ABSTRACT:
Pressure or force measurement device for static or dynamic pressure measurement, in particular for high pressures or forces, having a housing including a pressure or force measuring cell, e.g., a piezoresistive or capacitive measuring cell. In such devices, service life and chemical resistance are problematic. The pressure measurement device includes the housing, a seal between the pressure medium and an inner chamber of the housing, a pressure measuring cell having a main face exposed to the pressure medium and which pressure measuring cell having a deflection when pressure loaded, which deflection leads to a relative movement between the pressure measuring cell and the housing in a region of the seal. In a region of the seal, the housing has spring-elastic properties. The pressure measurement device further includes a flange with an elastic sealing rib forming a through opening. The housing may be rotationally symmetrical with respect to the flange.
