The 330904-00-25-10-01-00 is a Bently Nevada 3300 XL NSv Proximity Transducer System component. Specifically, it is a 3300 NSv probe designed for radial/axial vibration and position monitoring in centrifugal/refrigeration compressors, often used in small-target or tight space applications. It is often used with 3500 monitoring systems.

The primary uses for the 3300 XL NSv Transducer System are for areas where counter bore, sideview, or rearview restrictions limit the use of standard Bently Nevada 3300 and 3300 XL 5 and 8 mm Transducer Systems. It is also ideal for small target applications, such as measuring radial vibration on shafts smaller than 51 mm (2 in) or axial position on flat targets smaller than 15 mm (0.6 in). It is primarily used in the following applications on fluid-filmed bearing machines where a small shaft or reduced side-view is present:

Radial vibration and radial position measurements

Axial (thrust) position measurements

Tachometer and zero speed measurements

Phase reference (Keyphasor signals)
