Quick Detail

Description

The 3300 NSv Proximity Probe is a precision eddy current transducer system engineered for use in highly constrained industrial environments, including centrifugal air compressors, refrigeration compressors, and process gas compressors. Its design is specifically tailored for applications where installation space is limited, making it ideal for machinery with tight clearances or compact shaft arrangements. The 3300 NSv Probes excel in scenarios where standard Bently Nevada 3300 and 3300 XL transducers cannot be accommodated due to counter bore, side-view, or rear-view restrictions.

These probes are particularly suited for small target measurement applications, including radial vibration on shafts under 51 mm (2 in) diameter and axial position on flat targets smaller than 15 mm (0.6 in). Core measurement capabilities include:

Radial vibration and shaft position detection

Axial (thrust) position measurement

Tachometer and zero-speed monitoring

Phase reference signal acquisition (Keyphasor outputs)

The 3300 NSv system provides an average scale factor of 7.87 V/mm (200 mV/mil), a standard output for eddy current transducers, ensuring reliable and consistent signal performance. Its compact design enables shorter linear ranges while maintaining precise measurement over 1.5 mm (60 mils), exceeding the performance of legacy 3000-series 190 transducers.

Mechanically and electrically, the NSv probe is fully compatible with prior 3300 RAM probes and extension cables, facilitating smooth system upgrades without replacing existing monitoring hardware. The probes offer superior chemical resistance, making them suitable for a wide variety of process compressor applications. Additionally, the side-view capability ensures optimal gapping and measurement accuracy even in challenging installation geometries.

The 3300 NSv Probes are available in multiple case and thread configurations, including armored and unarmored 1/4-28, 3/8-24, M8x1, and M10x1 options. Reverse-mount configurations are offered with standard 3/8-24 or M10x1 threads. All probes feature gold-plated ClickLoc connectors, which lock securely and prevent loosening, while Bently Nevada’s patented TipLoc molding and CableLoc designs provide exceptional mechanical integrity and up to 220 N (50 lb) pull strength. Connector protectors are recommended to safeguard the electrical interface from moisture and contamination.

In summary, the 3300 NSv Proximity Probe is a compact, highly versatile solution for precision vibration and position monitoring in confined spaces, combining robust mechanical design, superior chemical resistance, and compatibility with existing Bently Nevada monitoring systems. Its unique configuration options and small-target capabilities make it a preferred choice for modern automated machinery where space and performance are critical.

Applications

The 3300 NSv Proximity Probe is specifically designed for high-precision vibration and position monitoring in industrial machinery where installation space is limited. Its compact design and specialized features make it ideal for use in centrifugal air compressors, refrigeration compressors, process gas compressors, and other fluid-filmed bearing machines with tight installation requirements.

Radial and Axial Measurements

This probe excels at measuring radial vibration and radial position on shafts smaller than 51 mm (2 in), as well as axial (thrust) position on flat targets smaller than 15 mm (0.6 in). Its small tip and advanced side-view capabilities allow accurate monitoring even in areas where traditional probes cannot be installed due to space or alignment restrictions.

Tachometer and Speed Detection

The 3300 NSv probe is suitable for tachometer and zero-speed measurements, providing reliable phase reference (Keyphasor) signals. This makes it an excellent choice for applications requiring precise shaft speed monitoring and synchronization in complex machinery systems.

Retrofit and Upgrade Applications

The probe can replace older 3300 RAM and 3000-/7000-series 190 transducer systems, allowing existing systems to be upgraded without a full overhaul. When upgrading from 3300 RAM systems, the existing probe, extension cable, and monitoring system can remain, minimizing downtime and cost. For 3000- or 7000-series systems, the probe, cable, and Proximitor sensor are replaced with NSv components for full system compatibility.

Process Compatibility

Constructed with AISI 304 stainless steel cases and polyphenylene sulfide (PPS) probe tips, the NSv probe offers excellent chemical and temperature resistance, capable of operating from -52°C to +177°C (-62°F to +351°F). This makes it suitable for demanding process compressor environments where chemical exposure or temperature extremes are common.

Installation Flexibility

The probe supports multiple thread sizes, including M10X1, and comes with Miniature coaxial ClickLoc connectors, ensuring secure, vibration-resistant connections. Features such as the TipLoc molding and CableLoc design enhance mechanical robustness and prevent signal degradation from cable stress or liquid ingress.

Specifications

Competitive Advantage

The 3300 NSv Proximity Probe combines compact design, high precision, and robust construction, making it ideal for tight installation spaces and small-target applications. Its 130 mm case and 0.5-meter miniature coaxial ClickLoc cable enable accurate radial and axial measurements on shafts smaller than 51 mm and targets under 15 mm.

Built with AISI 304 stainless steel and a PPS probe tip, the probe withstands extreme temperatures (-52°C to +177°C) and harsh chemical environments. Advanced TipLoc and CableLoc designs ensure strong probe-tip bonding and cable retention up to 220 N (50 lb), providing long-term reliability.

Fully compatible with previous Bently Nevada 3300 RAM and 3000/7000-series systems, it supports seamless upgrades, reducing downtime and retrofit costs. Gold-plated ClickLoc connectors and optional protectors guarantee secure, contamination-resistant connections, while its optimized side-view design excels in restricted or challenging installation scenarios.

Compact, precise, and durable, the 3300 NSv Probe is engineered to deliver reliable vibration and position monitoring in demanding industrial environments.
