Title (EN) HEAT TRANSFER METER
(FR) COMPTEUR DE TRANSFERT DE CHALEUR
Abstract: front page image
(EN)Portable, battery-driven device for measuring heat transfer coefficients (k-values). It uses an amplifier (1), which forms the quotient between the inner temperature minus the inner wall temperature on one hand and the inner temperature minus the outer temperature on the other hand. The temperature values of the first-mentioned substraction are obtained by thermal elements (7, 8), which are connected to the device. The difference according to the second one of the substractions is adjustable connected in a feed back circuit of the amplifier (1). The output quantity of the latter is supplied to an instrument (3) graduated in k-value. The thermal element for measuring of the inner wall temperature can be provided at the tip of a probe (9), and may consequently be conveniently applied to different places of a wall to be investigated.
(FR)Dispositif portatif alimente par une batterie pour mesurer les coefficients de transfert de chaleur (valeurs k). Il utilise un amplificateur (1) qui forme le quotient entre la temperature interieure moins la temperature de la paroi interieure d"une part et la temperature interieure moins la temperature exterieure d"autre part. Les valeurs des temperatures de la soustraction mentionnee en premier sont obtenues par des elements thermiques (7, 8) qui sont connectes au dispositif. La difference de la seconde soustraction est connectee de maniere reglable dans un circuit de reaction de l"amplificateur (1). La sortie de ce dernier est envoyee a un instrument (3) gradue en (valeurs k). L"element thermique de mesure de la temperature de la paroi interieure peut etre monte a l"extremite d"une sonde (9), et peut par consequent etre applique de maniere appropriee en differents endroits d"une paroi a inspecter.
