Description：

The 3300 XL NSv Proximity Transducer system is intended foruse with centrifugal air compressors, refrigeration compressors, process gas compressors, and other machineswith tight installation requirements. The 3300 XL NSv ProximityTransducer System consists of:

a 3300 NSv probe

a 3300 NSv extension cable

a 3300 XL NSv Proximitor Sensor(1)

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

Oil & Gas: Widely used in centrifugal compressors, reciprocating compressors, and natural gas turbines in offshore drilling platforms, refineries, and gas pipelines.

Power Generation: Bearing monitoring in small and medium-sized steam turbines, gas turbines, generator bearing housings, and large auxiliary equipment (such as feedwater pumps and forced draft fans) deployed in thermal power plants, nuclear power plants, and hydropower plants.

Chemical & Petrochemical: Used for online continuous monitoring of rotating power equipment such as various chemical process pumps, high-speed separators, refrigeration compressors, and extruders.

Steel & Metallurgy: Applied to critical units requiring harsh high-temperature and high-vibration environments, such as blast furnace blowers, high-precision rolling mill gearboxes, and large exhaust fans.
