Abstract
Las propiedades de un producto de material resinoso son controladas en un sistema de fabricacion mediante la supervision y control de parámetros del proceso en línea. La supervision y control en línea incorpora un sistema de medicion in situ que puede supervisar el producto en el proceso mediante el uso de un dispositivo ultrasonico de corriente lateral. El dispositivo de corriente lateral proporciona ventajosamente mediciones en tiempo real en línea de las propiedades ac°sticas del proceso (por ejemplo, velocidad, atenuacion) bajo condiciones que son independientes de las condiciones de la corriente del proceso. El dispositivo de corriente lateral controla la temperatura, presion y régimen de flujo del producto mientras está dentro del dispositivo de corriente lateral y la velocidad y la atenuacion se miden bajo estas condiciones predeterminadas de temperatura, presion y régimen de flujo. Las propiedades ac°sticas (por ejemplo, velocidad, atenuacion) del producto, se usan para predecir las propiedades del producto y proporciona el sistema de control del proceso con análisis de las propiedades ac°sticas usando las relaciones derivadas entre las propiedades físicas del producto y las propiedades ac°sticas. Las diferencias entre las propiedades predichas y deseadas del producto se usan para controlar los parámetros del proceso. El proceso puede ser usado para una variedad de plantas de procesos químicos.
