Quick Detail

Description

The Bently Nevada 330901-02-47-10-01-00 3300 NSv Proximity Probe epitomizes advanced eddy-current sensing technology, engineered specifically for critical machinery condition monitoring applications where extreme spatial constraints and uncompromising measurement accuracy are required. Manufactured by Bently Nevada, a world-renowned leader in industrial asset protection, this specialized proximity probe is a core component of the innovative 3300 NSv series. It is masterfully designed for non-contact measurement of displacement, vibration, and position on small conductive targets and in environments with severe mounting and side-clearance limitations. Its defining Narrow Surface (NSv) technology enables precise and stable readings where conventional probes fail, making it an essential tool for safeguarding high-speed, compact rotating assets through effective predictive maintenance.

This sensor distinguishes itself with an exceptionally compact mechanical profile, featuring a minimal unthreaded length of 0.2 inches and an overall case length of 4.7 inches. Its slim dimensions (1.24x1x113 cm) and ultra-lightweight construction (0.03 kg) permit straightforward installation in the most confined spaces, such as tight bearing housings, bulkheads, and densely packed equipment enclosures, without imposing extra load on sensitive machinery components. The probe is equipped with a standard cable measuring 1.0 meter (39 inches), terminated with a reliable Miniature coaxial ClickLoc connector and protective boot, ensuring secure, interference-resistant signal transmission and hassle-free integration with monitoring systems.

Operating on the industry-proven Average Scale Factor (ASF) of 7.87 V/mm (200 mV/mil), the 330901-02-47-10-01-00 probe delivers a highly linear and stable voltage output that is directly proportional to the distance between its tip and the target surface. This ensures reliable detection of minute dynamic movements for accurate shaft displacement and rotor position monitoring. Built for durability, this Bently Nevada sensor maintains consistent performance across a wide operational temperature range, solidifying its role as a vital component for protecting critical rotating assets—including small centrifugal compressors, high-speed pumps, and turbines—in demanding industries such as power generation, oil & gas, and chemical processing.

Applications

This probe is ideally engineered for monitoring miniaturized and small-scale rotating machinery where space is at a premium. Its 0.2-inch unthreaded length and 4.7-inch overall case length enable seamless installation in the cramped bearing housings of compact centrifugal pumps, microturbines, or high-speed electric motors. Coupled with its "Narrow Surface" (NSv) optimization, it delivers precise measurement of radial vibration and axial position on small-diameter shafts or minimal target areas, providing crucial data for early fault detection and dynamic balancing of such equipment.

With a robust operating temperature range of -44°C to +163°C, this sensor is perfectly suited for harsh industrial environments. It delivers stable performance in applications ranging from high-temperature steam turbine casings to cryogenic compressors, continuously monitoring critical clearance changes between rotating and stationary components. Its minimal signal drift ensures long-term reliability for continuous condition monitoring in demanding sectors like power generation, oil refining, and chemical processing.

Serving as a plug-and-play solution, this probe is an optimal direct replacement for legacy eddy sensor systems, such as the older 190 series. Its standard 1-meter cable and Miniature coaxial ClickLoc connector simplify field wiring, while its 50 Ω output resistance guarantees seamless signal compatibility with modern monitoring systems like the 3300 series. This facilitates cost-effective system modernization and performance upgrades with minimal retrofit effort and downtime.

Specifications

Competitive Advantage

1. Ultra-Compact Design Engineered for Extreme Spatial Constraints

This probe sets itself apart with its exceptionally compact mechanical design, featuring a mere 0.2-inch unthreaded section and a 4.7-inch overall case length. Combined with its slim form factor (1.24x1x113 cm), it achieves unparalleled space savings, allowing integration into cavities and mounting locations where standard probes simply cannot fit. This is particularly critical for modern, highly integrated machinery like compact compressors and gearboxes, enabling high-performance monitoring without design compromise.

2. Proprietary NSv Technology for Small-Target Applications

Unlike standard proximity probes, this model incorporates unique Narrow Surface (NSv) optimization, which calibrates its electromagnetic field specifically for small target surfaces. This technology ensures stable, linear, and high-precision measurements even in applications with minimal side-clearance or on small-diameter shafts. It effectively solves the industry challenge of monitoring vibration in small, high-speed rotating equipment, delivering performance far superior to previous-generation transducers.

3. Superior Environmental Robustness and Seamless Integration

The probe offers exceptional environmental adaptability with a wide operating temperature range of -44°C to +163°C, guaranteeing long-term stability and reliability in both extreme high-heat and cryogenic industrial settings, thereby reducing false alarms caused by sensor drift. Furthermore, its standardized 1-meter cable, ClickLoc connector, and 50 Ω output resistance ensure plug-and-play compatibility with mainstream monitoring systems like the Bently Nevada 3300 series. This significantly simplifies installation, commissioning, and legacy system upgrade processes, reducing total lifecycle maintenance costs.
