Abstract

"dispositivo de detecção de vazamentos e método para medição da pressão diferencial", por tratar a presente invenção de um dispositivo de detecção de vazamentos, para a medição da pressão diferencial entre uma câmara de teste (10) e uma câmara de referência, que pode ser separada da câmara de teste (10) de uma forma estanque a gás, por meio de uma primeira válvula de retenção (24), sendo que um sensor de pressão diferencial (34) é conectado à câmara de referência e à câmara de teste (10), para a medição da pressão diferencial entre a pressão interna da câmara de referência e a pressão interna da câmara de teste (10), caracterizado pelo fato de a câmara de teste (10) e a câmara de referência terem, cada uma, pelo menos uma região de parede formada a partir de uma película flexível, sendo que a proporção entre o volume da câmara de teste (20) e a área de superfície da região de parede flexível da câmara de teste (10) adjacente ao volume da câmara de teste (20) e a proporção entre o volume da câmara de referência e a área de superfície da região de parede flexível da câmara de referência adjacente ao volume da câmara de referência são substancialmente iguais.
