Patent

CA 2362171

To test the integrity of waterproof cases (10) for cameras and like apparatus to be used underwater, a casing (10) with a detector (20) is provided. The air inside the casing is pressurized and the detector (20) indicates leakage based on the difference between the pressurized air and atmospheric pressure. A decrease in pressure of the initial level of pressurized air implies leakage.

En vue de vérifier l'étanchéité des étuis (10) d'appareils photographiques et d'autres appareils similaires destinés à être utilisé sous l'eau, on dispose d'un boîtier (10) muni d'un détecteur (20). L'air à l'intérieur du boîtier est sous pression et le détecteur (20) signale la fuite à partir de la différence entre l'air pressurisé et la pression atmosphérique. Une baisse de niveau de la pression initiale de l'air pressurisé indique la présence de fuite.
