Title
(EN) ACOUSTIC TEMPERATURE MEASUREMENT IN LAYERED ENVIRONMENTS
(FR) MESURE DE LA TEMPÉRATURE ACOUSTIQUE DANS DES ENVIRONNEMENTS EN COUCHES
Abstract
(EN) An apparatus for measuring temperature in a layered environment includes an ultrasound transducer positioned perpendicular to an exterior surface of a first layer. The ultrasound transducer is in communication with a computer processor, power source, and computer-readable memory. The processor is configured to: measure a thickness of the first layer; measure an exterior surface temperature of the first layer; calculate an impedance of the first layer based on the thickness and the exterior surface temperature; and calculate an interior surface temperature of the first layer based on the impedance and the exterior surface temperature of the first layer.
(FR) Un appareil pour mesurer la température dans un environnement en couches comprend un transducteur ultrasonore positionné perpendiculairement à une surface extérieure d'une première couche. Le transducteur ultrasonore est en communication avec un processeur informatique, un bloc d'alimentation et une mémoire lisible par ordinateur. Le processeur est configuré pour : mesurer l'épaisseur de la première couche ; mesurer la température de surface extérieure de la première couche ; calculer l'impédance de la première couche sur la base de l'épaisseur et de la température de surface extérieure ; et calculer la température de surface intérieure de la première couche sur la base de l'impédance et de la température de surface extérieure de la première couche.
