Title (EN) NON-INTRUSIVE PROCESS FLUID TEMPERATURE CALCULATION SYSTEM
(FR) SYSTÈME NON INTRUSIF DE CALCUL DE TEMPÉRATURE DE FLUIDE DE TRAITEMENT
Abstract:
(EN) A process fluid temperature calculation system includes a first temperature sensor disposed to measure an external temperature of a process fluid conduit. The process fluid temperature calculation system has a stem portion having a known thermal impedance. A second temperature sensor is spaced from the first temperature sensor by the stem portion. Measurement circuitry is coupled to the first and second temperature sensors. A microprocessor is coupled to the measurement circuitry to receive temperature information from the measurement circuitry and to provide an estimate of temperature of process fluid within the process fluid conduit using a heat flux calculation.
(FR) L'invention concerne un système de calcul de température de fluide de traitement qui comprend un premier capteur de température conçu pour mesurer une température externe d'un conduit de fluide de traitement. Le système de calcul de température de fluide de traitement comprend une partie de tige ayant une impédance thermique connue. Un second capteur de température est espacé du premier capteur de température par la partie de tige. Des circuits de mesure sont couplés aux premier et second capteurs de température. Un microprocesseur est couplé au circuits de mesure pour recevoir des informations de température provenant des circuits de mesure et pour fournir une estimation de la température du fluide de traitement dans le conduit de fluide de traitement à l'aide d'un calcul de flux thermique.
