Quick Detail

Description

The 330903-00-05-50-02-05 3300 NSv Proximity Probe is a compact, high-performance eddy-current transducer designed for industrial automation and tight installation environments. With an overall case length of 50 mm and M8X1 threaded 12 mm probe case, the NSv probe accommodates sideview, rearview, and counterbore restrictions commonly encountered in centrifugal air compressors, refrigeration compressors, and process gas compressors. Equipped with a 5.0-meter (16.4 feet) miniature coaxial ClickLoc cable, it ensures secure electrical connectivity, while the patented TipLoc molding and CableLoc design provide 220 N (50 lb) pull strength, protecting the probe tip and cable from mechanical stress. Constructed from AISI 304 stainless steel with a polyphenylene sulfide (PPS) probe tip, it delivers robust chemical and temperature resistance, operating across -52°C to +177°C (-62°F to +351°F). The probe maintains a linear range of 1.5 mm (60 mils) and a recommended gap of 1.0 mm (40 mils), with output resistance of 50 Ω and supply sensitivity under 2 mV per volt, ensuring precise radial and axial vibration, position, and speed measurements. Fully compatible with 3300 XL NSv Proximitor sensors, this probe supports system upgrades from 3300 RAM and 3000/7000 series systems, offering reliable interchangeability and enhanced performance in small-shaft or restricted-space applications.

Applications

1. Centrifugal Compressor Radial Vibration Monitoring
The NSv probe measures radial vibration on shafts as small as 51 mm (2 in), providing critical feedback for vibration monitoring systems and preventing bearing damage in process compressors.

2. Axial (Thrust) Position Measurement
The probe accurately tracks axial position on flat targets under 15 mm (0.6 in), enabling precise thrust monitoring and automated shaft alignment in limited space applications.

3. Process Gas and Refrigeration Compressor Monitoring
With its chemical-resistant PPS tip and stainless steel case, the NSv probe operates reliably in harsh process gas environments while maintaining high-precision signal output.

4. Keyphasor and Tachometer Signal Generation
The NSv probe delivers accurate phase reference (Keyphasor) and zero-speed signals for speed and phase monitoring, supporting predictive maintenance and control in industrial automation.

5. Small Target or Sideview Restricted Applications
Designed for tight spaces with sideview or counterbore limitations, the NSv probe ensures continuous position and vibration monitoring where standard 3300 XL probes cannot be installed.

Specifications

Competitive Advantage

1. Compact Design for Restricted Installations
With an overall length of 50 mm and small probe tip, the NSv probe fits into constrained areas, enabling installation in machines with counterbore or sideview restrictions.

2. Superior Mechanical Strength
Patented CableLoc design provides 220 N (50 lb) pull strength, while TipLoc molding ensures the probe tip remains firmly bonded to the probe body, minimizing maintenance interruptions.

3. Broad Temperature and Chemical Resistance
Operating across -52°C to +177°C (-62°F to +351°F) and made with PPS and stainless steel, the NSv probe withstands harsh chemical and thermal environments typical in industrial compressors.

4. Full System Interchangeability
Compatible with 3300 XL NSv Proximitor Sensors and prior 3300 RAM systems, the probe allows system upgrades without extensive recalibration or component replacement.

5. Precision Signal Stability
With a linear range of 1.5 mm, output resistance of 50 Ω, and supply sensitivity below 2 mV per volt, the NSv probe delivers stable, accurate radial, axial, and speed measurements for automated monitoring systems.
