Abstract

CIRCUITO DETECTOR DE CAMPO MAGNETICO. CONTIENE UN DETECTOR DE CAMPO MAGNETICO (1) CUYA SALIDA ESTA ACOPLADA EN RETORNO A TRAVES DE UN AMPLIFICADOR (3) CON LA ENTRADA (4) DEL DETECTOR DE CAMPO MAGNETICO (1) DE TAL FORMA QUE EN EL DETECTOR DE CAMPO MAGNETICO (1) SURTE EFECTO LA DIFERENCIA ENTRE UN CAMPO MAGNETICO (2) A MEDIR POSIBLEMENTE AMPLIFICADO Y UNA SEÑAL DE REACCION. LA SEÑAL DE REACCION ES UNA SEÑAL DE SALIDA DE UN DIVISOR DE TENSION (R1;2). CUANDO EL PRODUCTO DE LA SENSIBILIDAD DEL DETECTOR DE CAMPO MAGNETICO (1) FRENTE A TENSIONES ELECTRICAS DEL FACTOR DE AMPLIFICACION DE TENSION DEL AMPLIFICADOR (3) Y DEL FACTOR DE AMORTIGUACION DEL DIVISOR DE TENSION (R1;2) ES MUCHO MAYOR DE UNO LA CARACTERISTICA DEL DETECTOR DE CAMPO MAGNETICO (1) ES LINEAL E INDEPENDIENTE DE LA TEMPERATURA.
