METHOD FOR TESTING THE TIGHTNESS OF A HOUSING

摘要

The invention relates to a measuring arrangement (20) and a method (100) for determining a leakage rate (52) on a housing (22) used for accommodating an apparatus (24) for satellites and space applications. Said measuring arrangement (20) comprises a housing (22), a pressure sensor (26), a temperature sensor (28), a time measuring instrument (54), and an evaluation unit (48). The pressure sensor (26) is arranged in the housing (22) and is suitable for detecting a pressure within the housing (22). The evaluation unit (48) is designed to determine a leakage rate (52) on the basis of output signals (42, 44) of the pressure sensor (26) and the temperature sensor (28) and on the basis of the points in time (50) of the measurements.
