4. Design and function
4.1 Description
Thetemperaturetransmitterisusedforconvertingaresistancevalue
oravoltagevalueintoaproportionalcurrentsignal(4...20mA).
Thusthesensorsarepermanentlymonitoredfortheirfault-free
operation.
Thetransmittermeetstherequirementsfor:
■
FunctionalsafetyperIEC61508/IEC61511-1(dependingonthe
version)
■
Explosionprotection(dependingontheversion)
■
ElectromagneticcompatibilityinaccordancewithNAMUR
recommendationNE21
■
SignallingattheanalogueoutputinaccordancewithNAMUR
recommendationNE43

4.2 Operation in safety-related applications
ThemodelT32.xS.xxx-S(SILversion)hasbeen
designedforuseinsafety-relatedapplications.
Themarkingofthisdesignvariantisgiveninchapter2.6"Labelling,
safetymarking".Foroperationinsafety-relatedapplicationsthe
additionalrequirementsmustbeobserved(seesafetymanual
"InformationonfunctionalsafetyofmodelT32.xS").Theinstructions
containedinthismustbefollowedwithoutfail.
