Quick Detail

Description

The 330901-00-08-05-02-05 3300 NSv Proximity Probe is a state-of-the-art eddy current displacement transducer meticulously engineered by Bently Nevada for ultra-compact machinery monitoring applications. As a premier member of the 3300 NSv series, this specific 330901-00-08-05-02-05 configuration is purpose-built to deliver non-contact high-precision measurement of shaft vibration, displacement, and position where mounting space is exceptionally restricted and target surfaces are minimal. Distinguished by its extremely compact form factor with an overall case length of merely 0.8 inches and a minimalistic weight of 0.02kg, this proximity probe excels in installations where conventional sensors are physically impossible to deploy. Its design is a direct response to the growing need for advanced condition monitoring in modern, downsized rotating equipment.

This Bently Nevada proximity probe operates on robust eddy current technology, generating a highly stable output proportional to the gap between its tip and a conductive target. It features the industry-standard scale factor of 7.87 V/mm (200 mV/mil), ensuring seamless compatibility with a wide array of machinery monitoring systems. A defining feature of the 330901-00-08-05-02-05 model is its "Narrow Surface" (NSv) optimization, which allows for accurate measurements on small-diameter shafts and in environments with severely limited radial clearance. Unlike standard probes, this NSv proximity probe maintains excellent linearity across its full 1.8 mm linear range, providing a significant performance margin over older transducer designs.

Applications

This probe is indispensable for vibration and displacement monitoring in extremely compact rotating machinery such as high-speed spindles, small gearboxes, and miniaturized turbochargers. Its ultra-short 0.8-inch case length and minimal footprint allow it to be installed in bearing housings and assemblies where space is at an absolute premium, while its NSv (Narrow Surface) capability ensures accurate and reliable readings even from very small target areas, enabling early detection of unbalance, misalignment, and bearing wear.

The 330901-00-08-05-02-05 serves as a superior solution for axial position and thrust monitoring in confined machinery layouts. Its robust construction and ability to operate reliably across a vast temperature range (-50°C to +175°C) make it suitable for demanding applications like small steam turbines or compressors, where precise measurement of shaft position is critical for preventing catastrophic rubs and failures, all within the tight spatial constraints of modern machine design.

Featuring Multiple Agency Approvals and a stable output with low supply sensitivity (<2 mV/V), this probe is ideal for upgrading legacy monitoring systems in regulated and harsh environments. Its standardized 0.5-meter cable with ClickLoc connector facilitates straightforward retrofits, allowing plant engineers to enhance the monitoring capabilities of older equipment with a modern, highly reliable sensor that delivers precise data for condition-based maintenance strategies without requiring major mechanical modifications.

Specifications

Competitive Advantage

1.Unrivaled Miniaturization for Space-Critical Installations

The primary advantage of the 330901-00-08-05-02-05 probe is its exceptional compactness, featuring an overall case length of just 0.8 inches and a lightweight design of 0.02kg. This ultra-miniaturized form factor is specifically engineered to solve installation challenges in the most confined spaces, such as tight-bearing housings or compact machinery frames, where traditional proximity probes simply cannot fit, enabling comprehensive monitoring of previously inaccessible assets.

2.Precision Engineered for Small Targets with NSv Technology

This probe incorporates specialized Narrow Surface (NSv) technology, a competitive edge that optimizes its electromagnetic field for small-diameter shafts and minimal target surfaces. This allows the 330901-00-08-05-02-05 to achieve accurate and linear measurements—across a full 1.8 mm range—in scenarios where standard probes suffer from reduced accuracy or signal instability, making it the preferred choice for monitoring modern, downsized rotating equipment.

3.Exceptional Environmental Robustness and Stability

Designed to withstand extreme conditions, this sensor offers an industry-leading operating temperature range from -50°C to +175°C. This exceptional tolerance ensures stable performance and measurement accuracy in both freezing cryogenic applications and high-temperature turbine environments, minimizing downtime and maintenance needs. Coupled with its low output resistance (45 Ω) and minimal supply sensitivity, it delivers a stable, high-integrity signal that is resistant to environmental interference, guaranteeing reliable data for critical protection decisions.
