Quick Detail

Description

The 3300 NSv 330903-05-19-05-02-00 Proximity Probe is a high-performance industrial automation sensor engineered for compact and constrained machinery environments. Designed for centrifugal air compressors, refrigeration compressors, and process gas compressors, this probe excels where tight installation clearances or small shaft diameters prevent the use of standard 3300 or 3300 XL probes. With an unthreaded length of 50 mm, overall case length of 190 mm, and 0.5-meter miniature coaxial ClickLoc connector cable, it delivers precise radial and axial position measurements even in side-view or counterbore restricted areas.

Constructed with a polyphenylene sulfide (PPS) probe tip and AISI 304 stainless steel case, the 3300 NSv probe resists chemical and thermal stress, operating in temperatures from -52°C to +177°C (-62°F to +351°F). Its 1.5 mm linear range and recommended 1.0 mm gap enable high-accuracy eddy current measurements on shafts as small as 50.8 mm (2 in) and flat targets smaller than 15 mm (0.6 in). The TipLoc and CableLoc designs ensure robust mechanical attachment with up to 220 N (50 lb) pull strength, while gold-plated ClickLoc connectors maintain electrical integrity in harsh industrial conditions.

Mechanically and electrically compatible with previous 3300 RAM, 3000-series, and 7000-series 190 transducer systems, the 3300 NSv probe provides seamless upgrades for existing monitoring systems. Its compact design, combined with enhanced side-view and small-target characteristics, makes it ideal for automation systems where precise position and vibration measurements are critical. Optional connector protectors enhance protection against fluid ingress, ensuring reliable operation in high-humidity or process environments.

Applications

1. Radial Vibration and Position Measurement
Accurately measures radial shaft vibration for compressors and turbines with small shafts (<51 mm), preventing mechanical failures and maintaining optimal automation control.

2. Axial (Thrust) Position Monitoring
Monitors axial movement on compact machinery with limited access, enabling preventive maintenance and machine longevity.

3. Tachometer and Zero-Speed Detection
Provides reliable speed signals for rotational machinery control, ensuring synchronized operation and precise automation timing.

4. Phase Reference (Keyphasor) Signals
Generates accurate phase reference signals for vibration monitoring systems, supporting real-time diagnostics and condition-based monitoring.

5. Small Target Measurement in Constrained Spaces
Ideal for side-view or rear-view restricted environments, measuring targets as small as 15 mm, maintaining automation performance where standard probes cannot be installed.

Specifications

Competitive Advantage

1. Compact and Flexible Design
The NSv probe’s reduced unthreaded length (50 mm) and 190 mm case allows installation in restricted spaces, outperforming standard 3300 XL probes.

2. Extended Environmental Resistance
PPS probe tip and stainless steel case allow operation from -52°C to +177°C, making it suitable for chemical and high-temperature process environments.

3. High-Strength Mechanical Connection
TipLoc and CableLoc designs provide up to 220 N pull strength, preventing cable detachment under vibration or mechanical stress.

4. Electrical Integrity in Harsh Conditions
Gold-plated ClickLoc connectors with optional connector protectors ensure signal reliability in oil, moisture, or high-humidity industrial environments.

5. Seamless System Upgrade
Compatible with 3300 RAM, 3000-series, and 7000-series 190 probes, enabling cost-effective upgrades without redesigning the monitoring system.
