The Bently Nevada 330901-00-90-05-02-05 3300 NSv Probe is part of the 3300 XL NSv Proximity Transducer System, designed for compact installations such as centrifugal air compressors, refrigeration units, and process gas compressors. It is ideal where space constraints prevent the use of standard 3300 and 3300 XL 5 mm or 8 mm systems. The system includes a 3300 NSv probe, extension cable, and a 3300 XL NSv Proximitor Sensor.

Engineered for tight or reduced side-view applications, the 3300 Series 330901-00-90-05-02-05 performs reliably in radial and axial measurements, even on shaft diameters under 51 mm or flat targets under 15 mm. It’s suitable for radial vibration, axial (thrust) position, tachometer, and phase reference (Keyphasor) signal measurements on fluid-film bearing machines.

The 3300 NSv Probe 330901-00-90-05-02-05 offers an average scale factor of 7.87 V/mm (200 mV/mil), the industry standard for eddy current probes. Its enhanced small-target capabilities offer a linear range of 1.5 mm, surpassing the older 3000-series 190 systems.

For upgrades, the 330901-00-90-05-02-05 Proximity Probes allows compatibility with existing 3300 RAM probes and extension cables, simplifying transitions. Full system upgrades from legacy 3000- or 7000-series models require replacement with NSv-compatible components like the Bently Nevada 330901-00-90-05-02-05.
