Abstract
UN ENVASE (1) CERRADO SE INTRODUCE EN UNA CAMARA DE PRUEBA (3) PARA COMPROBAR SU HERMETICIDAD. UNA CAMARA DELANTERA (29) SE CARGA A UNA PRESION TEORICA Y SE CONECTA CON LA CAMARA DE PRUEBA (3) DE ALMACENA SEGUN TIEMPOS DETERMINADOS EN LOS LATERALES DE ENTRADA DE UNOS SENSORES (21) DIFERENCIADOS DE PRESION QUE COMPARAN LA PRESION EN LA CAMARA DE PRUEBA (3) CON LA PRESION DE REFERENCIA. CON LAS FUGAS EN EL CUERPO HUECO (1) LA COMPARACION DE PRESION SE REGISTRA COMO INDICADOR DE FUGAS.
