Abstract
ES UN SENSOR DE PRESION (10) QUE RESPONDE ANTE UNA PROPORCION PREDETERMINADA DE CAMBIO DE PRESION EN EL MEDIO FLUIDO, QUE COMPRENDE UN ALOJAMIENTO (12) PROVISTO DE UNA CAMARA DE PRESION (40) QUE TIENE UNA PARED PERMEABLE (32) Y UN DIAFRAGMA FLEXIBLE (32) QUE SEPARA LA CAMARA DE PRESION (40) DEL SISTEMA SENSOR DE PRESION (38, 42) EN EL CUAL SE UTILIZA EL SENSOR. EL SENSOR PODRIA UTILIZARSE EN UNA RUEDA NEUMATICA Y EN ESTA UTILIDAD EL DIAFRAGMA FLEXIBLE (32) SE DOBLARA PARA ACTIVAR UN TRANSMISOR CUANDO LA PRESION DE LA RUEDA CAMBIE HACIA UNA TASA PELIGROSA. EL SENSOR NO ACTIVARA AL TRANSMISOR CUANDO LA TASA DE CAMBIO DE PRESION SEA MENOR QUE LA TASA DE PELIGRO.
