Abstract

Det er tilveiebragt en ikke-kontakt-aktig infrarød sensor (1) for måling av temperatur til et fjerntliggende objekt med forgrenede måle-elementer (6, 7). Et første element (6) er eksponert til det fjerntliggende objektet og danner derved en bestrålingsflux. Et andre element (7) er utformet i det samme lokale miljø som det første elementet (6), men adskilt fra bestråling fra det fjerntliggende objektet. Varmeoverføringen til begge elementene (6, 7) sammenlignes og den komponenten til Varmeoverføringen som korresponderer fluxen med det fjerntliggende objektet, isoleres og omdannes til et temperatursignal. Sensorsystemet innbefatter fortrinnsvis individuelle termiske kontroll- enheter (34, 38) på begge sensorelementene (6, 7), for nøyaktig å kontrollere varme- overføringen, samtidig som sensorelementet (6, 7) er termisk dekoblet. Dette gir en mer nøyaktig avlesning av temperaturen til det fjerntliggende objektet.
