Abstract
A pressure sensor for static and/or dynamic pressure measurement of a liquid, flowable, or gaseous medium is described, with a housing (2) and with a pressure measuring cell (3), on the side facing the medium an opening (4) being formed through which one side (5) of the pressure measuring cell (3) is directly or indirectly in contact with the medium to be monitored, and the pressure measuring cell (3) converting the pressure to be monitored into a proportional measurement signal by means of an electromechanical converter.The pressure sensor as claimed in the invention can have both a small outside diameter and can also be economically produced by the housing (2) sitting on the pressure measuring cell (3) and the housing (2) and the pressure measuring cell (3) being connected to one another on the face side so that the pressure measuring cell (3) is at least in part a component of the outer surface of the pressure sensor (1) and thus is not surrounded by the housing (2).
