Introduction
Applications
RF8000isdesignedforleveldetectionandsimplepumpcontrolinavarietyofapplications:
 •Liquids,solids(powderandgranules),slurries,interfacedetection(forexample,oil/water),andfoamdetection
 •Foodsandpharmaceuticals
 •Chemicalandpetrochemical
 •Highpressureandtemperature
Function
RF8000isaversatilecapacitanceswitch,idealforleveldetectionofinterfaces,solids,liquids,slurries,andfoam,andfor
simplepumpcontrol.
Theswitchrespondstothepresenceofanymaterialwitharelativedielectricconstantof1.5ormorebydetectinga
changeincapacitance,whichisregisteredasachangeinoscillatingfrequency.
Theswitchcanbesettodetectbeforecontactoroncontactwiththeprobe.TheRF8000requiresaconnectionto
earth/groundforeffectivecapacitancemeasurement.
Thepowersupplyisgalvanicallyisolated.
Thematerialsusedintheprobeconstructionprovideahighlevelofchemicalresistance,andanexcellenttemperature
ratingontheprocesswettedportionoftheprobe:upto400°C(752°F).
RF8000isavailableintwomodels:thestandardmodel,andthedigitalmodelwithintegrallocaldisplay.
Features
 •Pottedconstructionprotectscomponentsfromshock,vibration,humidity,and/orcondensation
 •Highchemicalresistanceonprobes
 •Freelyprogrammablesetupcoverswiderangeofapplications/materials
 •IntegratedLocalUserInterface(LUI)foreaseofuse
 •Rodandropeversionsavailable
 •ActiveShieldminimizestheeffectofproductbuild-upatthesensormountingpoint
 •CommunicationviaPROFIBUSPA(proleversion3.0,ClassB)
 •IntrinsicallySafe(IS)transmitterdesignforhazardousareas(requiresexternalbarrierorISpowersupply)

Introduction
RF8000supportsPROFIBUScommunicationprotocol,andSIMATICPDMsoftware.
Basic PLC conguration with PROFIBUS PA
Programming
RF8000carriesoutitslevelmeasurementfunctionaccordingtothesetofbuilt-inparameters.Youcanmakeparameter
changeslocallyviathelocaluserinterface,orfromaremotelocationviaaPCusingSIMATICPDMsoftware.
RF8000Digitalcanbeusedeither:
 •asastandaloneunit,programmedlocallyusingthelocaluserinterface,or
 •installedaspartofanetwork,programmedremotelyusingSIMATICPDMonProbusPAnetwork(orlocally
 usingtheLocalUserInterface).
Alarm signalling
Thesolid-stateswitchcanbesettoreacteithertoadiagnosedfaultintheinstrument,ortoachangeintheprocesslevel.
Fault Signalling
RF8000canactivelyreportinformationonitsownstatusviaPROFIBUSPAwhenusedaspartofanetwork,orbymeans
ofapre-denedoutputstatusatthesolidstateswitchandontheLocalUserInterface(LUI).
