Quick Detail

Description

The 330905-05-10-10-02-05 3300 NSv Proximity Probe is engineered for high-precision vibration and position monitoring in complex industrial automation systems. Designed for centrifugal air compressors, process gas compressors, refrigeration compressors, and other machinery with compact or constrained installation environments, this probe ensures accurate measurement in locations where standard Bently Nevada 3300 or 3300 XL 5 and 8 mm transducers are difficult to implement. Its specialized NSv design is particularly suited for applications with restricted counter bore, sideview, or rearview access.

Optimized for small target detection, the 3300 NSv Proximity Probe excels in measuring radial vibration on shafts smaller than 51 mm (2 in) or axial position on flat targets under 15 mm (0.6 in). Typical industrial automation applications include:

Radial vibration monitoring and radial shaft positioning

Axial (thrust) position detection

Tachometer and zero-speed sensing

Phase reference and Keyphasor signal acquisition

The 3300 NSv system can seamlessly replace older 3300 RAM Transducer Systems as well as 3000-series and 7000-series 190 transducers, providing an upgrade path without requiring major system modifications. When upgrading from a 3300 RAM setup, existing probes, extension cables, and monitoring hardware can remain in use with the new NSv Proximitor Sensor. Complete system upgrades from 3000-series or 7000-series transducers require replacement of the probe, cable, and Proximitor Sensor with NSv components.

With an average scale factor of 7.87 V/mm (200 mV/mil), the 3300 NSv Proximity Probe delivers the industry-standard output for eddy-current sensors, ensuring compatibility with existing automation monitoring systems. Its enhanced sideview capability and small-target design provide a linear range of 1.5 mm (60 mils), exceeding the linear performance of previous 3000-series 190 transducers.

Mechanically and electrically, the 3300 NSv probe is compatible with earlier 3300 RAM probes and extension cables. Its construction incorporates increased chemical resistance, enabling reliable operation in challenging process compressor environments. Multiple probe case configurations are available, including armored and unarmored threads in 1/4-28, 3/8-24, M8X1, and M10X1. The reverse-mount NSv probes support 3/8-24 or M10X1 threads.

Key automation-focused features include gold-plated ClickLoc connectors that ensure secure and reliable electrical connections, the patented TipLoc molding for robust probe-tip bonding, and CableLoc design providing 220 N (50 lb) pull strength to maintain secure cable attachment. Connector protectors are recommended to prevent liquid ingress, safeguarding signal integrity in demanding industrial conditions.

Overall, the 330905-05-10-10-02-05 3300 NSv Proximity Probe combines precise vibration and position sensing with rugged design and flexible installation, making it an essential component for industrial automation, predictive maintenance, and real-time machinery monitoring.

Applications

The 3300 NSv Proximity Probe (model 330905-05-10-10-02-05) is specifically engineered for high-precision vibration and position monitoring in critical rotating machinery with limited installation space. Its compact design and advanced side-view capabilities make it suitable for applications where standard Bently Nevada 3300 and 3300 XL probes cannot be accommodated.

Radial and Axial Measurement

This probe excels in measuring radial vibration on shafts smaller than 51 mm (2 in) and axial (thrust) position on flat targets under 15 mm (0.6 in). It provides reliable signals for tachometer, zero-speed detection, and phase reference (Keyphasor) applications, ensuring precise rotational speed and phase monitoring in centrifugal air compressors, refrigeration compressors, and process gas compressors.

Fluid-Filmed Bearing Applications

The probe is optimized for fluid-film bearing machinery, particularly in tight side-view or counter-bore restrictions. It supports radial vibration monitoring, axial position tracking, and phase reference measurements while withstanding harsh operational environments, including high temperatures from -52°C to +177°C (-62°F to +351°F).

Upgrade and Compatibility

The 3300 NSv Probe allows seamless upgrades from 3300 RAM and older 3000/7000-series 190 transducer systems, maintaining mechanical and electrical compatibility with existing extension cables and Proximitor Sensors. Its modular design simplifies installation and replacement in existing monitoring systems.

Harsh Environment and Chemical Resistance

Constructed with AISI 304 stainless steel and a polyphenylene sulfide (PPS) probe tip, the 3300 NSv Probe delivers exceptional durability and chemical resistance. The probe’s robust ClickLoc connectors and CableLoc design ensure secure connections with up to 220 N (50 lb) pull strength, making it ideal for industrial environments exposed to moisture or process fluids.

Small Target and Side-View Capability

The probe’s enhanced side-view design and 1.5 mm linear range provide superior performance in small-target scenarios compared to previous 3000-series 190 probes. This makes it highly suitable for compact machinery, reverse-mount installations, and areas with restricted access, without compromising signal accuracy or reliability.

In summary, the 3300 NSv Proximity Probe 330905-05-10-10-02-05 is a versatile, high-precision solution for vibration, axial position, tachometer, and phase reference monitoring in compact, high-performance industrial rotating equipment. Its combination of durability, chemical resistance, and compatibility with legacy systems ensures long-term operational reliability in demanding automation applications.
