Abstract

A pressure measuring device, comprising: a pressure measuring cell having a measuring membrane, at least one platform and a pressure chamber formed therebetween. An electrical transducer for transducing a deflection of the measuring membrane into a pressure dependent, primary signal; a cylindrical housing having a measuring cell chamber, in which the pressure measuring cell is arranged, and an end face pressure receipt opening in communication with the pressure duct; and an electronic circuit in the housing for operating the electrical transducer, and for processing the primary signal, and for outputting a measurement signal. The cylinder axis of the pressure measuring cell forms with the cylinder axis of the housing an angle, which amounts to not less than 80°, and which is especially preferably a right angle.
