Abstract

Procedimiento y dispositivo para medir y controlar la densidad aparente y otras características de piezas cerámicas. El procedimiento cuenta con una primera etapa de toma de ecos ultrasónicos en distintas zonas de una pieza cerámica cruda (4), una segunda etapa de tratamiento de la señal eléctrica correspondiente a dichos ecos que permite obtener valores de densidad, y una tercera etapa de corrección de los valores inadecuados mediante prensado de la pieza cerámica (4). El dispositivo correspondiente consiste en un transductor ultrasónico (1) que se aplica sobre la pieza cerámica (4) con interposición opcional de un gel (5) y que se conecta a una tarjeta emisora/receptora de ultrasonidos (6) conectada a su vez a una tarjeta digitalizadora (2); estando instaladas estas tarjetas (2 y 6) en un ordenador (3) que incluye los programas adecuados para obtener valores de densidad a partir de los ecos facilitados por el transductor (1).Procedure and device to measure and control the bulk density and other characteristics of ceramic pieces. The procedure has a first stage of taking ultrasonic echoes in different areas of a raw ceramic piece (4), a second stage of treatment of the electrical signal corresponding to said echoes that allows obtaining density values, and a third stage of correction of inappropriate values by pressing the ceramic piece (4). The corresponding device consists of an ultrasonic transducer (1) that is applied to the ceramic part (4) with optional interposition of a gel (5) and that is connected to an ultrasonic transmitter / receiver card (6) connected in turn to a digitizing card (2); these cards (2 and 6) being installed in a computer (3) that includes the appropriate programs to obtain density values from the echoes provided by the transducer (1).
