The primary uses of the 3300 XL NSv Transducer System are in 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). The system 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)

The design of the 3300 XL NSv Transducer System allows it to replace both the 3300 RAM Transducer Systems and the 3000-series or 7000-series 190 Transducer System. Upgrades from the 3300 RAM system to the 3300 XL NSv system can use the existing probe, extension cable, and monitoring system with the 3300 XL NSv Proximitor Sensor. However, upgrades from the 3000-series or 7000-series Transducer System require replacing the probe, extension cable, and Proximitor Sensor with NSv components.
