Abstract

SE PUEDEN UTILIZAR RESONADORES DE MODO DE CIZALLAMIENTO EN ESPESOR, QUE MIDEN SIMULTANEAMENTE LA DEPOSICION DE MASA Y LAS PROPIEDADES DE FLUIDOS, PARA MONITORIZAR EL PROCESAMIENTO DEL PETROLEO Y PRODUCTOS PETROQUIMICOS Y LOS SISTEMAS DE TRATAMIENTO DE AGUAS. SE PUEDEN AÑADIR SUSTANCIAS QUIMICAS ESPECIALES, DE FORMA PRECISA E INSTANTANEA, EN CONDICIONES DE CONTROL DETECTADAS MEDIANTE LOS RESONADORES DE MODO DE CIZALLAMIENTO EN ESPESOR. DICHOS RESONADORES SON CRISTALES PIEZOELECTRICOS UTILIZADOS CONJUNTAMENTE CON CIRCUITERIA DE OSCILADOR, QUE PUEDEN DETERMINAR LA MASA, ASI COMO LA VISCOSIDAD Y/O DENSIDAD DE UN FLUIDO EN CONTACTO CON LA SUPERFICIE PIEZOELECTRICA.
