Abstract
UNA CABEZA MEDIDORA (1) MIDE EL DESPLAZAMIENTO MEDIANTE LA VARIACION EN LA FRECUENCIA DE UN OSCILADOR DEBIDA AL MOVIMIENTO DE UN NUCLEO EN UNA BOBINA. LA SEÑAL DEL OSCILADOR SE USA PARA CONVERTIR UN GENERADOR DE SEÑALES DE CRISTAL DE ALTA FRECUENCIA (10) EN UN CONTADOR (12). LA CUENTA ES REPRESENTATIVA DEL CAMBIO DE LA FRECUENCIA DEL OSCILADOR Y DE ESTA FORMA DEL DESPLAZAMIENTO A MEDIR. LA CUENTA SE COMPARA MEDIANTE UN MICROPROCESADOR (14) CON UNA TABLA DE CONSULTA (16) ALMACENADA EN LA MEMORIA DURANTE LA CALIBRACION INICIAL. LOS DISPOSITIVOS ELECTRONICOS DE FUNCIONAMIENTO Y PROCESAMIENTO QUE ESTAN CONECTADOS A LA CABEZA SENSORA (1) SE MONTAN EN UN CONECTOR QUE PUEDE APLICARSE DIRECTAMENTE A LOS CONECTORES DE OTROS SENSORES PARA FORMAR UN BUS QUE CONECTE SENSORES MULTIPLES A UN ORDENADOR PRINCIPAL.
