a 7.87 V/mm scale factor, ensuring linear vibration and displacement outputs for advanced diagnostics.

Chemical-Resistant Design for Process Gas Applications
Chemical resistance improves longevity in petrochemical and gas processing environments vs. legacy RAM series probes.

ClickLoc Connector Reliability and System Compatibility
Gold-plated ClickLoc connectors ensure secure mechanical coupling and backward compatibility with 3300 RAM cable assemblies for reduced upgrade cost.
