Abstract

BALANZA ELECTRONICA DE GRAN PRECISION. CONSTA DE UN TRANSDUCTOR DE FUERZA (10) CON UNA PRIMERA SALIDA ANALOGICA (11); UN CONVERTIDOR (14) DIGITAL-ANALOGICO QUE TIENE UNA SEGUNDA SALIDA (15); UN PRIMER AMPLIFICADOR DIFERENCIAL (20) PARA RECIBIR AMBAS SALIDAS Y PRODUCIR UNA TERCERA (21); Y UN SEGUNDO AMPLIFICADOR (22) PARA RECIBIR LA TERCERA SALIDA Y LA DEL CONVERTIDOR (25) PARA PRODUCIR UNA NUEVA. EL PESO DEL OBJETO SE DETERMINA POR LA SALIDA DE UN AMPLIFICADOR DIFERENCIAL (39) Y LA PARTE RESTANTE SE OBTIENE DEL SEGUNDO AMPLIFICADOR (26), PERMITIENDO ADEMAS EL ACCIONAMIENTO DEL CONVERTIDOR EN EL MODO DE REALIMENTACION (30).
