Quick Detail

Description

The 3300 NSv 8 mm Proximity Probe (Model 330901-00-70-10-02-05) is a high-precision eddy current sensor designed for industrial automation and critical rotating machinery monitoring. Engineered for centrifugal air compressors, refrigeration compressors, and process gas compressors, this probe is ideal for installations with restricted space or small target areas. Its 1/4-28 UNF threaded AISI 304 stainless steel case and Polyphenylene sulfide (PPS) probe tip provide excellent chemical resistance and mechanical robustness, ensuring reliable performance in harsh environments. Featuring a 1.0-meter miniature coaxial ClickLoc cable and multiple agency approvals, the 3300 NSv probe ensures secure connections and minimal signal loss, supporting linear ranges up to 1.5 mm (60 mils) with precise recommended gap settings of 1.0 mm (40 mils). With supply sensitivity under 2 mV/V and output resistance of 50 Ω, this probe delivers stable and accurate radial, axial, and tachometer measurements, making it ideal for applications where tight installation constraints and small shaft targets (<51 mm) are present. The 3300 NSv is backward compatible with 3300 RAM and 3000/7000-series systems, enabling seamless system upgrades while maintaining high reliability and precision in vibration monitoring, position sensing, and phase reference applications.

Applications

Radial Vibration Measurement
Used for monitoring radial vibration on shafts smaller than 51 mm. Provides high-resolution output with an average scale factor of 7.87 V/mm, enabling precise condition monitoring and early fault detection in compressors and turbines.

Axial (Thrust) Position Measurement
Ideal for axial position monitoring on flat targets smaller than 15 mm. Ensures accurate thrust measurements critical to fluid-filmed bearing machines and reduces the risk of mechanical failure.

Tachometer and Zero Speed Detection
Enables rotational speed monitoring and zero-speed detection with high repeatability, supporting automated shutdowns or speed-based control in process automation systems.

Phase Reference (Keyphasor Signal)
Generates Keyphasor signals for synchronization and phase monitoring of rotating machinery, enabling advanced predictive maintenance strategies and vibration analysis.

Small Target and Side-View Installations
Designed for applications with limited counterbore, side-view, or rear-view access. Provides reliable sensing in restricted spaces where conventional 3300 and 3300 XL probes cannot be used.

Specifications

Competitive Advantage

High Chemical and Temperature Resistance
Withstand temperatures from -52°C to +177°C and exposure to harsh process chemicals, offering superior reliability over standard 3300 RAM probes in challenging industrial environments.

Backward Compatibility
Mechanically and electrically compatible with 3300 RAM and 3000/7000-series transducer systems, facilitating cost-effective upgrades without replacing the entire monitoring system.

Robust Connection Design
Gold-plated ClickLoc connectors and CableLoc system provide secure electrical connections with pull strength up to 220 N, minimizing the risk of signal loss or connection failures.

Small Shaft and Target Precision
Optimized for small shafts and reduced side-view installations, delivering linear ranges of 1.5 mm (60 mils) with precise gap settings for accurate vibration and position measurements.

Proven Industrial Reliability
Constructed with AISI 304 stainless steel and PPS tip materials, the probe offers long-term durability, minimizing maintenance needs and ensuring consistent performance in critical process machinery.
