Quick Detail

Description

The 3300 NSv 1.5 mm Proximity Probe (model 330901-10-20-10-02-05) is a precision eddy current transducer designed for compact industrial applications, including centrifugal air compressors, refrigeration compressors, and process gas compressors. Engineered for tight spaces where side-view, rear-view, or counterbore limitations restrict standard Bently Nevada 3300 XL probes, this NSv probe provides high-resolution radial vibration and axial position measurements on shafts as small as 51 mm (2 in) or flat targets as small as 15 mm (0.6 in).

With a linear range of 1.5 mm (60 mils), output resistance of 50 Ω, and supply sensitivity under 2 mV per volt, the probe delivers precise readings for Keyphasor signals, tachometer speed measurements, and zero-speed detection. The probe body combines PPS tip material with AISI 304 stainless steel casing, providing superior chemical resistance for use in aggressive compressor environments. The 1/4-28 UNF threaded probe case supports maximum thread engagement of 0.375 in, while a miniature coaxial ClickLoc connector ensures secure and reliable electrical connections. The probe is compatible with existing 3300 RAM extension cables and monitoring systems, enabling straightforward system upgrades. Patented TipLoc and CableLoc designs provide robust tip bonding and 220 N pull strength, while connector protectors enhance protection against moisture ingress, ensuring stable operation in demanding industrial automation environments.

Applications

1. Radial Vibration Monitoring on Small Shafts
Monitors radial vibration on shafts smaller than 51 mm (2 in), enabling predictive maintenance for compact compressors and high-speed machinery, improving operational uptime by up to 30%.

2. Axial (Thrust) Position Measurement
Measures axial displacement on small flat surfaces (<15 mm), providing critical thrust monitoring for fluid-film bearings and automated machinery control.

3. Tachometer and Zero-Speed Measurement
Generates accurate rotational speed and zero-speed signals using the high-resolution 1.5 mm linear range, supporting rotational monitoring in refrigeration and process compressors.

4. Side-View or Rear-View Applications
Compact probe design allows installation in tight spaces with counterbore or obstructed views, where standard 3300 XL probes cannot be used, increasing system flexibility.

5. Chemical-Resistant Process Applications
Probe body materials (PPS tip and stainless steel case) provide enhanced chemical resistance, allowing operation in aggressive compressor and industrial environments without degradation of measurement accuracy.

Specifications

Competitive Advantage

1. Compact High-Precision Design
Provides 1.5 mm linear range for precise measurements in limited-space applications, outperforming 3000-series 190 transducers on small targets.

2. Superior Chemical and Mechanical Resistance
PPS probe tip and AISI 304 stainless steel case enhance durability and resistance to aggressive industrial environments, extending service life by 25%.

3. Patented TipLoc and CableLoc Technology
TipLoc bonding and CableLoc cable retention with 220 N pull strength ensure robust mechanical stability and minimize maintenance requirements.

4. Easy Integration and Upgrade Path
Mechanically and electrically compatible with 3300 RAM probes and extension cables, enabling simple retrofits without replacing the monitoring system.

5. Secure, Reliable Electrical Connection
Gold-plated ClickLoc connectors lock into place to prevent loosening; connector protectors reduce liquid ingress, ensuring consistent, high-fidelity signal output in harsh environments.
