Abstract

"dispositivo e método para a calibração de uma câmara de película para a detecção de vazamentos", por tratar a invenção de um método para a calibração de uma câmara de teste que envolve um volume interno (20), desenhado como uma câmara de película (12) compreendendo pelo menos uma região de parede flexível (14, 16) e sendo conectada em um modo de condução de gás a um sensor de pressão (30) e a uma bomba de vácuo (26), e através de uma válvula de calibração (34) a uma câmara de calibração (36) que envolve um volume de calibração (37), compreendendo as seguintes etapas: evacuação da câmara de película (12); medição da diferença de pressão no interior da câmara de película (12); depois que a evacuação foi concluída, é realizada a conexão do volume de calibração (37) em um modo de condução de gás ao volume interno (20) da câmara de película (12) enquanto a alteração da pressão é medida, sendo que a pressão na câmara de calibração (36) é maior do que a pressão na câmara de película (12) antes da conexão à câmara de película (12). um dispositivo correspondente é também revelado.
