Quick Detail

Description

The 330904-00-25-05-02-05 3300 NSv Proximity Probe is a precision eddy current sensor designed for automated machinery monitoring in industrial environments. Built for use with centrifugal air compressors, refrigeration compressors, process gas compressors, and other compact machinery, the 3300 NSv enables accurate measurement of radial vibration, axial position, and shaft speed in tight installation areas. Its M8X1 threaded stainless-steel probe case ensures durability, while the polyphenylene sulfide (PPS) probe tip offers enhanced chemical resistance, making it ideal for harsh process conditions. With a linear range of 1.5 mm (60 mils) and recommended gap of 1.0 mm (40 mils), this sensor provides high-precision displacement data, compatible with 24 VDC supply and 4–20 mA monitoring systems. The miniature coaxial ClickLoc connector, combined with the patented TipLoc and CableLoc designs, ensures secure connections and robust signal integrity under continuous industrial operation. Operating reliably in temperatures from -52°C to +177°C (-62°F to +351°F), the 3300 NSv Proximity Probe offers superior small-target sensing capabilities, outperforming older 3300 RAM and 3000-series transducers, while maintaining compatibility with existing 3300 extension cables and monitoring hardware.

Applications

1. Radial Vibration Measurement on Small Shafts
Designed for shafts smaller than 51 mm (2 in), the 3300 NSv accurately monitors radial vibration, enabling predictive maintenance and early detection of imbalance or misalignment in centrifugal compressors.

2. Axial (Thrust) Position Measurement
Measures axial shaft displacement on flat targets as small as 15 mm (0.6 in), allowing precise control in compressors and pumps with fluid-film bearings.

3. Tachometer and Zero-Speed Detection
Provides accurate shaft speed and zero-speed feedback using 4–20 mA output, facilitating automated shutdowns and control system integration.

4. Phase Reference (Keyphasor) Signal Generation
Generates reliable Keyphasor signals for vibration phase analysis and rotor dynamics monitoring, critical in automated process control systems.

5. Retrofit and Upgrade of Legacy Systems
Compatible with 3300 RAM and 3000/7000-series systems, enabling seamless upgrades without replacing the entire monitoring infrastructure, saving costs and minimizing downtime.

Specifications

Competitive Advantage

1. Enhanced Side-View Capability
The 3300 NSv supports side-view or rear-view installations where standard transducers cannot fit, allowing flexible placement in space-constrained machinery.

2. Superior Chemical Resistance
The PPS probe tip and AISI 304 stainless steel case resist harsh chemicals, enabling reliable operation in challenging compressor and process environments.

3. Robust Electrical and Mechanical Connection
ClickLoc connectors with TipLoc and CableLoc designs ensure high signal integrity and up to 220 N pull strength, preventing accidental disconnections.

4. High-Precision Measurement
1.5 mm linear range with 7.87 V/mm scale factor provides accurate displacement readings, exceeding older 3000-series transducers for small-target applications.

5. Broad Temperature Range
Operating from -52°C to +177°C (-62°F to +351°F) and storage at the same range ensures dependable performance in extreme industrial conditions.
