Abstract

Un dispositivo per la determinazione della permeabilità all'aria di un nastro di materiale tessile comprende una testa di prova (2) per l'aspirazione o l'emissione di un flusso d'aria di misurazione attraverso il nastro di materiale, la quale testa può venire appoggiata a tenuta d'aria sul nastro di materiale ed è collegata ad un condotto (3) per l'aria, ed un dispositivo di misurazione (6) per il flusso d'aria di misurazione che è inserito nel condotto (3) per l'aria e che è costituito da un diaframma di misurazione (7) e da un manometro (8) collegato al condotto per l'aria su ambedue i lati del diaframma di misurazione (7). Per poter sfruttare la massima sensibilità di misurazione del manometro (8), il diaframma di misurazione (7) può venire regolato a guisa di un diaframma ad iride.
