ABSTRACT:
A pressure transducer, including a housing having a housing axis and a measuring cell chamber defined in the housing. The measuring cell chamber is exposable to a pressure via an opening. The opening is surrounded by an annular, first sealing surface. A pressure measuring cell having a second sealing surface facing towards the opening, and a support surface facing away from the sealing surface sealing ring; and a clamping apparatus, which engages the housing are provided. The pressure measuring cell and the sealing ring are clamped by means of an axial clamping force in such a manner between the clamping apparatus and the first sealing surface, that the sealing ring is arranged pressure-tightly between the first sealing surface and the second sealing surface. The pressure transducer further includes a misalignment accommodating arrangement, which includes a first transmission body, which faces toward the opening, and a second transmission body, which is facing away from the opening. The axial clamping force is transmitted through the misalignment accommodating arrangement, from the clamping apparatus to the pressure measuring cell, and the first transmission body is tiltable relative to the second transmission body about two mutually perpendicular axes.
