Features:

  • Interface Between the Proximity Probe and 3300 XL NSv Transducer System
  • Integrates M8X1 Threaded Design with Protective Armor Construction
  • Functions as Part of the Complete 3300 XL NSv Proximity Transducer System
The Bently Nevada 330904-08-15-10-02-CN 3300 NSv Proximity Probe serves as the critical sensing element in the 3300 XL NSv Proximity Transducer System, providing accurate eddy current-based displacement measurements for machinery protection applications. The 330904-08-15-10-02-CN features an M8X1 thread configuration with protective armor, an unthreaded length of 80 mm, and an overall case length of 150 mm, with a total length of 1.0 meter (39 inches) to accommodate tight installation constraints. The 330904-08-15-10-02-CN incorporates a Miniature coaxial ClickLoc connector and standard cable construction, ensuring reliable signal transmission from the probe tip to the monitoring system. Multiple agency approvals qualify the 330904-08-15-10-02-CN for deployment in diverse industrial environments worldwide.

The 330904-08-15-10-02-CN provides essential measurement functions for machinery with severe installation restrictions, and is a critical component of the monitoring path, directly affecting the proper, normal operation of the overall transducer system. One 330904-08-15-10-02-CN probe is required per measurement point, working in conjunction with a 3300 NSv extension cable and a 3300 XL NSv Proximitor Sensor to form a complete channel. The 330904-08-15-10-02-CN occupies a minimal physical footprint within the machinery assembly and is always positioned at the measurement location closest to the target surface.

For small target applications, the 330904-08-15-10-02-CN enables precise measurement of radial vibration on shafts smaller than 51 mm (2 in) or axial position on flat targets smaller than 15 mm (0.6 in). In addition to standard radial vibration monitoring, the 330904-08-15-10-02-CN also performs axial (thrust) position measurements, tachometer and zero speed measurements, and phase reference (Keyphasor signal) acquisition. The 330904-08-15-10-02-CN executes these measurements using an Average Scale Factor of 7.87 V/mm (200 mV/mil), the most common output for eddy current transducers. Using this method, the 330904-08-15-10-02-CN delivers 1.5 mm (60 mils) of linear range, exceeding the linear range of the 3000-series 190 Transducer System it replaces, while its enhanced sideview and small target characteristics provide superior performance in constrained spaces compared to standard 3300 XL 5 and 8 mm systems.

The 330904-08-15-10-02-CN Bently Nevada 3300 NSv Proximity Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The 330904-08-15-10-02-CN is a 3300 NSv Proximity Probe specifically engineered for demanding industrial environments where installation space is severely constrained. This 330904-08-15-10-02-CN probe features an M8X1 thread configuration with protective armor, ensuring robust mechanical integrity in high-vibration settings. The 330904-08-15-10-02-CN incorporates an unthreaded length of 80 mm and an overall case length of 150 mm, with a total length of 1.0 meter (39 inches), making the 330904-08-15-10-02-CN suitable for precise positioning within compact machinery assemblies. The 330904-08-15-10-02-CN is equipped with a Miniature coaxial ClickLoc connector and utilizes standard cable construction, providing reliable signal transmission while maintaining multiple agency approvals for global deployment.

This 330904-08-15-10-02-CN proximity probe is specifically designed for handling tight installation constraints in critical rotating machinery, solving the fundamental challenge of monitoring equipment where counter bore, sideview, or rearview restrictions prevent the use of standard transducer systems. The 330904-08-15-10-02-CN addresses the critical need for accurate vibration and position monitoring in centrifugal air compressors, refrigeration compressors, and process gas compressors where physical space around bearing housings is extremely limited. By deploying the 330904-08-15-10-02-CN, maintenance engineers can obtain essential radial vibration and radial position measurements on fluid-filmed bearing machines featuring small shafts or reduced side-view clearances that would otherwise remain unmonitored.

The 330904-08-15-10-02-CN serves as a core component within the 3300 XL NSv Proximity Transducer System, working in conjunction with the 3300 NSv extension cable and 3300 XL NSv Proximitor Sensor to deliver comprehensive machinery protection. The 330904-08-15-10-02-CN excels in small target applications, providing precise measurement capabilities for shafts smaller than 51 mm (2 inches) in diameter and flat targets under 15 mm (0.6 inches), effectively solving the industry-wide problem of monitoring smaller rotating equipment that falls outside the operational range of conventional 5 mm and 8 mm probe systems. The 330904-08-15-10-02-CN enables critical axial (thrust) position measurements, tachometer and zero speed detection, and phase reference (Keyphasor signal) acquisition in environments where standard Bently Nevada 3300 and 3300 XL transducers cannot physically fit.

The 330904-08-15-10-02-CN offers seamless upgrade pathways from legacy systems, allowing facilities to modernize their monitoring infrastructure while maximizing existing investments. The 330904-08-15-10-02-CN can directly replace probes from 3300 RAM Transducer Systems and 3000-series or 7000-series 190 Transducer Systems, with the 330904-08-15-10-02-CN maintaining compatibility with existing monitoring hardware when paired with the appropriate NSv Proximitor Sensor. The 330904-08-15-10-02-CN delivers an Average Scale Factor of 7.87 V/mm (200 mV/mil), matching the most common output standard for eddy current transducers while providing 1.5 mm (60 mils) of linear range that exceeds the capabilities of the 3000-series 190 systems it replaces.
