Abstract

DISPOSITIVO DE MEDICION ELECTRICA QUE UTILIZA UNA RESISTENCIA EN DERIVACION (6), UN CIRCUITO ELECTRONICO DE MEDICION (5) QUE FLOTA EN EL POTENCIAL DE LA RESISTENCIA EN DERIVACION, Y UN PRIMER POTENCIOMETRO (R1, R2) INSTALADO ENTRE LA RESISTENCIA EN DERIVACION Y UN PUNTO NEUTRO (2) PARA PROPORCIONAR AL CIRCUITO (5) UNA PRIMERA SEÑAL DE TENSION. PARA BENEFICIARSE DE UN DESACOPLAMIENTO DE POTENCIAL ENTRE LA RESISTENCIA EN DERIVACION Y EL PUNTO INTERMEDIO (8) DEL PRIMER POTENCIOMETRO, EL DISPOSITIVO LLEVA UN BORNE SUPLEMENTARIO (4) CONECTADO A LA RESISTENCIA EN DERIVACION POR UN SEGUNDO POTENCIOMETRO (R3, R4), CUYO PUNTO INTERMEDIO (10) PROPORCIONA UNA SEGUNDA SEÑAL DE TENSION, UTILIZADO EN DIFERENCIAL CON LA PRIMERA.
