TheexampleshowsthesettingsforaPt100sensor.ThesettingsforNixxxsensors
orPT1000etc.are,however,similar.
Pt xxx or Ni xxx or YSI400
Selecttheresistancethermometertypeused:Pt100,Pt1000orNi500etc.The
numericalvaluesfortheplatinumandnickelthermometerscorrespondtotheirres-
istanceat0°C.
YSI400isaspecialNTCresistormainlyusedinthemedicalfield(temperature
range-80to250°C,resistanceof1660...6400Ω).
Measuring range
Selectthemeasurementrangebeingused.Dependingonthesensorversiononly
alimitedrangemaybepermissible.Refertothesensor'stechnicaldata.The
defaultisalwaysthesensor'smaximumpossiblemeasuringrange.Thechannel
receivesthestatus‘Measurementrangeoverrun/underrun’formeasurementsnot
withintherange.Channelstatusvaluesareavailableinstatusmonitoring.
Temp. Format
Selecttheunitofmeasurementinwhichthetemperatureistobedisplayed.Con-
versionisperformedautomaticallywithinthedevice.
°C:DegreesCelsius
K:Kelvin
°F:DegreesFahrenheit
R:Rankine
°R:DegreesRéaumur
Scaling
Enterthevalidrangeforsensorsignals.Thespecifiedrange(intheexample-260
°Cto+850°C)isusedasthedefaultforthedisplayareaforgraphicsinProfiSig-
nal.Thechannelreceivesthestatus"scalerangeoverrun"for"scalerangeunder-
run"whennotwithintherange.Channelstatusvaluesareavailableinstatus
monitoring.
Connection
Indicateherehowthesensorhasbeenconnected(thediagramdisplaystheselec-
tedwiring):
2 Wire:Thesensorisconnectedwithonlytwowires.Thisisrecommendedonly
forveryshortlinesandhighimpedancesensorsotherwisetheresultingvoltage
dropacrossthecircuitscanleadtomeasurementerrors.Alternatively,asensor
canbeusedwiththreeconnections,wheremeasurementtakesplacewithoutline
compensation.
