Title (EN) GENERAL PURPOSE ELECTRONIC THERMOMETER
(FR) THERMOMETRE ELECTRONIQUE A USAGES MULTIPLES
Abstract: front page image
(EN)An electronic thermometer comprising a platinum resistance sensor (10), a constant current source (20) which impresses a current through such sensor, an amplifier (22) which amplifies the resulting sensor voltage, and an analog to digital converter (30) which digitizes the amplifier signal and supplies the result to a microcomputer (40). The microcomputer (40) corrects for non-linearities in the resistance versus temperature relationship of the sensor and outputs to a display either: -- the resulting temperature equivalent; -- a calculated rate of temperature change; -- a temperature equivalent representing the temperature; or -- a temperature equivalent representing either the minimum or the maximum temperature measured since power has been applied to the instrument.
(FR)Thermometre electronique comprenant un detecteur a resistance de platine (10), une source de courant constant (20) qui fait passer un courant au travers d"un tel detecteur, un amplificateur qui amplifie la tension du detecteur, et un convertisseur analogique/digital (30) qui codifie en numerique le signal de l"amplificateur et fournit le resultat a un microcalculateur (40). Ce microcalculateur (40) corrige les indications non lineaires de la relation entre la resistance et la temperature du detecteur et ressort vers un affichage: soit l"equivalent de temperature qui en resulte, soit le taux calcule de changement de temperature soit un equivalent representant la temperature; ou bien soit un equivalent de temperature representant soit la temperature minimum soit la temperature, maximum mesuree depuis le moment ou l"appareil a ete mis sous tension.
