Description：

The Bently Nevada 330903-00-19-10-02-CN is a specialized part number for a 3300 XL NSv Proximity Probe. It is widely used for condition monitoring in industrial machinery, designed to measure radial vibration and axial position, particularly in areas with strict counterbore or sideview restrictions.

The primary uses for the 3300 XL NSv Transducer System arefor areas where counter bore, sideview, or rearviewrestrictions limit the use of standard Bently Nevada 3300 and3300 XL 5 and 8 mm Transducer Systems. It is also ideal forsmall target applications, such as measuring radial vibrationon shafts smaller than 51 mm (2 in) or axial position on flattargets smaller than 15 mm (0.6 in). It is primarily used in thefollowing applications on fluid-filmed bearing machineswhere 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)

Product Applications

Air and gas liquefaction plants (air separation plants): Monitor micron-level track vibration of the shafts of large centrifugal air compressors to prevent impeller rubbing against the cylinder.

Petrochemical and refining plants: Used in process gas compressors and high-speed, light-load hydrodynamic bearing machinery.

Large industrial refrigeration and freezing plants: Installed inside refrigeration compressors, its high chemical corrosion resistance protects against refrigerant corrosion.

Thermal and hydroelectric power plants: Primarily used for monitoring the axial displacement (thrust position) of bearing housings in small steam turbines, feedwater pump units, and high-speed auxiliary equipment.
