Abstract

Un procedimiento y un dispositivo para la medición del volumen de objetos de materiales higroscópicos con geometría compleja mediante sistema neumático. El dispositivo comprende un sistema de dos cámaras con transductores de presión absoluta incorporados, una en la que se alojará el objeto a medir y otra en la que se acumula aire comprimido. La alimentación de aire comprimido al sistema pasa previamente por un sistema de limpieza. La presión del aire incorporado es controlada mediante un limitador de presión. La medición del volumen del objeto se realiza en base al volumen de las dos cámaras y a la medición de las presiones que se alcanzan en las mismas durante el ciclo de medición, al poner en presión una de ellas y después abrir la llave de paso que las comunica. El proceso resulta aplicable a materiales higroscópicos de geometría compleja, como madera, péllets, piensos granulados o suelos.A procedure and a device for measuring the volume of objects of hygroscopic materials with complex geometry by means of a pneumatic system. The device comprises a two-chamber system with built-in absolute pressure transducers, one in which the object to be measured will be housed and another in which compressed air is accumulated. The compressed air supply to the system passes previously through a cleaning system. The built-in air pressure is controlled by a pressure limiter. The measurement of the volume of the object is carried out based on the volume of the two chambers and the measurement of the pressures that are reached in them during the measurement cycle, by pressing one of them and then opening the stopcock that communicates The process is applicable to hygroscopic materials of complex geometry, such as wood, pellets, granulated feed or soil.
