Quick Detail

Description

The 330903-00-06-05-02-CN 3300 NSv Proximity Probe is engineered for high-precision vibration and shaft position measurement in industrial automation and rotating machinery monitoring systems. Designed for Bently Nevada NSv proximity transducer architectures, this probe provides accurate radial vibration, axial position, and phase reference measurements on machinery with restricted installation geometries, such as centrifugal compressors, refrigeration compressors, and process gas compressors. Featuring a compact 60 mm case length, M8×1 threaded mounting, 0.5-meter cable, and PPS probe tip, the 330903-00-06-05-02-CN offers enhanced performance for small target applications and reduced side-view configurations. Its −52°C to +177°C temperature capability, 1.5 mm linear range, and consistent 50-ohm output resistance ensure stable operation under harsh industrial thermal and chemical environments. Within automated condition monitoring frameworks, this NSv Proximity Probe enables reliable data acquisition for predictive maintenance, reduced downtime, and advanced diagnostics across petrochemical, refining, and energy-intensive sectors.

Applications

Small Shaft Vibration Monitoring
Applied to compressors with shaft diameters below 51 mm where conventional 5 mm and 8 mm probes cannot be installed. The 1.5 mm linear range facilitates precise radial vibration measurement for imbalance and misalignment diagnosis.

Axial (Thrust) Position Measurement
Used for thrust position detection in fluid-film bearing machines. The −52°C to +177°C operating range supports thermally dynamic environments in petrochemical and refrigeration units.

Keyphasor Phase Reference Signal Acquisition
Provides accurate phase reference signals for vibration signature analysis and rotor dynamic studies, ensuring synchronized diagnostics in digital condition monitoring systems.

Tachometer and Zero-Speed Measurement
Supports accurate speed measurement and startup sequencing in compressor control loops, maintaining signal integrity through a 0.5-meter miniature coaxial ClickLoc cable.

Specifications

Competitive Advantage

Enhanced Space-Restricted Installation Capability
M8×1 threading and compact 60 mm case design enable probe installation where counter-bore or rear-view limitations make standard probes unusable.

High Temperature and Chemical Resistance
PPS tip and stainless steel case provide durability from −52°C to +177°C, with improved chemical resistance over legacy 3300 RAM probes for process compressor environments.

Stable Electrical Output for Accurate Diagnostics
50-ohm output resistance and reduced supply sensitivity (<2 mV/V) ensure consistent voltage-to-gap scaling for vibration and displacement measurements.

Backward Compatibility for Cost-Effective Upgrades
Mechanical and electrical compatibility with earlier 3300 RAM systems allows incremental upgrades and reduced transition costs within existing monitoring networks.

Robust Connector and Cable Reliability
Miniature ClickLoc connectors prevent loosening and signal degradation during operation, supporting long-term performance in harsh industrial vibration environments.
