4. Design and function
4.1 Description
ThetemperaturetransmittermodelT12.x0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analoguesignalistransmittedtoaseries-connectedlogicunit
(e.g.aPLCoraswitchcontact)whereitismonitoredforanydeviation
overamaximumvalueorbelowaminimumvalue.
Forfailuremonitoring,thelogicunitmustbecapableofrecognising
bothHIalarms(adjustablefrom21...23.0mA)andLOalarms
(3.6mA).Theelectricalcomponentsofthetransmitteraremountedin
aplasticcaseandfullyencapsulated.
Thetemperaturetransmittermeetstherequirementsfor:
■
Explosionprotection(dependingontheversion)
■
Electromagneticcompatibilityinaccordancewith2004/108/EG
