The invention relates to an arrangement for detecting and transmitting test data from a housing (10) including a pressure chamber (11) that is filled with a high-pressure fluid and is homogeneously pressurized via strip conductors (21) which are connected to a sensor (23) and are guided out of the housing (10). A circuit board (12), both faces of which are subjected to the pressure prevailing in the pressure chamber (11) and at least one portion (30) of which extends out of the housing is disposed inside the pressure chamber (11) as a support of the strip conductors (21). The housing (10) that encloses the pressure chamber (11) is separated on the plane of the printed board (12), the faces of the housing halves (13, 14) clamping the printed board (12) in such a way that radial forces exercised within the printed board when pressure is applied are absorbed by the housing.
