Abstract

CIRCUIT COMPRENANT UN PREMIER AMPLIFICATEUR OPERATIONNEL DONT LES ENTREES POSITIVE ET NEGATIVE SONT CONNECTEES AUX DEUX PREMIERES BORNES DU PONT. LA SORTIE DE L'AMPLIFICATEUR OPERATIONNEL EST CONNECTEE A UNE TROISIEME BORNE DU PONT ET UN TRANSDUCTEUR DE CE PONT EST CONNECTE ENTRE LA SECONDE ET LA TROISIEME BORNE. L'ENTREE POSITIVE D'UN SECOND AMPLIFICATEUR OPERATIONNEL EST CONNECTEE A LA MASSE ET SON ENTREE NEGATIVE EST CONNECTEE A LA PREMIERE BORNE. UNE RESISTANCE DE REACTION EST MONTEE ENTRE LA SORTIE ET L'ENTREE NEGATIVE DU SECOND AMPLIFICATEUR. LE SIGNAL DE SORTIE DE CE SECOND AMPLIFICATEUR OPERATIONNEL REPRESENTE UNE REPONSE LINEAIRE A LA DEVIATION DU TRANSDUCTEUR ET IL EST PEU SENSIBLE AUX DECALAGES DE LA TENSION NULLE D'ENTREE DES DEUX AMPLIFICATEURS OPERATIONNELS. APPLICATION, PAR EXEMPLE, AUX PONTS AMPLIFICATEURS A TRANSDUCTEUR CONSTITUE D'UN EXTENSOMETRE.
