Abstract
EL SENSOR DE PRESION SIRVE PARA AVERIGUAR LA PRESION DEL MEDIO DENTRO DE UN TUBO ELASTICO (10). EL ELEMENTO DE APRIETE (11) ACTUA SOBRE UNA BARRA (17) FIJADA EN UN LADO, QUE EN SU EXTREMO LIBRE TIENE UNA PIEZA DE INFLUENCIA (19). ESTA PIEZA DE INFLUENCIA (19) ES UN NUCLEO DENTRO DE UN CONJUNTO DE BOBINAS (22, 23), CAMBIANDO LA POSICION DEL NUCLEO, LAS FRECUENCIAS DE LAS BOBINAS. SE TOMAN NUMEROSOS VALORES DE MEDICION DE PRESION EN PERIODOS REGULARES Y DESPUES SE REALIZA EL CALCULO DEL VALOR MEDIO CON EL FIN DE OBTENER UN VALOR DE PRESION REPRESENTATIVO.
