Abstract

Un sistema sensor multi-funciones integrado tiene un cabezal teniendo una ranura para aceptar un tubo de un material deformable y una pluralidad de elementos sensores montados en las paredes de la ranura de cabezal para confrontar un tubo en la ranura, cada elemento sensor es para efectuar la percepci?n de una condici?n que se refiere a un l?quido en el tubo. Un circuito electr?nico integrado incluyendo un microprocesador opera para determinar las diversas condiciones de un l?quido que fluye en el tubo percibido por los elementos sensores, dichas condiciones incluyen detecci?n de burbujas de aire y/o part?culas mediante elementos sensores ultras?nicos, detecci?n de una oclusi?n en el flujo de l?quido al percibir la deformaci?n de la pared de tubo mediante un elemento sensor de fuerza, determinar la temperatura del l?quido mediante un elemento sensor de temperatura infrarroja, y determinar el color del l?quido mediante elementos ?pticos.
