Freely programmable monitoring functions when 2 sensors
have been connected (dual sensor)
Thefollowingoptionsarenotavailableinthedierence
mode!
Redundancy/hotbackup:
Inthecaseofasensorerror(sensorbreak,lineresistancetoohighor
measuredvalueoutsidethemeasuringrangeofthesensor)ofoneof
thetwosensors,theprocessvaluewillbethevaluefromtheworking
sensoronly.Oncetheerrorisrectied,theprocessvaluewillagainbe
basedonthetwosensors,oronsensor1.
Ageingmonitoring(sensordriftmonitoring):
Anerrorsignalontheoutputisactivatedifthevalueofthetempe-
raturedierencebetweensensor1andsensor2ishigherthana
setvalue,whichcanbeselectedbytheuser.Thismonitoringonly
generatesasignaliftwovalidsensorvaluescanbedeterminedand
thetemperaturedierenceishigherthantheselectedlimitvalue.
(Cannotbeselectedforthe'Dierence'sensorfunctionality,sincethe
outputsignalalreadyindicatesthedierencevalue).
