Description
The3300XL NSvProximity Transducer system is intended for usewith centrifugalair compressors, refrigeration compressors, process gas compressors and other machines with tight installation requirements. The3300XL NSvProximity Transducer System consists of:
•a 3300NSvprobe
•a 3300NSvextension cable
•a 3300XL NSvProximitor Sensor(1)
Theprimary uses for the3300XL NSvTransducer System are for areas wherecounter bore, sideview or rearview restrictions limit theuseofstandard Bently Nevada 3300and 3300XL 5 and 8mm Transducer Systems. It is also idealfor smalltarget applications, such as measuring radialvibration on shafts smaller than 51mm (2 in) or axialposition on flat targets smaller than 15mm (0.6in). It is primarily used in the following applications on fluid-filmed bearing machines wherea smallshaft or reduced side-view is present:
•Radialvibration and radialposition measurements
•Axial(thrust) position measurements
•Tachometer and zero speed measurements
•Phasereference(Keyphasor signals)
The3300XL NSvTransducer System design allows it to replace both the3300RAMTransducer Systems and the3000-series or 7000-series 190Transducer System. Upgrades from the 3300RAMsystem to the3300XL NSvsystem may usethe existing probe, extension cable, and monitoring system with 3300XL NSvProximitor Sensor. Upgrades from the3000-series or 7000-series Transducer System must replacetheprobe, extension cableand Proximitor Sensor with NSvcomponents.

The3300XL NSvTransducer System has an AverageScaleFactor of7.87V/mm (200 mV/mil), which is themost common output for eddy current transducers. Its enhanced sideview and smalltarget characteristics giveit a shorter linear rangethan theBently Nevada 3300XL-series 5and 8mm Transducer System. With The1.5mm (60mils) oflinear range exceeds thelinear rangeofthe3000-series 190 Transducer System.
Although theterminals and connector on theProximitor Sensor have protection against electrostatic discharge, takereasonableprecautions to avoid electrostatic dischargeduring handling.
Proximitor Sensor
The3300XL NSvProximitor Sensor has similar features to thosefound in the3300XL 8mm Proximitor Sensor. Its thin design allows the user to mount it in either a high-density DIN-rail installation or a moretraditionalpanelmount configuration. Improved RFI/EMIimmunity allows the3300XL NSvProximitor Sensor to achieveEuropean CE mark approvals without any specialmounting considerations. This RFI immunity also prevents nearby high frequency radio signals from adversely affecting the transducer system. SpringLoc terminalstrips on theProximitor Sensor requireno special installation tools and facilitatefaster, highly robust field wiring connections.
Proximity Probe and Extension Cable
The3300NSvprobeand extension cableare mechanically and electrically compatibleand interchangeablewith Bently Nevada’s previous 3300RAMproximity probeand extension cable. TheNSvprobehas increased chemical resistancecompared to the3300RAMprobe, which allows its usein many process compressor applications. Theside-view characteristics ofthe3300NSvprobearealso superior to thoseofthe3000-series 190probe when gapping the3300NSvprobeat thesame distancefrom theprobetarget.
The3300NSvprobecomes in varying probe caseconfigurations, including armored and unarmored ¼ -28, 3⁄8-24, M8X1and M10X1 probethreads. Thereversemount 3300NSv probecomes standard with either 3⁄8-24or M10X1threads. Allcomponents ofthe transducer system havegold-plated brass ClickLocconnectors. ClickLoc connectors lock into placeand prevent theconnection from loosening. Thepatented TipLocmolding method provides a robust bond between the probetip and theprobebody. Bently Nevada’s patented CableLocdesign provides 220N(50 lb) ofpullstrength and securely attaches the probecableto theprobetip. Connector protectors arerecommended for useon the probe-to-extension cableconnection, as well as on thecable-to-Proximitor Sensor connection. Connector protectors prevent most liquids from entering into theClickLoc connectors and adversely affecting the electricalsignal(2).
Notes:
(1)ProximitorSensors aresupplied by default from thefactory calibrated to AISI4140steel. Calibration to other target materials is available upon request.
(2)Siliconetapeis also provided with each 3300NSvextension cableand can beused instead ofconnector protectors. Siliconetape is not recommended in applications wherethe probe-to-extension cableconnection willbe exposed to turbineoil.
