Abstract
UN MEDIDOR DE MAGNETISMO PARA DETECTAR EN EL CAMPO MAGNETICO DE DC. INCLUYE UN DISPOSITIVO SENSIBLE A LAS VARIACIONES DE CAMPO MAGNETICO QUE RESUENA A UNA FRECUENCIA CARACTERISTICA CONVIRTIENDO LA ENERGIA ALMACENADA EN SU INTERIOR COMO RESULTADO DE SER EXCITADA POR RADIACION ELECTROMAGNETICA A EL DOBLE DE LA FRECUENCIA DE RESONANCIA CUANDO ES INFLUIDO POR UN CAMPO DESVIADOR MAGNETICO DE DC DENTRO DE UN RANGO DE INTENSIDAD DE CAMPO PREDETERMINADA, EN EL CUAL LA AMPLITUD DE LA RESONANCIA VARIA CON VARIACIONES DE LA INTENSIDAD DEL CAMPO. EL APARATO ADEMAS INCLUYE UN CIRCUITO DE EXCITACION (12,14,R1,L1,C1) PARA EXCITAR EL DISPOSITIVO PARA RESONAR A LA FRECUENCIA CARACTERISTICA EN EL NIVEL DE AMPLITUD QUE PERMANECE CONSTANTE CUANDO LA INTENSIDAD DEL CAMPO DE DC NO VARIA DENTRO DEL RANGO DE INTENSIDAD DE CAMPO PREDETERMINADO; UNA FUENTE DE VOLTAJE DE DC (16) DENTRO DEL CIRCUITO DE EXCITACION PARA DESVIACION DEL DISPOSITIVO DENTRO DEL RANGO DE INTENSIDAD DE CAMPO PREDETERMINADA; Y UN INSTRUMENTO DE CAPTACION (18,20) PARA CAPTAR LA AMPLITUD DE LA RESONANCIA DEL DISPOSITIVO A LA FRECUENCIA CARACTERISTICA. UNA VARIACION EN LA AMPLITUD DE LA RESONANCIA CAPTADA INDICA UNA VARIACION EN LA INTENSIDAD DEL CAMPO DE INFLUENCIA MAGNETICA DE DC. EL APARATO ES UTILIZADO EN UNA VARIEDAD DE SISTEMAS DIFERENTES, INCLUYENDO UN SISTEMA PARA ACTUACION DE UN INSTRUMENTO DE SALIDA, TAL COMO UN CONTROLADOR DE SEÑAL DE TRAFICO, EN RESPUESTA A UNA PREDETERMINADA VARIACION UMBRAL EN UN CAMPO DE INFLENCIA MAGNETICA DE DC, TAL COMO OCURRE CUANDO UN VEHICULO A MOTOR SE MUEVE EN LA VECINDAD DEL APARATO; UN SISTEMA PARA INVESTIGAR LOS MATERIALES CUYA PRESENCIA AFECTA A LA INTENSIDAD DEL CAMPO DE INFLUENCIA MAGNETICA DE DC, TAL COMO TUBOS ENTERRADOS PARA DEPOSITOS DE MINERALES FERROMAGNETICOS; UN SISTEMA PARA COMUNICACION EN EL RANGO DE LA BAJA FRECUENCIA DEL ESPECTRO ELECTROMAGNETICO; Y UN SISTEMA PARA GUIAR UNA SONDA CON RESPECTO A LA LOCALIZACION DE UN OBJETO CUYA PRESENCIA ORIGINA UNA VARIACION EN LA INTENSIDAD DE UN CAMPO DE INFLUENCIA MAGNETICA.
