Abstract

ESTE DISPOSITIVO COMPORTA UN CONDENSADOR DE MEDIDA (C1) DONDE UN ELECTRODO (10) ESTA UNIDO A UN PLATILLO DE PESO (12) Y EL OTRO (14) ESTA UNIDO A UN CIRCUITO DE MEDIDA DESTINADO A TRANSCRIBIR LAS VARIACIONES DE CAPACIDAD EN VALOR ANUNCIABLE CORRESPONDIENTE A LA MASA A MEDIR. SEGUN EL INVENTO, EL CIRCUITO DE MEDIDA COMPORTA OTRO CONDENSADOR (C0) LLAMADO DE REFERENCIA, MONTADO EN SERIE CON EL CONDENSADOR DE MEDIDA (C1), CADA UNO DE ESTOS CONDENSADORES (C0,C1) TIENEN UNA BORNA COMUN (18) UNIDA A UN DETECTOR DE TENSION NULA (26) ADAPTADO PARA EMITIR UNA SEÑAL (V1) QUE, POR EL INTERMEDIO DE UN CONMUTADOR (44) CONECTADO AL CONDENSADOR DE MEDIDA (C1), ESTA DESTINADO A EQUILIBRAR EL POTENCIAL EN LA BORNA COMUN (18) HASTA ALCANZAR UN POTENCIAL NULO. LA SEÑAL V1 ES PROPORCIONAL A LA VARIACION DE CAPACIDAD. ESTE CIRCUITO DE MEDIDA ESTA ADAPTADO PARA SER MONTADO EN UNA BALANZA PESA-PERSONAS.
