Abstract
DISPOSITIVO SENSOR DE CAMPO MAGNETICO. DEL TIPO BASADO EN TECNOLOGIA DE "NUCLEO SATURADO" Y DETECCION DEL SEGUNDO ARMONICO, QUE COMPRENDE UN OSCILADOR MAESTRO (1) UTILIZADO COMO REFERENCIA DE UN GENERADOR (2) PARA LA GENERACION DE DOS SEÑALES DE FRECUENCIA BASICA DE FUNCIONAMIENTO Y DE FRECUENCIA DOBLE RESPECTIVAMENTE. LA PRIMERA ES AMPLIFICADA EN UN ELEVADOR DE POTENCIA (3) PARA EXCITAR LA BOBINA IMANADORA DE UNA CABEZA SENSORA (4). LA SEÑAL DE SALIDA DE LA BOBINA SENSORA ES FILTRADA EN UN FILTRO PASO BANDA (5), DEL TIPO DE CONDENSADORES CONMUTADOS PARA ENVIARLA POSTERIORMENTE A UN DETECTOR DE FASE (6) QUE RECIBE ADEMAS LA SEÑAL DE FRECUENCIA DOBLE PROCEDENTE DEL GENERADOR (2). LA SEÑAL OBTENIDA POR DICHO DETECTOR DE FASE (6) SE ENVIA A UN FILTRO PASO BAJO (7) CUYA SEÑAL DE SALIDA ES PROPORCIONAL AL CAMPO MAGNETICO DETECTADO. DISPONE ADEMAS DE UN BLOQUE DE COMUNICACIONES (8) Y DE UN BLOQUE DE AUTOCALIBRADO (9) PARA LA TRANSMISION DE DATOS A UN PUNTO REMOTO, Y CALIBRADO Y COMPROBACION TAMBIEN DESDE UN PUNTO REMOTO.
