New and Original Bently Nevada 3500/65-01-02 Description The 3300 XL NSv Proximity Transducer system is intended forusewith centrifugal air compressors, refrigeration compressors, process gas compressors, and other machineswith tight installation requirements. The 3300 XL NSv ProximityTransducer System consists of: la 3300 NSv probe la 3300 NSv extension cable la 3300 XL NSv Proximitor Sensor(1) 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 radialvibration 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: lRadialvibration and radial position measurements lAxial (thrust) position measurements lTachometer and zero speed measurements lPhase reference (Keyphasor signals) The 3300 XL NSv Transducer System design 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 may use the existing probe, extension cable, and monitoring system with 3300 XL NSv Proximitor Sensor. Upgrades from the 3000-series or 7000-series Transducer System must replace the probe, extension cable, and Proximitor Sensor with NSv components. The 3300 XL NSv Transducer System has anAverage Scale Factor of 7.87 V/mm (200 mV/mil),which is the most common outputfor eddy current transducers. Its enhanced side- view and small target characteristics giveita shorter linear range than the Bently Nevada 3300 XL-series 5 and 8 mm Transducer System. The 1.5 mm (60 mils) of linear range exceedsthe linear range of the 3000-series 190 Transducer System.
