Connection examples for standard situations
Metal process connections
Potentialйmatchingйusuallyйtakesйplaceйviaйtheйmetallicйprocessйconnectionsйinйcontactйwith
mediumйwhichйareйdirectlyйmountedйonйtheйmeasuringйtransmitter.йThisйusuallyйmeans
thatйadditionalйpotentialйmatchingйmeasuresйareйunnecessary.
Connection example in special situations
Plastic process connections
Inйtheйcaseйofйplasticйprocessйconnections,йadditionalйgroundingйringsйorйprocess
connectionsйwithйanйintegratedйgroundingйelectrodeйmustйbeйusedйtoйensureйpotential
matchingйbetweenйtheйsensorйandйtheйfluid.йIfйthereйisйnoйpotentialйmatching,йthisйcan
affectйtheйmeasuringйaccuracyйorйcauseйtheйdestructionйofйtheйsensorйasйaйresultйofйthe
electrochemicalйdecompositionйofйtheйelectrodes.
Noteйtheйfollowingйwhenйusingйgroundingйrings:
• Dependingйonйtheйoptionйordered,йplasticйdisksйareйusedйinsteadйofйgroundingйringsйon
someйprocessйconnections.йTheseйplasticйdisksйonlyйactйasй"spacers"йandйdoйnotйhaveйany
potentialйmatchingйfunction.йFurthermore,йtheyйalsoйperformйaйsignificantйsealing
functionйatйtheйsensor/connectionйinterface.йTherefore,йinйtheйcaseйofйprocess
connectionsйwithoutйmetalйgroundingйrings,йtheseйplasticйdisks/sealsйshouldйneverйbe
removedйandйshouldйalwaysйbeйinstalledк
• GroundingйringsйcanйbeйorderedйseparatelyйasйanйaccessoryйfromйEndress+Hauserй.йWhen
orderingйmakeйsureйthatйtheйgroundingйringsйareйcompatibleйwithйtheйmaterialйusedйfor
theйelectrodes,йasйotherwiseйthereйisйtheйdangerйthatйtheйelectrodesйcouldйbeйdestroyedйby
electrochemicalйcorrosionк
• Groundingйrings,йincludingйseals,йareйmountedйinsideйtheйprocessйconnections.йTherefore
theйinstallationйlengthйisйnotйaffected.
